James Almer 02cf239196 avformat: call AVOutputFormat->deinit() when freeing the context 
Despite the doxy stating that it's called when the muxer is destroyed,
this was not true in practice. It's only called by av_write_trailer()
and on init() failure.

An AVFormatContext may be closed without writing the trailer if errors
ocurred while muxing packets, so in order to prevent memory leaks, it
should effectively be called when freeing the muxer.

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.
