Hey!!! That is crazy! Who created such retard API?? In both cases you
are going to show video from /dev/video6 device. But in real I have two
independent camera devices: front and back.

Why on the earth I cannot have /dev/video0 for back camera and
/dev/video1 for front camera? And need to call such huge commands which
re-route pictures from correct camera to /dev/video6 device? I'm really
not interested in some hw details how are cameras connected, I just want
to show pictures in userspace...

And what are those others /dev/video[0-5] devices?
