Original commit message from CVS: Patch by: Sjoerd Simons <sjoerd at luon dot net> * gst/mpeg4videoparse/mpeg4videoparse.c: (gst_mpeg4vparse_set_new_caps), (gst_mpeg4vparse_align), (get_bits), (next_start_code), (gst_mpeg4vparse_handle_vos), (gst_mpeg4vparse_push), (gst_mpeg4vparse_drain), (gst_mpeg4vparse_chain), (gst_mpeg4vparse_sink_setcaps), (gst_mpeg4vparse_sink_event), (gst_mpeg4vparse_src_query), (gst_mpeg4vparse_set_property), (gst_mpeg4vparse_get_property), (gst_mpeg4vparse_class_init), (gst_mpeg4vparse_init): * gst/mpeg4videoparse/mpeg4videoparse.h: Parse the config data (either outbound or in the stream) to set width/height, apect ration, framerate in the caps if applicable. Mark frames as GST_BUFFER_FLAG_DELTA_UNIT when they are not intra frames Set the timestamps of outgoing buffers to the buffer in which the VOP header was found. Drop incoming data untill configuration is found (by default, configurable using a property). Report a 1 frame latency. Fixes #532723.
