Created an attachment (id=139780)
 --> (http://bugzilla.gnome.org/attachment.cgi?id=139780&action=view)
change where buffers are dequeued for v4l2sink

The attached patch can be applied on top of the previous patch;  it changes
v4l2sink to dequeue a buffer if the driver already has more than one buffer. 
This way, the DQBUF happens when the frame is rendered, not later when
_buffer_alloc() is called (which, at least with our current v4l2 display
driver, was causing periodic ~180ms latency when dequeuing buffers, which was
causing problems with A/V sync)
