Andreas Rheinhardt f89825e60a avcodec/h2645_sei: Factor out freeing common SEI parts 
This commit only factors out freeing the common SEI parts,
not whether the fields indicating whether an SEI is present
shall be reset. H.264 and HEVC differ in this regard
(ff_h264_sei_uninit() really resets, whereas ff_hevc_reset_sei()
only uninits.) and neither actually honours the persistency
as prescribed by the relevant specs.

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 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.

Documentation

The offline documentation is available in the doc/ directory.
