gst: Check for video/ caps before parsing for info

Browse source 
The gst_video_info_from_caps() API isn't really intended to be used as a
check-for-videoness function (it generates an error-level GStreamer
debug message when used this way).

We check the caps for a video/ name for this reason, which is
functionally equivalent.
