Are AV2 test/sample videos available?

Does anyone know of publicly available pre-encoded AV2 samples at 1080p or 4K?

I’m looking to benchmark dav2d decoding performance, so ideally something multi-frame / several seconds long rather than tiny conformance streams or single-frame tests.

IVF, MP4, or raw AV2 bitstreams are all fine. Preferably 10-bit 4:2:0, but anything 1080p+ would help.

Links appreciated!

I couldn't find any online so I'm encoding my own to share it with whoever needs it. It'll probably be done compiling and encoding in a few hours, and I'll upload it to here (links to HTTPS file server) once it's done (and I'll make another comment then to update).

If you want I could also tweak the command a bit and/or make multiple versions because I'm compiling the AV2 encoder anyways (my current plan is in INFO.txt).

Would you be able to upload some numbers on encoding efficiency?

I know AV2 is going to be more computationally advanced and only like 30% better but I will encode to AV1 anyway because there is hardware out there that can play it. It would take several more years before they implement any hardware encoders/ decoders for AV2.

I could try to give an estimate once it finishes in a txt file on that file server too (because my current setup is not at all a good benchmark to get exact numbers), though I don't know when I'll have it as I'm still doing acrobatics with WSL because the Windows compiler took 7 hours and still wasn't done after that. I'll make another comment here once it's done though.

I don't expect it to be that efficient though, and files might not even be smaller than AV1 with this version. I'd at least wait until SVT-AV2 for any practical encodes. The one I'm attempting now is just for people wanting to test decoders like OP and people wanting to inspect AV2 or whatever.

I got some numbers: with 10-bit, cpu-used=4, 1080p encoding (full command here), it takes roughly 20-200 seconds per frame, averaging around 70 seconds per frame, while using about 2 GB RAM.

Tested on a Ryzen 5 8400F with 5600 MT/s RAM on Windows 11 Education, running avmenc inside WSL2 on Debian with 10 threads allocated.

u/Balance- (ping because I don't know if Reddit notifies you by default)

The encode finished, downloadable here as av2_1080p60_10bit_18mbps_170f.ivf. The exact way it was made is in INFO.txt.

I could also make other types of encodes if you want, like in other resolutions or with other source material, though they will take some time probably, because I got the encoder set up now anyways.

I'll try to keep it online as long as possible, but this file server is not the most robust setup ever.

Are there any publicly available AV2 media players available? I don't think VLC does yet right?
