Philipp,

Thanks for this! I'll keep an eye out for your submission and provide testing.

I have pulled your branch and boot-tested it. I see the 2 new video
devices but noticed that the JPEG decoder shows up as an element for
video4linux2 the JPEG encoder doesn't show up (gstreamer v1.14.5) -
any idea why that would be?

Thanks,

Tim
