Thank you for your answer

ahcsrc uses the Camera API (old, deprecated version), which does not
support an external camera attached via USB.
Technically I can set proper permissions on the device node since it is a
rooted android device, but the better way seems to be to get the buffers
off the v4l2 device and push them in through appsrc.

I just thought if there is a quick and dirty way, I'll prefer that.
