Andreas Rheinhardt 98060a198e avcodec/vc1dec: Fix memleak upon allocation error 
ff_vc1_decode_init_alloc_tables() had one error path that forgot to free
already allocated buffers; these would then be overwritten on the next
allocation attempt (or they would just not be freed in case this
happened during init, as the decoders for which it is used do not have
the FF_CODEC_CAP_INIT_CLEANUP set).

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • 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.
