video - detect/use rear-facing camera
I have a device which has two built-in camera: font and rear (Acer Switch).
However, I'm not able to use this second input device in any application, e.g cheese.
Not sure, but looks like a second video input was detected:
$ ls /dev/video*
/dev/video1 /dev/video2
I also tried to record directly from the device using ffmpeg as explained here:
$ ffmpeg -f video4linux2 -s 320x240 -i /dev/video1 out.mp4
... recorded and created file "out.mp4" as expected
$ ffmpeg -f video4linux2 -s 320x240 -i /dev/video2 out.mp4
FAIL: /dev/video2: Inappropriate ioctl for device
Any ideas?
Using Ubuntu 18.10 GNOME 3.30.1
