Hi. I started trying to track this down in libcamera, but was directed here.
The bug report there is https://bugs.libcamera.org/show_bug.cgi?id=270 and they
suggested I report to linux-media and linux-usb lists. I'm reporting here
first, since I'm running a stock Ubuntu kernel.
My webcam does not work for video capture, though audio does work.
jlquinn@cerberus:~/Videos/junk1$ v4l2-ctl --device /dev/video0 --stream-mmap
--stream-to=frame.raw --stream-count=1
VIDIOC_STREAMON returned -1 (Protocol error)
According to the reply from the libcamera folks, this should save a
frame to file.
When I plug the camera in, I get the following in my log:
