V4L2_CID_MPEG_MFC51_VIDEO_FORCE_FRAME_TYPE not working with AV1 encoder

[oviano]

So I can see this was actually reported back in 2022:

AV1 using jetson orin forceIDR() and bitrate change not working?

int NvVideoEncoder::forceIDR() { struct v4l2_ext_control control; struct v4l2_ext_controls ctrls; RETURN_ERROR_IF_FORMATS_NOT_SET(); memset(&control, 0, sizeof(control)); memset(&ctrls, 0, sizeof(ctrls)); ctrls.count = 1; ctrls.controls = &control; ctrls.ctrl_class = V4L2_CTRL_CLASS_MPEG; control.id = V4L2_CID_MPEG_MFC51_VIDEO_FORCE_FRAME_TYPE; CHECK_V4L2_RETURN(setExtControls(ctrls), "Forcing IDR"); } Same code work for h264/hevc?

That issue was “closed” but it’s not clear the problem was solved. Certainly the “solution” refers to JP 5.1.1, but I am already using 5.1.1.

If it has since been solved in 5.1.2 or 6.0 I can’t find anything in the release notes - can someone confirm if this issue is still active or, if it has been solved, which version the fix appears in?

Also, further investigation shows that the issue is that V4L2_CID_MPEG_MFC41_VIDEO_FORCE_FRAME_TYPE does indeed force an I-frame but it is not an IDR frame/key frame. This is shown by the increased size of the produced packets. I tried treating them as key frames after a previous discontinuity but this just produced corruption on the screen when decoding, so they were obviously not IDR frames.

Thanks!
