Digging in a little, based on similarities in the readme and the mailing list being the same, it appears to be related to Intel[1]. Looks to be an extension of Intel's Visual Cloud Computing efforts[2].

Edit: Feeling dumb, but confirmed, Intel is also in the license[3] :)

those are some steep requirements - 48 GB RAM?

For 112 cores, that's only 2.333333 gigs per core

That is still way too much, a 4k RGB 8 bit frame is about 25 MB, and many frames could be operated on at once, but I doubt the equivalent of around 2000 uncompressed 4k frames (less depending on 10 bit color) need to be in memory all at once.

In practice, do the RAM requirements for this software go down with fewer cores/threads?

This is an Intel project, showing off their work on AV1 encoding.

I love it when reposts get traction https://news.ycombinator.com/item?id=19072647

Anyway can't wait to test this. Right now my library still is mainly h264. Wanted to get everything to vp9 a while back which was too slow, then tried hevc which was faster, but not really satisfactorily either. Hope this will get down to vp9 encoding speed so that it's at least feasible...

I was dissapointed that your submission hadn’t caught traction, so I reposted it with “Intel releases ...” in the title because for me that was the newsworthy bit. I was interested in what the community had to say about this Intel code being optimized for Intel cpu’s.

It seems the mods changed the title again though, and reading the comments people seem to be surprised that this is Intel’s.

Yeah it's sad that this thing happens from time to time, but man I'm glad that now people are actually talking aboujt it because I'm psyched :)

I was waiting for a good encoder to show up and this seems like a step in the right direction
