<DIV>> Hi,</DIV>
<DIV>> I see your blog, you just compare filesize, no PSNR, SSIM and
more.</DIV>
<DIV> </DIV>
<DIV>Hi, I don't compare PSNR because it's inconsistent with human eye </DIV>
<DIV>perception. Even the structural similarity index is not as good as human
</DIV>
<DIV>eyes.</DIV>
<DIV> </DIV>
<DIV>> For decode speed, I think H264 optimize more than 10 years, but H265
is</DIV>
<DIV>> shorter time, it is not a big problem.</DIV>
<DIV> </DIV>
<DIV>I was serious, I'm impressed by the current encoding/decoding speeds.
</DIV>
<DIV>Especially compared to VP9 which seems to encode using a wooden abacus
</DIV>
<DIV>(~1.4 minutes per frame).</DIV>
<DIV> </DIV>
<DIV>> btw: There have some decoder double speed than ffmpeg.</DIV>
<DIV>> Best regards,</DIV>
<DIV>> Min</DIV>
<DIV> </DIV>
<DIV>Like Mainconcept? I don't like proprietary software.</DIV>
