That's an interesting claim. I have to say it doesn't match my experience at all, e.g. when playing VP9 videos on Youtube. Several thoughts: * I'm not sure what the "ffh264" decoder they're talking about is. My understanding is that pretty much everyone is using libx264 for both encoding and decoding. Maybe the latter is more performant? * Using SSIM to pick "equal quality" files will probably not give very accurate results. * SVT-VP9 is, if I'm not mistaken, a hardware encoder. One of the issues with these is that they require some significant tradeoffs to get better speed, so they'll have worse quality than a software encoder at the same bitrate. If you go with software you really pay the price when it comes to encoding time.
