Camera driver works with v4l2-ctl but fails to launch argus_camera

norman_xu · June 4, 2026, 2:02pm

Hi Nvidia team,

We are currently developing a camera driver on JetPack 7.1.

While we can successfully capture frames and verify the frame rate using the v4l2-ctl command, we are running into issues when launching argus_camera (it fails to start).

Here are the details and configuration files for your reference:

hello norman_xu,

it looks like an error reported due to EGL config.
please give it a try to disable preview and shows frame-rate only for issue narrow down,
for instance,
$ gst-launch-1.0 nvarguscamerasrc sensor-id=0 sensor-mode=0 ! 'video/x-raw(memory:NVMM),width=1920, height=1080, framerate=30/1, format=NV12' ! nvvidconv ! fpsdisplaysink text-overlay=0 name=sink_0 video-sink=fakesink sync=0 -v

BTW,
since JetPack 7.2 is available, if that’s possible, please moving forward to have confirmation.

norman_xu · June 5, 2026, 3:21am

It’s fixed, the EGLStream creation failure was caused by wayland, thanks.
