The source code has been modified in the following ways:

1. Changed the definition of AV_NUM_DATA_POINTERS from 8 to 16 in libavutil/frame.h, to support up to 16 streams
   of audio.
2. Added a null variable check in libavutil/wchar_filename.h, to protect against a possible crash involving
   wide-latin-character file names.
