Andreas Rheinhardt df6ec7f83b avcodec/bitstream: Consistently treat symbol as VLC_TYPE 
If a static VLC table gets initialized a second time (or concurrently by
two threads) and if said VLC table uses symbols that have the sign bit
of VLC_TYPE (a typedef for int16_t) set, initializing the VLC fails. The
reason is that the type of the symbol in the temporary array is an
uint16_t and so comparing it to the symbol read from the VLC table will
fail, because only the lower 16bits coincide. Said failure triggers an
assert.

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides a mean to alter decoded Audio and Video through chain of 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.
