I am trying to test an IMX477 Camera using the RidgeRun driver and V4L2 with the following command:
v4l2-ctl -d /dev/video0 --stream-mmap
The command hangs and does not produce the expected output with a < representing each frame processed. I do not need to save these frames anywhere as I am just trying to test the sensor + driver. However, the following GStreamer command DOES work just fine and produces a valid MP4.
gst-launch-1.0 -e nvarguscamerasrc sensor-id=0 ! nvvidconv ! nvv4l2h264enc ! h264parse ! qtmux ! filesink location=test_cam1_full.mp4
If I switch the nvarguscamerasrc for nvv4l2camerasrc, I get the same results as the V4L2 command. The following dmesg output appears after the failed v4l2-ctl command:

I am using a custom Yocto image with a custom baseboard. Here is the Linux version info:
[ 0.000000] Linux version 5.10.104-l4t-r35.1+g54ed8db939c5 (oe-user@oe-host) (aarch64-oe4t-linux-gcc (GCC) 11.3.0, GNU ld (GNU Binutils) 2.38.20220708) #1 SMP PREEMPT Thu Mar 9 22:14:31 UTC 2023
Has anyone else seen this behavior or have any advice for further debugging? @DavidSoto-RidgeRun Have any other users of the driver seen anything similar to this?
Thanks!
