Update libvpx to version 1.4.0

Currently libvpx 1.3.0 is implemented in ffmpeg. Version 1.4.0 of libvpx was released and should now be implemented into ffmpeg. The new version has significant improvements to VP9:

  • Fixes a VP9 bitstream issue in Profile 1. This only affects non-YUV 4:2:0 files.
  • Significant algorithmic improvements to VP9 encoding, support for YUV 4:2:2 and 4:4:4 colorspaces as well as high bit depth (10 and 12 bit).
  • More functions are now optimized for VP9 encoding and decoding.
  • VP9 encodes are faster with multithreaded encoding on by default.
  • VP9 decoder now has two multithreaded modes: tile based and frame based. The encoder now enables these by default to help ensure your encoded content will be able to take advantage of these modes.
  • 64bit support for ARM thanks to intrinsics instead of ARM assembly.

ffmpeg already supports any libvpx version from 1.2.0 onwards.

Simply compile ffmpeg with whichever version of libvpx you need installed in a place where the compiler can link to it.
