[gst-devel] Gst : MPEG-4 streaming not working

[Bhavana Bhat]

Hi

I'm trying to stream a .mp4 file using the following Gstreamer command
and a helix server.

gst-launch-0.10 rtspsrc location=<rtsp .mp4> !
rtpmp4vdepay !
ffdec_mpeg4 ! xvimagesink

It does not seem to be working. The following is the error message thrown:

You need to explicitly set elements to the NULL state before
dropping the final reference, to allow them to clean up.

============================================================


Initial RTSP
message exchange seems to be successful. Even SDP file
is
retrieved[test.pcap attached]. Further RTP doesnt seem to get
triggered.

The same file seems to be playing with real player.

Can someone let me know what is the problem here?

I want to get a streamer server-client set-up quickly.
Is there any way where I can get a complete setup with
both server and client in Gstreamer?

Thanks
