You asked: This is 1 camera on board and 3 test streams flvmuxed to an rtmp server and recorded locally. Takes all night to crash.
For people looking for a four way streaming and record solution this might be an interesting gstreamer pipeline. Change out the videotestsrc to other cameras. My current version is mixing the onboard and USB cams

Hi marekw63,
In your pipeline, nvcamerasrc and omxh264enc are owned by NVIDIA. If you replace nvcamerasrc with another videotestsrc, do you also observe the issue?

And in the pipeline, the input to omxh264enc is 1280x960p20(combined 4 640x480)?

Hi, I am a few weeks away from getting back to this - thanks for the suggestions though.
I have to try 24.2.1 and then alternate nvidia encoders as you suggest.
