gstreamer fallbacksrc:

https://gstreamer.freedesktop.org/documentation/fallbackswitch/fallbacksrc.html

this patch keeps voctocore up when usb/uvc v4l2src devices come and go. core will start and run when the /dev/video0 device doesn't exist.

package is waiting being accepted but I did test with
https://debusine.debian.net/debian/developers/artifact/2646769/file/gstreamer1.0-fallbackswitch_0.14.3-1_amd64.deb

As long as fallbacksrc is not available in debian stable, we have to hide this behind a config option. Please let me know if you don't have the time or knowledge to do that, i'll do that myself then.
