Hey there. I am having a problem that I cannot seem to wrap my head around and need some guidance. I am running a dual camera system on a Jetson Xavier on a JP4.3 and so far it seems that when I run the second camera (the one on /dev/video1) at some point the stream is stuck. If I switch the camer…

Can these two camera working well individually?

Seems so, the cameras are identical and I’ve been running a stream on video0 for 12 hours straight non-stop and it works. As I said, if I physically switch the camera modules so that the second camera is on /dev/video0 it is still working. I only find issues on /dev/video1 Do you have an idea where…

NOMATCH indicates no VI channel is enabled to capture the input stream. Don’t know why it happen suddenly.

We have a similar problem. (JP4.3 + Leopard Images imx334 kit) The camera app captures 3 cameras for about 30-60 seconds and after that we get the same error. NvCapture) Error InvalidState: Free request list is empty! (in /dvs/git/dirty/git-master_linux/camera/capture/nvcapture/capture.c, function…

Hi, were you able to root-cause or work-around the “Error InvalidState: Free request list is empty!” error? I am seeing the same intermittently on my multi-camera system.

No. Have you used a Leopard Imaging imx334 camera or another? I found that on the imx 447 this error does not occur very often.

I’m using another camera. Thanks for sharing your findings, it seems to indicate it might be a driver-related issue.

Did you record captured stream to ssd ? In my case, when I am recording, I get the error faster than when capturing and streaming.

Yes I’m writing to disk as well. Haven’t checked to see how the error rate is affected by writing to disk.

Camera is stuck after a while and I cannot figure out why
