I’ve spent quite some time now trying to run my PI camera V2.1 on a rock4SE running raspbian without success. My goal here, is really just to test that the camera is working.
I first hadn’t got any /dev/video0 device, so I followed the instructions on the following post: https://www.linuxquestions.org/questions/linux-newbie-8/missing-dev-video0-261133/
“rm /dev/video /dev/video0
mknod /dev/video0 c 81 0
chmod 666 /dev/video0
chgrp video /dev/video0
ln -s /dev/video0 /dev/video”
And I do have a shinny new /dev/video0 although I am not sure it is in any way linked to the actual MSI camera I plugged onto board…
So then I’ve tried launching the following command:
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=1920,height=1080, framerate=30/1 ! xvimagesink
which insults me back:
Setting pipeline to PAUSED …
ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not open device ‘/dev/video0’ for reading and writing.
Additional debug info:
…/sys/v4l2/v4l2_calls.c(622): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
system error: No such device or address
ERROR: pipeline doesn’t want to preroll.
Failed to set pipeline to PAUSED.
Setting pipeline to NULL …
I’m really not sure why such error happens. I have tried giving to chmod 777 /dev/video0 for testing but it didn’t change anything.
This is rather puzzling to me since this very camera worked just fine on a RPI2.
If you guys have any tip on how to get this simple command working, any workaround anything… that would be apperciated.
