So this happens when the driver (correctly) advertises support
for streaming modes via the v4l2 api, and mythtv (incorrectly)
tries to stop streaming, when it's not even setup to do so.

It'll require a patch (hack) to the mythtv sources to get
around this.

See
https://code.mythtv.org/trac/ticket/12522
https://code.mythtv.org/trac/ticket/12336 <- latest patch

we need to identify the correct driver name string for your
hardware, and it should all spring to life....

What does the following report for your system???

# v4l2-ctl --all -d /dev/video0
# v4l2-ctl --all -d /dev/video1
