[maemo-developers] Gstreamer: udp bug?

[From: ext-lukasz.1.kondrad at nokia.com]

Hi all 

I want to have a simple RTSP client on N810. I was thinking that
gstreamer would be the easiest solution. The first step iwas to received
only video. The command line to do that is: 

gst-launch rtspsrc location=rtsp://path/to/file ! decodebin !
ffmpegcolorspace ! Autovideosink

This works in SDK for X86 target, but when I tried it in the N810 I got
warning that gstudpsrc has no property name 'sock', gstudpsink has no
property name 'sockfd' and 'closefd'. The pipline goes to state PLAY and
do nothing. 

I checked using wireshark what are the exchange information between N810
and RTSP server (if any). I found out that setup part works ok, the N810
and RTSP exechenge the information and RTSP server send sdp description
to N810 and the RTP stream is send on proper address but wrong udp port
(different than in sdp file). The wrog port is requested by rtspsrc on
N810 (so server works fine) . My thinking is that warning about missing
properties is the problem. 

My question: is it a bug ? 

Regards, 
Lukasz
