Andreas Rheinhardt da44bbefaa avformat/avidec: Fix memleak with embedded GAB2 subtitles 
The code for GAB2 subtitles predates refcounting AVPackets. So in order
to transfer the ownership of a packet's data pkt->data was simply stored
and the packet zeroed; in the end (i.e. in the read_close-function) this
data was then simply freed with av_freep(). This of course leads to a leak
of an AVBufferRef and an AVBuffer. It has been fixed by keeping and
eventually unreferencing the packet's buf instead.

Additionally, the packet is now reset via av_packet_unref().

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.

Documentation
