Andreas Rheinhardt 6f7d3bde11 avcodec/vp8, vp9: Avoid using VP56mv and VP56Frame in VP8/9 
Instead replace VP56mv by new and identical structures VP8mv and VP9mv.
Also replace VP56Frame by VP8FrameType in vp8.h and use that
in VP8 code. Also remove VP56_FRAME_GOLDEN2, as this has only
been used by VP8, and use VP8_FRAME_ALTREF as replacement for
its usage in VP8 as this is more in line with VP8 verbiage.

This allows to remove all inclusions of vp56.h from everything
that is not VP5/6. This also removes implicit inclusions
of hpeldsp.h, h264chroma.h, vp3dsp.h and vp56dsp.h from all VP8/9
files.

(This also fixes a build issue: If one compiles with -O0 and disables
everything except the VP8-VAAPI encoder, the file containing
ff_vpx_norm_shift is not compiled, yet this is used implicitly
by vp56_rac_gets_nn() which is defined in vp56.h; it is unused
by the VP8-VAAPI encoder and declared as av_unused, yet with -O0
unused noninline functions are not optimized away, leading to
linking failures. With this patch, said function is not included
in vaapi_encode_vp8.c any more.)

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.
