Gstreamer DS 6 on l4t 31.1.1 nvv4l2av1enc does not output IDR FLAGS

Dear support,

nvv4l2av1enc works great but always outputs DELTA_UNIT flags regardless if IDR or not.

Is this a known issue?

AV1 encoder is new so there might be certain issue. We will check this. You may use h264/h265 as a quick solution.

Please help check the source code of av1parse:
gst/videoparsers/gstav1parse.c · master · GStreamer / gst-plugins-bad · GitLab

It marks GST_BUFFER_FLAG_DELTA_UNIT for key frames. So this looks to be expected. It does not have same behavior as H264/h265.
