Andreas Rheinhardt b2866b7216 avcodec/ppc/mpegvideo_altivec: Use correct inter scantable 
This affected the WMV1/2 encoders (but not when running FATE because
the encoding part uses the fastint dct, so this code isn't used
then anyway).

It did not affect anything else, because a) only WMV1/2 use different
scantables, b) ff_msmpeg4_decode_block() (and therefore the WMV1
decoder) already unquantize inter macroblocks as they are parsed
c) the WMV2 decoder does not use the unquantize functions for inter
macroblocks 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
