Andreas Rheinhardt 0fcf74f435 avformat/oggenc: Don't free AVStream's priv_data, fix memleak
For FLAC, Speex, Opus and VP8 the Ogg muxer allocates two buffers
for building the headers: The first for extradata in an Ogg-specific
format and the second contains a Vorbiscomment. These buffers are
reachable via pointers in the corresponding AVStream's priv_data.

If an error happens during building the headers, the AVStream's
priv_data would be freed. This is pointless in general as it would be
freed generically anyway, but here it is actively harmful: If the second
of the aforementioned allocations fails, the first buffer would leak
upon freeing priv_data.

This commit stops freeing priv_data manually, which allows the muxer to
properly clean up in the deinit function.

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.
