[gst-devel] Streaming with GStreamer

Thu Sep 7 13:26:33 CEST 2006

Hi,

Ok, it is just an error in the libgstamrnb plug-in
 so I change some
configuration to this and resolve the error 

Now it done something I can’t understand as there’s no error just in the
pipeline but where????

[root at lfm developpement_pc]# gst-launch-0.10 --gst-debug=3

Do you have the implementation of function: Decoder_Interface_Decode?

Best Regards,

Yan

Hi Deeptendu,

Thanks for all your help .. I try what you say :

gst-launch-0.10 --gst-debug=3 --gst-debug-no-color rtspsrc
location="rtsp://172.16.10.26:554/sample_h264_1mbit.mp4" ! rtpmp4vdepay !

ffdec_mpeg4 ! ximagesink

But it doesn't work, it says :

I don't know where is the error as I don't understand this error. And so I'm
not an GStreamer Expert ...

Thanks,

Jérémie

Hi Jeremie,

Try out this first:

gst-launch --gst-debug=3 --gst-debug-no-color rtspsrc location=<RTSP URL> !
rtpmp4vdepay ! ffdec_mpeg4 ! ximagesink

Make sure that the URL streams out a MP4V-ES only. See what RTSP/RTP packets
are being exchanged by doing an Ethereal packet capture.

For more detailed debug messages, increase the gst-debug level to 5 and
redirect 2 (stderr) to a file for detailed examination. However I don't
think that will be required, since from the error messages you sent earlier,
it looks to be a network or server problem and not got anything to do with
gstreamer. Anyway, the packet capture will reveal if that is so. 

For me the above has worked.

Regards,

Deeptendu

Hi,

I try to make streaming with GStreamer but there are always connection
errors with the server (Helix Universal Server or Darwin Streaming Server)
.

Which server did you use for the streaming?

Is the plug-in RTSP ok????

Can you help me?
