Ruikai Peng bb424927db avformat/sierravmd: fix header read error check 
The header read check stored the comparison result into ret, so read
failures became ret=1 and were treated as success, leaving the VMD header
uninitialized and letting parsing continue with bogus state.

Regression since: ee623a43e3.

  • 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.
