[gst-devel] Streaming with GStreamer

[Jérémy Garnier]

Hi,

 

It is normal that there’s no trame on port 554 when i launch the streaming??
On the streaming server, I see a connection but nothing on the client screen



I try to execute without debug trace, I have :

 

[root at lfm developpement_pc]# gst-launch-0.10 rtspsrc
locationfiltered="rtsp://172.16.10.26:554/sample_h264_1mbit.mp4" !
rtpmp4vdepay ! ffdec_mpeg4 ! ximagesink
Setting pipeline to PAUSED ...

ERROR: Pipeline doesn't want to pause.
ERROR: from element /pipeline0/rtspsrc0: Could not setup rtp.
Additional debug info:

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

Please use

 

gst-launch-0.10 rtspsrc
location=rtsp://172.16.10.26:554/sample_h264_1mbit.mp4 ! rtpmp4vdepay !
ffdec_mpeg4 ! ximagesink
 

and see what happens.

 

Streaming should start. However, if the elementary stream is H.264, then you
would be able to see the video, since there is no depayloader plugin
available as yet in GStreamer. Stream out a MPEG-4 video (in that case use
rtpmp4vdepay and ffdec_mpeg4) or H.263 video (use rtph263pdepay and
ffdec_h263).

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????
