Original commit message from CVS:
* gst/videoparse/gstvideoparse.c: (gst_video_parse_init),
(gst_video_parse_src_event), (gst_video_parse_src_query_type):
Implement a query type function for the src pad, implement seeking
and use ANY caps for the sink pad as the element doesn't care what
caps the input has and everything is handled via properties.
