hello adrien.leroy2,
please check the sensor capability via v4l2 utility, i.e. $ v4l2-ctl -d /dev/video0 --list-formats-ext
it’ll report available sensor formats if you’d implementation correctly.
after that,
please enable the gstreamer pipeline with v4l2src for verification,
for example,
$ gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw, format=GRAY8, width=640, height=480, framerate=30/1' ! fakesink
or
$ gst-launch-1.0 v4l2src device=/dev/video0 ! 'video/x-raw, format=GRAY8, width=320,height=240' ! glimagesink
BTW,
you may also refer to Topic 51136 , and Topic 175089 as see-also.
thanks
