[Jetpac-5.1.5] Error launching dual cameras with Gstreamer

khang.l4es · June 10, 2025, 2:23pm

Dear Forum,

I have been able to stream dual IMX296 cameras in Jetpack-5.1.2 with 100% stability. However, I migrated to Jetpack-5.1.5 and facing the following error when trying to show dual cameras in a single Gstreamer windows as below :

$ gst-launch-1.0 nvcompositor name=nvcomp sink_0::xpos=0 sink_0::ypos=0 sink_0::width=1280 sink_0::height=720 sink_1::xpos=1280 sink_1::ypos=0 sink_1::width=1280 ! nvvidconv !

The issue also happens while streaming dual cameras over network after a couple of retries, especially if there was a delayabout > 3 seconds btw re-launching Gstreamer command :

If I stopped and started the streaming immediately, the above error seems NOT to happen.

Re-starting the argus daemon did not help. And sometime the system hangs.

Have you ever experienced this?

Best Regards,

Hello @khang.l4es,

A couple of questions:

Do you see any errors on dmesg or over UART while trying camera capture?
Are you able to capture from both cameras independently?
You mentioned that if you restart the camera immediately, the error seems to stop. Does this mean that if you restart camera capture the cameras work as expected over an undetermined period of time ?

best regards,

Could you confirm by two session to launch two cameras without nvcompositor.

Thanks

Hi @ShaneCCC ,

I suppose that the driver of IMX296 needs to be updated for being used with the Jetpack-5.1.5 (I was thinking that it should be straight-forward to move from Jetpack-5.1.2 to Jetpack-5.1.5, however) as I could not reproduce the issue with another camera sensor of which driver is more recent (I ported it back to Jetpack-5.1.5 from Jetpack-6.2).
