    Ehm, no, 7% or 26% is not "much greater" than a 1.3 (or even a 4.5) times improvement. Saying something is 1.3 times faster is the same as a 30% (or 33.333333% or something similar) improvement.

      My thoughts exactly.
      Michael, can you elaborate on this? Is it a typo?

        and ffmpeg one?

        I know that ffmpeg guy have done an other one which was really fast.
        So what is the winner between ffvp8 and libvpx?

          ffvp8 is only a decoder. The new libvpx release brings lots of encoder improvements.

            I'd be pretty cool if VP8 guys would stop caring about crappy metrics like PSNR for video quality.

              Looks like he wrote it in haste.. A quick click on the link to the blog shows where he got his figures.

              "Best" mode average encoding speed: On x86 processors, Bali runs 4.5x as fast than our initial release and 1.35x faster than Aylesbury.
              "Good" mode average encoding speed: Bali is 2.7x faster than our initial release and 1.4x faster than Aylesbury.
              On ARM platforms with Neon extensions, real-time encoding of video telephony content is 7% faster than Aylesbury on single core ARM Cortex A9, 15% on dual-core and 26% on quad core.
              On the NVidia Tegra2 platform, real time encoding is 21-36% faster than Aylesbury, depending on encoding parameters.
              "Best" mode average quality improved 6.3% over Aylesbury using the PSNR metric.
              "Best" mode average quality improved 6.1% over Aylesbury using the SSIM metric.
              So they're talking about different settings.. Best, good and real-time encoding.
