-- `execute` method is overloaded and has an optional delimiter parameter. Delimiter defines how the command string will be split into arguments. 
-When delimiter is not specified the space character is used as the default delimiter. 
-Based on this, if one or more of your command arguments include a space character, in filename path or in `-filter_complex` block, then your command string will be split into invalid arguments and execution will fail.  
-You can fix this error by splitting your command string into array yourself and calling `executeWithArguments` method or using a different delimiter character in your command string and specifying it in the `execute` call.

 - Enabling `ProGuard` on releases older than `v0.2.4` causes linking errors. Please add the following rule inside your `proguard-rules.pro` file to preserve necessary method names and prevent linking errors.
