Hi,

My server has this bin: ( appsrc name=playsrc ! vorbisparse ! rtpvorbispay 
pt=97 name=pay0 )"
My play command is: gst-launch-1.0.exe rtspsrc
location=rtsp://127.0.0.1:8554/test/play rtpvorbisdepay  ! vorbisparse  !
autoaudiosink

Media is pushed to my appsrc pad.The caps seems alright and but on the
server I get:
0:00:06.137286500 22042 0x7ffff80014c0 FIXME                default

and the client:

ERROR: pipeline doesn't want to preroll.

I do not really get it. What do I need to set?

Regards,
Eric
