No, type enter a few times in the dmesg terminal in order to separate previous messages from the ones that will happen now if any.
Then in the other terminal, launch the gst-launch command. If this triggers new messages, just post these.
no messages at all after running the commands.
What about reading each camera separately as above ?
I ask that because your working pipeline doesn’t specify any mode.
I tried using the cameras separately and it just gives me the same errors as before:
WARNING: erroneous pipeline: no element "nvv4l2decoder"
here is a screenshot of the dmesg terminal and me running the commands in putty:
Hmm… Be sure it is nvv4l2decoder, not nvv412decoder.
What gives:
# Test cam1
gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg ! nvv4l2decoder mjpeg=1 ! nvvidconv ! xvimagesink
# Test cam2
gst-launch-1.0 -v v4l2src device=/dev/video1 ! image/jpeg ! nvv4l2decoder mjpeg=1 ! nvvidconv ! xvimagesink
Literally copying and pasting from what you post.
gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg ! nvv4l2decoder mjpeg=1 ! nvvidconv ! xvimagesink
Gives me:
b3ck@belabox:/usr/share/belacoder/pipelines/jetson$ gst-launch-1.0 -v v4l2src device=/dev/video0 ! image/jpeg ! nvv4l2decoder mjpeg=1 ! nvvidconv ! xvimagesink

Please post the output of v4l2-ctl commands above (v4l2-ctl is provided by apt package v4l-utils).
You may also try:

I also have a fresh never touched version of a belabox on another jetson nano and I get this:

I installed gstreamer1.0-tools and got a bunch of info:

Ok, so now retry the pipelines for reading each cam.
I can’t I’m doing this all remotely, so I need to have the person format the SD card and re-flash it. The successful part of that was on the jetson nano I have with me.
I’ll get back to you asap, thanks!
Yes, probably you would reflash a Nano, apt update/upgrade and retry these commands before installing other packages or belabox.
The good news are the raw modes provided by your cameras, so it might overcome the USB/MJPG bw issue, but the resolution x fps may be limited.
Let us know when you’re ready before trying that if required.
I did a fresh flash of the SD Card with the belabox pre-made image, which is what I want to do, but things aren’t working… I really do appreciate your help, thanks again, I’ll let you know if I decide to tackle this in the future!
What step fails ? Finding NVIDIA gstreamer plugins ? Reading camera ? Or else ?
I don’t have a Nano so cannot try to reproduce.
