Gyan Doshi 56419428a8 avcodec/mfenc: set variable frame size flag. 
Default avctx->frame_size is 0 which led to init failure for
audio MediaFoundation encoders since 827d6fe73d.

The MF audio encoders accept variable frame size input buffers.

Fixes #9802

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
