My webcam (hardware/kernel?) has a nasty bug where the streaming seems to fail
to start. Causing the v4l2src element to block on a VIDEOC_DQBUFF ioctl
forever.
While this is obviously a bug on a lower level, it does reveal the issue that
gst open the v4l2 device in blocking mode. cameras can potentially capture at
very low rates (capture time of second or more), it's quite annoying that in
the worst case setting the element to state NULL would then cost of the order
of seconds..
