Hi there,
I am trying to get video from my Panasonic NV-GS11 to ffmpeg. I am
certain that the device is supported, as the UVC web site explicitly
lists it, and the device ID matches that in the UVC web site's
compatible devices list.
I have output the error that ffmpeg outputs, which I think is being
caused in the UVC layer. I have included the output of lsmod, lsusb and
lsusb -v for that device, just to confirm that, as far as I can tell,
the device is connected properly.
I would be extremely grateful if anyone can tell me what is causing
the problem.
Thanks in advance!
