Andreas Rheinhardt 0154fb43e3 avcodec/mpegvideo: Allocate encoder-only tables in mpegvideo_enc.c 
This commit moves the encoder-only allocations of the tables
owned solely by the main encoder context to mpegvideo_enc.c.
This avoids checks in mpegvideo.c for whether we are dealing
with an encoder; it also improves modularity (if encoders are
disabled, this code will no longer be included in the binary).
And it also avoids having to reset these pointers at the beginning
of ff_mpv_common_init() (in case the dst context is uninitialized,
ff_mpeg_update_thread_context() simply copies the src context
into dst which therefore may contain pointers not owned by it,
but this does not happen for encoders at all).

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.
