Andreas Rheinhardt 89ca63cc9c avcodec/mpegpicture: Split ff_alloc_picture() into check and alloc part 
ff_alloc_picture() currently does two things: It checks the
consistency of the linesize (which should not be necessary, but is)
and it allocates certain buffers. (It does not actually allocate
the picture buffers, so its name is misleading.)
This commit splits it into two separate functions. The rationale
for this is that for the encoders, every picture needs its linesizes
checked, but not every picture needs these extra buffers.

  • 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.
