Support more pixel formats in v4l2 camera backend
...
These were tested with gstreamer and v4l2loopback, example setup:
$ sudo v4l2loopback-ctl add -n BGRA 10
$ gst-launch-1.0 videotestsrc pattern=smpte-rp-219 ! \
video/x-raw,format=BGRA ! v4l2sink device=/dev/video10 > /dev/null &
Then conversion was confirmed with video_loopback:
$ ./video_loopback --capture_device_index=3 --logs 2>&1 | grep -i \
capture
