This should also help the sink if I'm not missing anything, at least if the
sink is providing buffers to upstream.

    v4l2: try to allocate new buffers with VIDIOC_CREATE_BUFS if needed

    If max_buffers is 0 then an arbitrary number of buffers (currently 4) is
    allocated. If this is not enough v4l2src starts copying buffers.
    With this patch VIDIOC_CREATE_BUFS is used to allocate a new buffer. If
    this fails v4l2src falls back to copying buffers.
