VP8 codec SDK "Aylesbury" released

[Posted November 3, 2010 by jake]

The VP8 codec SDK—the codec used by WebM—has been released. Also known as libvpx, "Aylesbury" is the first of planned quarterly releases.

For Aylesbury the theme was faster decoder, better encoder. We used our May 19, 2010 launch release of libvpx as the benchmark. We're very happy with the results (see graphs below):

20-40% (average 28%) improvement in libvpx decoder speed
Over 7% overall PSNR improvement (6.3% SSIM) in VP8 "best" quality encoding mode, and up to 60% improvement on very noisy, still or slow moving source video.
