ERROR: NULL VI channel received on AGX Xavier

Hello,

Just to provide an update, I did resolve the issue preventing me from collecting raw images. Specifically, the impact of the null pointer exceptions.

It appears there is an issue caused by the vi_channel_error_recover function in vi5_fops.c even as of R35.5.0. Whenever the CSI subdev is unable to close a stream due to the channel pointer becoming null, the channel capture_state remains in CAPTURE_ERROR, and the logic in vi5_fops.c prevents it from entering the CAPTURE_GOOD state.

This is probably intentional and needs to be resolved, but it seems that not closing an NVCSI stream upon one error does not prevent collecting additional frames. After making the workaround fix, I think I am able to collect raw frames using v4l2-ctl:

user@tegra-ubuntu:~$ v4l2-ctl -v width=1920,height=1080,pixelformat='GB12' --set-ctrl=bypass_mode=0,frame_rate=30000000 -c sensor_mode=0 --stream-mmap -d 0 --stream-to=video0.raw

I am aware that there are CHANSEL_SHORT_FRAME errors even after boosting clocks, but that is minor for now.

At this point, I would like to be able to do the following:

  1. Optionally, convert the raw capture into an encoded video, given the video format of the sensor

  2. Use nvarguscamerasrc (with the econ provided ISP settings, camera_overrides.isp) to get an encoded video in gstreamer

I am trying the following reference , which has been tested in Jetpack 4.6 with these cameras and confirmed to work:

Unfortunately, I am still receiving the following error according to the Gstreamer console logs:
