Getting gst_element_query_position to return NTP time

[Serj TorresSoldado]

Hi All,

 I want gst_element_query_position to basically return a value in sync with
the NTP timestamps in the RTCP SR packets from the sender. Is this
currently possible? It seems such a useful functionality so I think I am
missing something..

 Using rtspsrc/rtpbin and playing around with the properties as suggested
in the following presentation (see below for the URL) seams to have no
effect.

Rtpbin receives the RTCP timestamp in gst_rtp_bin_handle_sync(), curiosely
I haven't seen
 gst_rtp_bin_associate() being called from this function although I see the
SDES packets passing.

 If such a feature doesn't exist what would be the best way to implement it?

 Any help would be great. Thanks.
