Not able to get audio caps for mp4

[Frank Schimer]

Hi Marc,

I am working on streaming a mp4 stream over the network,
I am using the following pipeline to stream video  on the server end:-

$: gst-launch-0.10 -v filesrc location=input.mp4 ! qtdemux name=demux
demux.video_00 ! queue ! h264parse ! rtph264pay config-interval=1 !
udpsink port=8080 host=ip

On client side:-
$ gst-launch-0.10 -v udpsrc uri=udp://ip:5002 caps="<CAPS>" ! queue !
rtph264depay ! h264parse ! ffdec_h264 ! xvimagesink

I can successfully stream the video but I am not able get the audio.

Any pointers would be very much helpful.

Thanks,
--Frank
