Is AV1 supported by hardware yet? Like TV, phones etc?
@icedquinn
Second question, is AV1 actually that much better than h265 or even h264 to where the encoding slowdown is worth it?
I've checked out h265 a few times, and every time the slowdown compared to h264 was ridiculous and not worth it for most content. Whereas, h264 was so good compared to it's predecessor divx/xvid, that it's worth using at even crazy low resolutions.
this is with 8 cores cooking a pizza tho.
@icedquinn
Faster than vp9 is good (by any margin), but only 30% smaller than h265 is not that impressive for 2x slower. Not impressive for me anyway, because h265 itself is not an amazing benchmark to compare against.
@icedquinn
h265 and whatever comes after it are probably both shit. I remember trying to read into what h265 had different over h264, and it was mostly how big the grid of pixels that it was analyzing was, and how it would merge them as a single color if they were close enough. Basically h265 compresses 4k video better by creating more blockiness than h264. Not impressive at all.
or something.
i looked in to the bitstream and the spec is massive bordering on general computation device.
@icedquinn
All video codecs have motion prediction to some degree. Maybe AV1 has a different algorithm that is better, but that's a basic video codec feature since divx/xvid days (it's what causes that weird color smear glitch when video gets corrupted).
As for flexible chunking, I don't think that's a new thing either, although I might be confusing what it's referring to. Haven't looked into video codecs for so long, that I've forgotten some of the jargon.
@icedquinn
The next big video codec to gain mainstream attention won't be open source/patent free, no matter how good it is. Even if av1 is significantly better than h266 (or whatever comes after h265) it won't matter if av1 doesn't get the lobbying behind it.
av1 was kinda always about getting off the plantation more than anything though.
h265 and the next is about cramming super hd deluxe titty micropore cam on to a spinny disk.
