           Summary: Core could be more helpful with respect to event
                    ordering
    Classification: Platform
           Product: GStreamer

            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal

A precise sequence of events need to be sent before starting data flow. There's
already code that ensures ordering, could gst instead of throwing warnings and
errors when the ordering is not respected provide vmethods in GstElement for
handling that ?

ie we can find send_caps, send_stream_start and send_segment boolean fields
variations in multiple element methods (videomixer / adder are the ones that
come to mind), would be nice to delegate that to GstElement and have vmethods
such as get_stream_id, get_segment etc ..

I have no API proposal, just starting the discussion :)
