23 OCT 2025 - We are back! If you have been following us over the last few years, you will know that the last 2 months have been rough. We website was practically not loading. Sorry for the mess. We are back though and everything should run smoothly now. New servers. Updated domains. And new owners. We invite you all to start uploading torrents again!
FOURCC: AV02
AVCodecID: AV2
Yes this is actual (experimental) AV2. No player that I'm aware of can decode it. No player can handle the AV2 codec ID. Only the AVM aomdec reference decoder can read it.
This was encoded using the AVM master branch: https://gitlab.com/AOMediaCodec/avm
This is primarily for people who want to test their utilities or workflows with an actual AV2 file.
If you want to get the video out of the file:
1) Build the avm master branch: https://gitlab.com/AOMediaCodec/avm
2) Bin/Hex edit the file to change the "AV2" (string search for it) codec ID to "AV1"(nano can do it) so the utilities don't choke on it.
3)
```
mkvextract [infile] tracks 0:/media/SMRE/av2.ivf
```
4)
```
./avm_build/aomdec -k av2.ivf --rawvideo --output-bit-depth=8 | ffmpeg -s 854x480 -framerate 24000/1001 -f rawvideo -i pipe: -vcodec libx264 -qp 0 -preset medium -an -sn [h264_lossless_outfile] -threads 16
```
Encoding parameters (AV2/AVM is **incredibly** slow):
```
ffmpeg -i [infile] -strict -2 -vf scale=854:480 -f yuv4mpegpipe - | ./avm_build/aomenc --threads=8 --row-mt=1 --cpu-used=6 --end-usage=q --qp=27 --enable-fwd-kf=1 --aq-mode=1 --lag-in-frames=48 --auto-alt-ref=1 --bit-depth=8 --sb-size=64 --arnr-strength=0 --arnr-maxframes=3 --enable-restoration=0 --deltaq-mode=0 -o [.ivf outfile] -
