Indeed ^^

I've been looking forward to trying out Socionext's FPGA AV1 encoder

It's neat to know something like this exist, however it's not really feasible for my usage case due to a processing time / bandwidth required point of view. I need local hardware, ahh... beggars can't be choosers and all that

And a bit of a rando question, not sure whether this is ffmpeg specific or VPX/VP9 specific.

2-pass CRF is nice, I like it, and it actually seems to run a tad bit faster than a traditional 2pass, which bringing potentially better compression. However I'm also interesting in vbv/constained buffer values. I have found examples of how to do such in a regular 2-pass encode, but I cannot find anything that says whether it will/won't work if you try it with a 2pass CRF encode.

Can anyone elaborate on whether this would work, or how I could at least verify it with some test cases ? I'm worried if I specify anything other than b:v 0 it will fall back to some other mode, or not generally drop the bitrate below b:v X even if it can go lower than X

Intel Gen12/Xe GPU in Tiger Lake supports VP9 12-bit & 12-bit 4:4:4 hardware decoding.
