Hi,

On Ubuntu 14.04 using Gstreamer 1.4.x, I'm having a problem getting a v4l2src
to work reliably. It appears that the driver is working ok (according to the
attached logs) but almost immediately there's an indication that the bufferpool
has reached the end of the stream.

Here's the command line I used to generate the attached log:

GST_DEBUG="v4l2*:7" gst-launch-1.0 v4l2src ! video/x-raw, format=YUY2,
width=1920,height=1080,framerate=2997/100 ! checksumsink 2> gst.log


Rebooting the machines (I've tested this on several) will solve the issue...for
one invocation. Then, if I run the command line a second time, the above issue
occurs again and again.

My capture device is a USB3 capture dongle manufactured by Magewell

Thank you!
