Rostislav Pehlivanov 3c99523a28 opus_pvq_search: split functions into exactness and only use the exact if its faster 
This splits the asm function into exact and non-exact version. The exact
version is as fast or faster on newer CPUs (which EXTERNAL_AVX_FAST describes
well) whilst the non-exact version is faster than the exact on older CPUs.

Also fixes yasm compilation which doesn't accept !cpuflags(avx) syntax.

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.
  • ffserver is a multimedia streaming server for live broadcasts.
  • Additional small tools such as aviocat, ismindex and qt-faststart.

Documentation
