JetRacer Jetcam error

The error message is “Could not initialize from camera”

Success in Test camera with command, but we failed at that…

Please help!!

You need to test the CSI camera works well.

-  /dev/video0 is existing 
- $ gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! nvoverlaysink
- $ gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! \
   'video/x-raw(memory:NVMM),width=3280, height=2464, framerate=21/1, format=NV12' ! \
   nvvidconv flip-method=0 ! 'video/x-raw,width=960, height=720' ! \
   nvvidconv ! nvegltransform ! nveglglessink -e

The Camera works well, then run the jetcam example.
If CSI camera cannot be initialized as expected, try this command. It works well at JetRacer.
$ sudo systemctl restart nvargus-daemon

We have error in first row…( $ gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! nvoverlaysink)

I think the pipeline matters…

Plz…Help…

and Thanks for your reply

@jenny_jung
When you enter the command which has a backslash(’’), you should be careful.
The command is an one-line content, not separated lines.
That is, enter this at a time:

gst-launch-1.0 nvarguscamerasrc sensor_id=0 ! 'video/x-raw(memory:NVMM),width=3280, height=2464, framerate=21/1, format=NV12' ! nvvidconv flip-method=0 ! 'video/x-raw,width=960, height=720' ! nvvidconv ! nvegltransform ! nveglglessink -e

BTW, how about ‘/dev/video0’ ?

only video0.

I solved this problem. Thanks for your help.

But I have another problem about “train” process. Could you help me?

Would you explain much more what’s wrong?
