Works with gstreamer but does not work with other applications?

[pedrodetroit]

Thanks to your hard work and after going through the steps of dkms ipu6-drivers, ipu-camera-bins, ipu6-HAL and icamerasrc, when I input sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=NV12,width=1280,height=720 ! videoconvert ! ximagesink

it works!
However, other applications, such as cheese or firefox do not pick up the video from the camera.

v4l2-ctl --list-devices
ipu6-downstream (PCI:pci:pci0000:00):
/dev/video1
/dev/video2
/dev/video3
/dev/video4
/dev/video5
/dev/video6
/dev/video7
/dev/video8

ipu6-downstream (pci:pci0000:00):
/dev/media0

Virtual Camera (platform:v4l2loopback-000):
/dev/video0

I think I am just missing a little thing and if someone could point it out to me I'd be grateful.
