After gstreamer rework the dynamic resolution change handling, gstreamer
stop doing capture buffer allocation based on guesses and wait for the
source change event when available. It requires driver always notify
source change event in the initialization, even if the size parsed is
equal to the size set on capture queue. otherwise, the pipeline will be
stalled.

Currently driver may not notify source change event if the parsed format
and size are equal to those previously established, but it may stall the
gstreamer pipeline.
