-/**
- * @ingroup libavc
- * @defgroup lavc_encdec send/receive encoding and decoding API overview
- * @{
- *
- * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
- * avcodec_receive_packet() functions provide an encode/decode API, which
- * decouples input and output.
- *
- * The API is very similar for encoding/decoding and audio/video, and works as
- * follows:
- * - Set up and open the AVCodecContext as usual.
- * - Send valid input:
- *   - For decoding, call avcodec_send_packet() to give the decoder raw
- *     compressed data in an AVPacket.
- *   - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
- *     containing uncompressed audio or video.
- *
- *   In both cases, it is recommended that AVPackets and AVFrames are
- *   refcounted, or libavcodec might have to copy the input data. (libavformat
- *   always returns refcounted AVPackets, and av_frame_get_buffer() allocates
- *   refcounted AVFrames.)
- * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
- *   functions and process their output:
- *   - For decoding, call avcodec_receive_frame(). On success, it will return
- *     an AVFrame containing uncompressed audio or video data.
- *   - For encoding, call avcodec_receive_packet(). On success, it will return
- *     an AVPacket with a compressed frame.
- *
- *   Repeat this call until it returns AVERROR(EAGAIN) or an error. The
- *   AVERROR(EAGAIN) return value means that new input data is required to
- *   return new output. In this case, continue with sending input. For each
- *   input frame/packet, the codec will typically return 1 output frame/packet,
- *   but it can also be 0 or more than 1.
- *
- * At the beginning of decoding or encoding, the codec might accept multiple
- * input frames/packets without returning a frame, until its internal buffers
- * are filled. This situation is handled transparently if you follow the steps
- * outlined above.
- *
- * In theory, sending input can result in EAGAIN - this should happen only if
- * not all output was received. You can use this to structure alternative decode
- * or encode loops other than the one suggested above. For example, you could
- * try sending new input on each iteration, and try to receive output if that
- * returns EAGAIN.
- *
- * End of stream situations. These require "flushing" (aka draining) the codec,
- * as the codec might buffer multiple frames or packets internally for
- * performance or out of necessity (consider B-frames).
- * This is handled as follows:
- * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
- *   or avcodec_send_frame() (encoding) functions. This will enter draining
- *   mode.
- * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
- *   (encoding) in a loop until AVERROR_EOF is returned. The functions will
- *   not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
- * - Before decoding can be resumed again, the codec has to be reset with
- *   avcodec_flush_buffers().
- *
- * Using the API as outlined above is highly recommended. But it is also
- * possible to call functions outside of this rigid schema. For example, you can
- * call avcodec_send_packet() repeatedly without calling
- * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
- * until the codec's internal buffer has been filled up (which is typically of
- * size 1 per output frame, after initial input), and then reject input with
- * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
- * read at least some output.
- *
- * Not all codecs will follow a rigid and predictable dataflow; the only
- * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
- * one end implies that a receive/send call on the other end will succeed, or
- * at least will not fail with AVERROR(EAGAIN). In general, no codec will
- * permit unlimited buffering of input or output.
- *
- * This API replaces the following legacy functions:
- * - avcodec_decode_video2() and avcodec_decode_audio4():
- *   Use avcodec_send_packet() to feed input to the decoder, then use
- *   avcodec_receive_frame() to receive decoded frames after each packet.
- *   Unlike with the old video decoding API, multiple frames might result from
- *   a packet. For audio, splitting the input packet into frames by partially
- *   decoding packets becomes transparent to the API user. You never need to
- *   feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
- *   no data was read from the packet).
- *   Additionally, sending a flush/draining packet is required only once.
- * - avcodec_encode_video2()/avcodec_encode_audio2():
- *   Use avcodec_send_frame() to feed input to the encoder, then use
- *   avcodec_receive_packet() to receive encoded packets.
- *   Providing user-allocated buffers for avcodec_receive_packet() is not
- *   possible.
- * - The new API does not handle subtitles yet.
- *
- * Mixing new and old function calls on the same AVCodecContext is not allowed,
- * and will result in undefined behavior.
- *
- * Some codecs might require using the new API; using the old API will return
- * an error when calling it. All codecs support the new API.
- *
- * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
- * would be an invalid state, which could put the codec user into an endless
- * loop. The API has no concept of time either: it cannot happen that trying to
- * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
- * later accepts the packet (with no other receive/flush API calls involved).
- * The API is a strict state machine, and the passage of time is not supposed
- * to influence it. Some timing-dependent behavior might still be deemed
- * acceptable in certain cases. But it must never result in both send/receive
- * returning EAGAIN at the same time at any point. It must also absolutely be
- * avoided that the current state is "unstable" and can "flip-flop" between
- * the send/receive APIs allowing progress. For example, it's not allowed that
- * the codec randomly decides that it actually wants to consume a packet now
- * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
- * avcodec_send_packet() call.

-     * this means is, you may set however many entries in buf[] you feel necessary.
-     * Each buffer must be reference-counted using the AVBuffer API (see description
-     * of buf[] below).
-     *
-     * The following fields will be set in the frame before this callback is
-     * called:
-     * - format
-     * - width, height (video only)
-     * - sample_rate, channel_layout, nb_samples (audio only)
-     * Their values may differ from the corresponding values in
-     * AVCodecContext. This callback must use the frame values, not the codec
-     * context values, to calculate the required buffer size.
-     *
-     * This callback must fill the following fields in the frame:
-     * - data[]
-     * - linesize[]
-     * - extended_data:
-     *   * if the data is planar audio with more than 8 channels, then this

-     *     to all data planes. data[] must hold as many pointers as it can.
-     *     extended_data must be allocated with av_malloc() and will be freed in
-     *     av_frame_unref().
-     *   * otherwise extended_data must point to data
-     * - buf[] must contain one or more pointers to AVBufferRef structures. Each of
-     *   the frame's data and extended_data pointers must be contained in these. That
-     *   is, one AVBufferRef for each allocated chunk of memory, not necessarily one
-     *   AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
-     *   and av_buffer_ref().
-     * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
-     *   this callback and filled with the extra buffers if there are more
-     *   buffers than buf[] can hold. extended_buf will be freed in
-     *   av_frame_unref().
-     *
-     * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
-     * avcodec_default_get_buffer2() instead of providing buffers allocated by
-     * some other means.
-     *
-     * Each data plane must be aligned to the maximum required by the target
-     * CPU.

-     *
-     * avcodec_align_dimensions2() should be used to find the required width and
-     * height, as they normally need to be rounded up to the next multiple of 16.
-     *
-     * Some decoders do not support linesizes changing between frames.
-     *
-     * If frame multithreading is used and thread_safe_callbacks is set,
-     * this callback may be called from a different thread, but not from more
-     * than one at once. Does not need to be reentrant.

-     * to a smaller value in the output frame.
-     *
-     * As a convenience, av_samples_get_buffer_size() and

-/**
- * Create and return a AVHWFramesContext with values adequate for hardware
- * decoding. This is meant to get called from the get_format callback, and is
- * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
- * This API is for decoding with certain hardware acceleration modes/APIs only.
- *
- * The returned AVHWFramesContext is not initialized. The caller must do this
- * with av_hwframe_ctx_init().
- *
- * Calling this function is not a requirement, but makes it simpler to avoid
- * codec or hardware API specific details when manually allocating frames.
- *
- * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
- * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
- * it unnecessary to call this function or having to care about
- * AVHWFramesContext initialization at all.
- *
- * There are a number of requirements for calling this function:
- *
- * - It must be called from get_format with the same avctx parameter that was
- *   passed to get_format. Calling it outside of get_format is not allowed, and
- *   can trigger undefined behavior.
- * - The function is not always supported (see description of return values).
- *   Even if this function returns successfully, hwaccel initialization could
- *   fail later. (The degree to which implementations check whether the stream
- *   is actually supported varies. Some do this check only after the user's
- *   get_format callback returns.)
- * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
- *   user decides to use a AVHWFramesContext prepared with this API function,
- *   the user must return the same hw_pix_fmt from get_format.
- * - The device_ref passed to this function must support the given hw_pix_fmt.
- * - After calling this API function, it is the user's responsibility to
- *   initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
- *   and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
- *   before returning from get_format (this is implied by the normal
- *   AVCodecContext.hw_frames_ctx API rules).
- * - The AVHWFramesContext parameters may change every time time get_format is
- *   called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
- *   you are inherently required to go through this process again on every
- *   get_format call.
- * - It is perfectly possible to call this function without actually using
- *   the resulting AVHWFramesContext. One use-case might be trying to reuse a
- *   previously initialized AVHWFramesContext, and calling this API function
- *   only to test whether the required frame parameters have changed.
- * - Fields that use dynamically allocated values of any kind must not be set
- *   by the user unless setting them is explicitly allowed by the documentation.
- *   If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
- *   the new free callback must call the potentially set previous free callback.
- *   This API call may set any dynamically allocated fields, including the free
- *   callback.
- *
- * The function will set at least the following fields on AVHWFramesContext
- * (potentially more, depending on hwaccel API):
- *
- * - All fields set by av_hwframe_ctx_alloc().
- * - Set the format field to hw_pix_fmt.
- * - Set the sw_format field to the most suited and most versatile format. (An
- *   implication is that this will prefer generic formats over opaque formats
- *   with arbitrary restrictions, if possible.)
- * - Set the width/height fields to the coded frame size, rounded up to the
- *   API-specific minimum alignment.
- * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
- *   field to the number of maximum reference surfaces possible with the codec,
- *   plus 1 surface for the user to work (meaning the user can safely reference
- *   at most 1 decoded surface at a time), plus additional buffering introduced
- *   by frame threading. If the hwaccel does not require pre-allocation, the
- *   field is left to 0, and the decoder will allocate new surfaces on demand
- *   during decoding.
- * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
- *   hardware API.
- *
- * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
- * with basic frame parameters set.
- *
- * The function is stateless, and does not change the AVCodecContext or the
- * device_ref AVHWDeviceContext.
- *
- * @param avctx The context which is currently calling get_format, and which
- *              implicitly contains all state needed for filling the returned
- *              AVHWFramesContext properly.
- * @param device_ref A reference to the AVHWDeviceContext describing the device
- *                   which will be used by the hardware decoder.

-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-/**
- * @ingroup libavc
- * @defgroup lavc_encdec send/receive encoding and decoding API overview
- * @{
- *
- * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
- * avcodec_receive_packet() functions provide an encode/decode API, which
- * decouples input and output.
- *
- * The API is very similar for encoding/decoding and audio/video, and works as
- * follows:
- * - Set up and open the AVCodecContext as usual.
- * - Send valid input:
- *   - For decoding, call avcodec_send_packet() to give the decoder raw
- *     compressed data in an AVPacket.
- *   - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
- *     containing uncompressed audio or video.
- *
- *   In both cases, it is recommended that AVPackets and AVFrames are
- *   refcounted, or libavcodec might have to copy the input data. (libavformat
- *   always returns refcounted AVPackets, and av_frame_get_buffer() allocates
- *   refcounted AVFrames.)
- * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
- *   functions and process their output:
- *   - For decoding, call avcodec_receive_frame(). On success, it will return
- *     an AVFrame containing uncompressed audio or video data.
- *   - For encoding, call avcodec_receive_packet(). On success, it will return
- *     an AVPacket with a compressed frame.
- *
- *   Repeat this call until it returns AVERROR(EAGAIN) or an error. The
- *   AVERROR(EAGAIN) return value means that new input data is required to
- *   return new output. In this case, continue with sending input. For each
- *   input frame/packet, the codec will typically return 1 output frame/packet,
- *   but it can also be 0 or more than 1.
- *
- * At the beginning of decoding or encoding, the codec might accept multiple
- * input frames/packets without returning a frame, until its internal buffers
- * are filled. This situation is handled transparently if you follow the steps
- * outlined above.
- *
- * In theory, sending input can result in EAGAIN - this should happen only if
- * not all output was received. You can use this to structure alternative decode
- * or encode loops other than the one suggested above. For example, you could
- * try sending new input on each iteration, and try to receive output if that
- * returns EAGAIN.
- *
- * End of stream situations. These require "flushing" (aka draining) the codec,
- * as the codec might buffer multiple frames or packets internally for
- * performance or out of necessity (consider B-frames).
- * This is handled as follows:
- * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
- *   or avcodec_send_frame() (encoding) functions. This will enter draining
- *   mode.
- * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
- *   (encoding) in a loop until AVERROR_EOF is returned. The functions will
- *   not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
- * - Before decoding can be resumed again, the codec has to be reset with
- *   avcodec_flush_buffers().
- *
- * Using the API as outlined above is highly recommended. But it is also
- * possible to call functions outside of this rigid schema. For example, you can
- * call avcodec_send_packet() repeatedly without calling
- * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
- * until the codec's internal buffer has been filled up (which is typically of
- * size 1 per output frame, after initial input), and then reject input with
- * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
- * read at least some output.
- *
- * Not all codecs will follow a rigid and predictable dataflow; the only
- * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
- * one end implies that a receive/send call on the other end will succeed, or
- * at least will not fail with AVERROR(EAGAIN). In general, no codec will
- * permit unlimited buffering of input or output.
- *
- * This API replaces the following legacy functions:
- * - avcodec_decode_video2() and avcodec_decode_audio4():
- *   Use avcodec_send_packet() to feed input to the decoder, then use
- *   avcodec_receive_frame() to receive decoded frames after each packet.
- *   Unlike with the old video decoding API, multiple frames might result from
- *   a packet. For audio, splitting the input packet into frames by partially
- *   decoding packets becomes transparent to the API user. You never need to
- *   feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
- *   no data was read from the packet).
- *   Additionally, sending a flush/draining packet is required only once.
- * - avcodec_encode_video2()/avcodec_encode_audio2():
- *   Use avcodec_send_frame() to feed input to the encoder, then use
- *   avcodec_receive_packet() to receive encoded packets.
- *   Providing user-allocated buffers for avcodec_receive_packet() is not
- *   possible.
- * - The new API does not handle subtitles yet.
- *
- * Mixing new and old function calls on the same AVCodecContext is not allowed,
- * and will result in undefined behavior.
- *
- * Some codecs might require using the new API; using the old API will return
- * an error when calling it. All codecs support the new API.
- *
- * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
- * would be an invalid state, which could put the codec user into an endless
- * loop. The API has no concept of time either: it cannot happen that trying to
- * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
- * later accepts the packet (with no other receive/flush API calls involved).
- * The API is a strict state machine, and the passage of time is not supposed
- * to influence it. Some timing-dependent behavior might still be deemed
- * acceptable in certain cases. But it must never result in both send/receive
- * returning EAGAIN at the same time at any point. It must also absolutely be
- * avoided that the current state is "unstable" and can "flip-flop" between
- * the send/receive APIs allowing progress. For example, it's not allowed that
- * the codec randomly decides that it actually wants to consume a packet now
- * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
- * avcodec_send_packet() call.

- *             When AVCodecContext.refcounted_frames is set to 1, the frame is

-/**
- * Create and return a AVHWFramesContext with values adequate for hardware
- * decoding. This is meant to get called from the get_format callback, and is
- * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
- * This API is for decoding with certain hardware acceleration modes/APIs only.
- *
- * The returned AVHWFramesContext is not initialized. The caller must do this
- * with av_hwframe_ctx_init().
- *
- * Calling this function is not a requirement, but makes it simpler to avoid
- * codec or hardware API specific details when manually allocating frames.
- *
- * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
- * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
- * it unnecessary to call this function or having to care about
- * AVHWFramesContext initialization at all.
- *
- * There are a number of requirements for calling this function:
- *
- * - It must be called from get_format with the same avctx parameter that was
- *   passed to get_format. Calling it outside of get_format is not allowed, and
- *   can trigger undefined behavior.
- * - The function is not always supported (see description of return values).
- *   Even if this function returns successfully, hwaccel initialization could
- *   fail later. (The degree to which implementations check whether the stream
- *   is actually supported varies. Some do this check only after the user's
- *   get_format callback returns.)
- * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
- *   user decides to use a AVHWFramesContext prepared with this API function,
- *   the user must return the same hw_pix_fmt from get_format.
- * - The device_ref passed to this function must support the given hw_pix_fmt.
- * - After calling this API function, it is the user's responsibility to
- *   initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
- *   and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
- *   before returning from get_format (this is implied by the normal
- *   AVCodecContext.hw_frames_ctx API rules).
- * - The AVHWFramesContext parameters may change every time time get_format is
- *   called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
- *   you are inherently required to go through this process again on every
- *   get_format call.
- * - It is perfectly possible to call this function without actually using
- *   the resulting AVHWFramesContext. One use-case might be trying to reuse a
- *   previously initialized AVHWFramesContext, and calling this API function
- *   only to test whether the required frame parameters have changed.
- * - Fields that use dynamically allocated values of any kind must not be set
- *   by the user unless setting them is explicitly allowed by the documentation.
- *   If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
- *   the new free callback must call the potentially set previous free callback.
- *   This API call may set any dynamically allocated fields, including the free
- *   callback.
- *
- * The function will set at least the following fields on AVHWFramesContext
- * (potentially more, depending on hwaccel API):
- *
- * - All fields set by av_hwframe_ctx_alloc().
- * - Set the format field to hw_pix_fmt.
- * - Set the sw_format field to the most suited and most versatile format. (An
- *   implication is that this will prefer generic formats over opaque formats
- *   with arbitrary restrictions, if possible.)
- * - Set the width/height fields to the coded frame size, rounded up to the
- *   API-specific minimum alignment.
- * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
- *   field to the number of maximum reference surfaces possible with the codec,
- *   plus 1 surface for the user to work (meaning the user can safely reference
- *   at most 1 decoded surface at a time), plus additional buffering introduced
- *   by frame threading. If the hwaccel does not require pre-allocation, the
- *   field is left to 0, and the decoder will allocate new surfaces on demand
- *   during decoding.
- * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
- *   hardware API.
- *
- * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
- * with basic frame parameters set.
- *
- * The function is stateless, and does not change the AVCodecContext or the
- * device_ref AVHWDeviceContext.
- *
- * @param avctx The context which is currently calling get_format, and which
- *              implicitly contains all state needed for filling the returned
- *              AVHWFramesContext properly.
- * @param device_ref A reference to the AVHWDeviceContext describing the device
- *                   which will be used by the hardware decoder.
- * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
- * @param out_frames_ref On success, set to a reference to an _uninitialized_
- *                       AVHWFramesContext, created from the given device_ref.
- *                       Fields will be set to values required for decoding.
- *                       Not changed if an error is returned.
- * @return zero on success, a negative value on error. The following error codes
- *         have special semantics:
- *      AVERROR(ENOENT): the decoder does not support this functionality. Setup
- *                       is always manual, or it is a decoder which does not
- *                       support setting AVCodecContext.hw_frames_ctx at all,
- *                       or it is a software format.
- *      AVERROR(EINVAL): it is known that hardware decoding is not supported for
- *                       this configuration, or the device_ref is not supported
- *                       for the hwaccel referenced by hw_pix_fmt.

- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
-  This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
-  0. Additional Definitions.
-
-  As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
-  "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
-  An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
-  A "Combined Work" is a work produced by combining or linking an
-Application with the Library.  The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
-  The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
-  The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
-  1. Exception to Section 3 of the GNU GPL.
-
-  You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
-  2. Conveying Modified Versions.
-
-  If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
-   a) under this License, provided that you make a good faith effort to
-   ensure that, in the event an Application does not supply the
-   function or data, the facility still operates, and performs
-   whatever part of its purpose remains meaningful, or
-
-   b) under the GNU GPL, with none of the additional permissions of
-   this License applicable to that copy.
-
-  3. Object Code Incorporating Material from Library Header Files.
-
-  The object code form of an Application may incorporate material from
-a header file that is part of the Library.  You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
-   a) Give prominent notice with each copy of the object code that the
-   Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the object code with a copy of the GNU GPL and this license
-   document.
-
-  4. Combined Works.
-
-  You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
-   a) Give prominent notice with each copy of the Combined Work that
-   the Library is used in it and that the Library and its use are
-   covered by this License.
-
-   b) Accompany the Combined Work with a copy of the GNU GPL and this license
-   document.
-
-   c) For a Combined Work that displays copyright notices during
-   execution, include the copyright notice for the Library among
-   these notices, as well as a reference directing the user to the
-   copies of the GNU GPL and this license document.
-
-   d) Do one of the following:
-
-       0) Convey the Minimal Corresponding Source under the terms of this
-       License, and the Corresponding Application Code in a form
-       suitable for, and under terms that permit, the user to
-       recombine or relink the Application with a modified version of
-       the Linked Version to produce a modified Combined Work, in the
-       manner specified by section 6 of the GNU GPL for conveying
-       Corresponding Source.
-
-       1) Use a suitable shared library mechanism for linking with the
-       Library.  A suitable mechanism is one that (a) uses at run time
-       a copy of the Library already present on the user's computer
-       system, and (b) will operate properly with a modified version
-       of the Library that is interface-compatible with the Linked
-       Version.
-
-   e) Provide Installation Information, but only if you would otherwise
-   be required to provide such information under section 6 of the
-   GNU GPL, and only to the extent that such information is
-   necessary to install and execute a modified version of the
-   Combined Work produced by recombining or relinking the
-   Application with a modified version of the Linked Version. (If
-   you use option 4d0, the Installation Information must accompany
-   the Minimal Corresponding Source and Corresponding Application
-   Code. If you use option 4d1, you must provide the Installation
-   Information in the manner specified by section 6 of the GNU GPL
-   for conveying Corresponding Source.)
-
-  5. Combined Libraries.
-
-  You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
-   a) Accompany the combined library with a copy of the same work based
-   on the Library, uncombined with any other library facilities,
-   conveyed under the terms of this License.
-
-   b) Give prominent notice with the combined library that part of it
-   is a work based on the Library, and explaining where to find the
-   accompanying uncombined form of the same work.
-
-  6. Revised Versions of the GNU Lesser General Public License.
-
-  The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
-  Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
-  If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-/**
- * @ingroup libavc
- * @defgroup lavc_encdec send/receive encoding and decoding API overview
- * @{
- *
- * The avcodec_send_packet()/avcodec_receive_frame()/avcodec_send_frame()/
- * avcodec_receive_packet() functions provide an encode/decode API, which
- * decouples input and output.
- *
- * The API is very similar for encoding/decoding and audio/video, and works as
- * follows:
- * - Set up and open the AVCodecContext as usual.
- * - Send valid input:
- *   - For decoding, call avcodec_send_packet() to give the decoder raw
- *     compressed data in an AVPacket.
- *   - For encoding, call avcodec_send_frame() to give the encoder an AVFrame
- *     containing uncompressed audio or video.
- *
- *   In both cases, it is recommended that AVPackets and AVFrames are
- *   refcounted, or libavcodec might have to copy the input data. (libavformat
- *   always returns refcounted AVPackets, and av_frame_get_buffer() allocates
- *   refcounted AVFrames.)
- * - Receive output in a loop. Periodically call one of the avcodec_receive_*()
- *   functions and process their output:
- *   - For decoding, call avcodec_receive_frame(). On success, it will return
- *     an AVFrame containing uncompressed audio or video data.
- *   - For encoding, call avcodec_receive_packet(). On success, it will return
- *     an AVPacket with a compressed frame.
- *
- *   Repeat this call until it returns AVERROR(EAGAIN) or an error. The
- *   AVERROR(EAGAIN) return value means that new input data is required to
- *   return new output. In this case, continue with sending input. For each
- *   input frame/packet, the codec will typically return 1 output frame/packet,
- *   but it can also be 0 or more than 1.
- *
- * At the beginning of decoding or encoding, the codec might accept multiple
- * input frames/packets without returning a frame, until its internal buffers
- * are filled. This situation is handled transparently if you follow the steps
- * outlined above.
- *
- * In theory, sending input can result in EAGAIN - this should happen only if
- * not all output was received. You can use this to structure alternative decode
- * or encode loops other than the one suggested above. For example, you could
- * try sending new input on each iteration, and try to receive output if that
- * returns EAGAIN.
- *
- * End of stream situations. These require "flushing" (aka draining) the codec,
- * as the codec might buffer multiple frames or packets internally for
- * performance or out of necessity (consider B-frames).
- * This is handled as follows:
- * - Instead of valid input, send NULL to the avcodec_send_packet() (decoding)
- *   or avcodec_send_frame() (encoding) functions. This will enter draining
- *   mode.
- * - Call avcodec_receive_frame() (decoding) or avcodec_receive_packet()
- *   (encoding) in a loop until AVERROR_EOF is returned. The functions will
- *   not return AVERROR(EAGAIN), unless you forgot to enter draining mode.
- * - Before decoding can be resumed again, the codec has to be reset with
- *   avcodec_flush_buffers().
- *
- * Using the API as outlined above is highly recommended. But it is also
- * possible to call functions outside of this rigid schema. For example, you can
- * call avcodec_send_packet() repeatedly without calling
- * avcodec_receive_frame(). In this case, avcodec_send_packet() will succeed
- * until the codec's internal buffer has been filled up (which is typically of
- * size 1 per output frame, after initial input), and then reject input with
- * AVERROR(EAGAIN). Once it starts rejecting input, you have no choice but to
- * read at least some output.
- *
- * Not all codecs will follow a rigid and predictable dataflow; the only
- * guarantee is that an AVERROR(EAGAIN) return value on a send/receive call on
- * one end implies that a receive/send call on the other end will succeed, or
- * at least will not fail with AVERROR(EAGAIN). In general, no codec will
- * permit unlimited buffering of input or output.
- *
- * This API replaces the following legacy functions:
- * - avcodec_decode_video2() and avcodec_decode_audio4():
- *   Use avcodec_send_packet() to feed input to the decoder, then use
- *   avcodec_receive_frame() to receive decoded frames after each packet.
- *   Unlike with the old video decoding API, multiple frames might result from
- *   a packet. For audio, splitting the input packet into frames by partially
- *   decoding packets becomes transparent to the API user. You never need to
- *   feed an AVPacket to the API twice (unless it is rejected with AVERROR(EAGAIN) - then
- *   no data was read from the packet).
- *   Additionally, sending a flush/draining packet is required only once.
- * - avcodec_encode_video2()/avcodec_encode_audio2():
- *   Use avcodec_send_frame() to feed input to the encoder, then use
- *   avcodec_receive_packet() to receive encoded packets.
- *   Providing user-allocated buffers for avcodec_receive_packet() is not
- *   possible.
- * - The new API does not handle subtitles yet.
- *
- * Mixing new and old function calls on the same AVCodecContext is not allowed,
- * and will result in undefined behavior.
- *
- * Some codecs might require using the new API; using the old API will return
- * an error when calling it. All codecs support the new API.
- *
- * A codec is not allowed to return AVERROR(EAGAIN) for both sending and receiving. This
- * would be an invalid state, which could put the codec user into an endless
- * loop. The API has no concept of time either: it cannot happen that trying to
- * do avcodec_send_packet() results in AVERROR(EAGAIN), but a repeated call 1 second
- * later accepts the packet (with no other receive/flush API calls involved).
- * The API is a strict state machine, and the passage of time is not supposed
- * to influence it. Some timing-dependent behavior might still be deemed
- * acceptable in certain cases. But it must never result in both send/receive
- * returning EAGAIN at the same time at any point. It must also absolutely be
- * avoided that the current state is "unstable" and can "flip-flop" between
- * the send/receive APIs allowing progress. For example, it's not allowed that
- * the codec randomly decides that it actually wants to consume a packet now
- * instead of returning a frame, after it just returned AVERROR(EAGAIN) on an
- * avcodec_send_packet() call.

-     * - sample_rate, channel_layout, nb_samples (audio only)
-     * Their values may differ from the corresponding values in
-     * AVCodecContext. This callback must use the frame values, not the codec
-     * context values, to calculate the required buffer size.
-     *
-     * This callback must fill the following fields in the frame:
-     * - data[]
-     * - linesize[]
-     * - extended_data:
-     *   * if the data is planar audio with more than 8 channels, then this

-     *     extended_data must be allocated with av_malloc() and will be freed in
-     *     av_frame_unref().
-     *   * otherwise extended_data must point to data
-     * - buf[] must contain one or more pointers to AVBufferRef structures. Each of

-     *   is, one AVBufferRef for each allocated chunk of memory, not necessarily one
-     *   AVBufferRef per data[] entry. See: av_buffer_create(), av_buffer_alloc(),
-     *   and av_buffer_ref().
-     * - extended_buf and nb_extended_buf must be allocated with av_malloc() by
-     *   this callback and filled with the extra buffers if there are more

-     * If AV_CODEC_CAP_DR1 is not set then get_buffer2() must call
-     * avcodec_default_get_buffer2() instead of providing buffers allocated by
-     * some other means.
-     *
-     * Each data plane must be aligned to the maximum required by the target
-     * CPU.

-     * avcodec_align_dimensions2() should be used to find the required width and
-     * height, as they normally need to be rounded up to the next multiple of 16.
-     *
-     * Some decoders do not support linesizes changing between frames.
-     *
-     * If frame multithreading is used and thread_safe_callbacks is set,
-     * this callback may be called from a different thread, but not from more
-     * than one at once. Does not need to be reentrant.

-     * to a smaller value in the output frame.

-/**
- * Create and return a AVHWFramesContext with values adequate for hardware
- * decoding. This is meant to get called from the get_format callback, and is
- * a helper for preparing a AVHWFramesContext for AVCodecContext.hw_frames_ctx.
- * This API is for decoding with certain hardware acceleration modes/APIs only.
- *
- * The returned AVHWFramesContext is not initialized. The caller must do this
- * with av_hwframe_ctx_init().
- *
- * Calling this function is not a requirement, but makes it simpler to avoid
- * codec or hardware API specific details when manually allocating frames.
- *
- * Alternatively to this, an API user can set AVCodecContext.hw_device_ctx,
- * which sets up AVCodecContext.hw_frames_ctx fully automatically, and makes
- * it unnecessary to call this function or having to care about
- * AVHWFramesContext initialization at all.
- *
- * There are a number of requirements for calling this function:
- *
- * - It must be called from get_format with the same avctx parameter that was
- *   passed to get_format. Calling it outside of get_format is not allowed, and
- *   can trigger undefined behavior.
- * - The function is not always supported (see description of return values).
- *   Even if this function returns successfully, hwaccel initialization could
- *   fail later. (The degree to which implementations check whether the stream
- *   is actually supported varies. Some do this check only after the user's
- *   get_format callback returns.)
- * - The hw_pix_fmt must be one of the choices suggested by get_format. If the
- *   user decides to use a AVHWFramesContext prepared with this API function,
- *   the user must return the same hw_pix_fmt from get_format.
- * - The device_ref passed to this function must support the given hw_pix_fmt.
- * - After calling this API function, it is the user's responsibility to
- *   initialize the AVHWFramesContext (returned by the out_frames_ref parameter),
- *   and to set AVCodecContext.hw_frames_ctx to it. If done, this must be done
- *   before returning from get_format (this is implied by the normal
- *   AVCodecContext.hw_frames_ctx API rules).
- * - The AVHWFramesContext parameters may change every time time get_format is
- *   called. Also, AVCodecContext.hw_frames_ctx is reset before get_format. So
- *   you are inherently required to go through this process again on every
- *   get_format call.
- * - It is perfectly possible to call this function without actually using
- *   the resulting AVHWFramesContext. One use-case might be trying to reuse a
- *   previously initialized AVHWFramesContext, and calling this API function
- *   only to test whether the required frame parameters have changed.
- * - Fields that use dynamically allocated values of any kind must not be set
- *   by the user unless setting them is explicitly allowed by the documentation.
- *   If the user sets AVHWFramesContext.free and AVHWFramesContext.user_opaque,
- *   the new free callback must call the potentially set previous free callback.
- *   This API call may set any dynamically allocated fields, including the free
- *   callback.
- *
- * The function will set at least the following fields on AVHWFramesContext
- * (potentially more, depending on hwaccel API):
- *
- * - All fields set by av_hwframe_ctx_alloc().
- * - Set the format field to hw_pix_fmt.
- * - Set the sw_format field to the most suited and most versatile format. (An
- *   implication is that this will prefer generic formats over opaque formats
- *   with arbitrary restrictions, if possible.)
- * - Set the width/height fields to the coded frame size, rounded up to the
- *   API-specific minimum alignment.
- * - Only _if_ the hwaccel requires a pre-allocated pool: set the initial_pool_size
- *   field to the number of maximum reference surfaces possible with the codec,
- *   plus 1 surface for the user to work (meaning the user can safely reference
- *   at most 1 decoded surface at a time), plus additional buffering introduced
- *   by frame threading. If the hwaccel does not require pre-allocation, the
- *   field is left to 0, and the decoder will allocate new surfaces on demand
- *   during decoding.
- * - Possibly AVHWFramesContext.hwctx fields, depending on the underlying
- *   hardware API.
- *
- * Essentially, out_frames_ref returns the same as av_hwframe_ctx_alloc(), but
- * with basic frame parameters set.
- *
- * The function is stateless, and does not change the AVCodecContext or the
- * device_ref AVHWDeviceContext.
- *
- * @param avctx The context which is currently calling get_format, and which
- *              implicitly contains all state needed for filling the returned
- *              AVHWFramesContext properly.
- * @param device_ref A reference to the AVHWDeviceContext describing the device
- *                   which will be used by the hardware decoder.
- * @param hw_pix_fmt The hwaccel format you are going to return from get_format.
- * @param out_frames_ref On success, set to a reference to an _uninitialized_
- *                       AVHWFramesContext, created from the given device_ref.
- *                       Fields will be set to values required for decoding.
- *                       Not changed if an error is returned.
- * @return zero on success, a negative value on error. The following error codes
- *         have special semantics:
- *      AVERROR(ENOENT): the decoder does not support this functionality. Setup
- *                       is always manual, or it is a decoder which does not
- *                       support setting AVCodecContext.hw_frames_ctx at all,
- *                       or it is a software format.
- *      AVERROR(EINVAL): it is known that hardware decoding is not supported for
- *                       this configuration, or the device_ref is not supported
- *                       for the hwaccel referenced by hw_pix_fmt.
