Orin NX AV1 encoding limitations

We have successfully tested AV1 streaming from gstreamer to Chrome browser via webrtcbin running on Orin NX 16GB.

Now the problems we are looking to solve:

  1. It works with 2 x 1080p streams at 90 or even 120 fps, but when we switch to 2k / 2712x1538 at 90 fps one stream and 1080p the second, the nvv4l2av1enc does not provide a valid stream anymore, no particular errors in the logs. It works with 2k / 60 fps + 1080p 90 fps tho… According to the datasheet, it should be able to handle it: AV1 / UHP / 4K60 (1) | 4K30 (3) | 1080p60 (6) | 1080p30 (12) 750 MP/S
  2. The encoder does not produce valid keyframes for Chrome browser, so at first PLI, the image freezes forever. How can we debug this further? We tried both profile=0 and 1.

Thank you!

Hi,
For information, do you use Jetpack 6.2? Adn please check if you can replicate it by running a gst-launch-1.0 command. We would like to replicate it on developer kit and investigate further.
