Comment (by danielk):
Yeah this tells me the driver just isn't sending data but we still have a
valid file descriptor.
Mauro explained to me some of the limitations of the streaming
implementation for several of the V4L cards. It basically comes down to
needing to close the data reading file descriptor while issuing the
streamoff/streamon to the device and then reopening it to get the data.
I've implemented a proof of concept patch for this in #10519. That patch
didn't work for the reporter on that ticket but may work for you.
(nocarrier1969 in IRC did some testing last night that looked positive.)
It's a PoC patch which may have some unrelated problems so try it a few
times if the first attempt fails.
