Sending RTP to linphone.

[mohammad shoujaa]

Hi,

I have an issue in sending RTP to linphone. 

 

When I play the following pipeline :

 

gst-launch-1.0 -v filesrc location=C:/ test.mp4 ! qtdemux ! avdec_h264 !
x264enc bitrate=192 ! rtph264pay ! udpsink host=127.0.0.1 port=9078

 

everything is ok and the video played in linphone screen.

But what I want to do is to save first the video streams into a file then
send this file to the linphone. What I did is the following:

 

Saving into a file:

gst-launch-1.0 -v filesrc location=C:/ test.mp4 ! qtdemux ! avdec_h264 !
x264enc bitrate=192 ! filesink location=C: /videosample

 

Send to linphone:

gst-launch-1.0 -v filesrc location=C: /videosample ! h264parse ! rtph264pay
! udpsink host=127.0.0.1 port=9078

 

the packets received but the linphone played a black screen.

I want to know what I am missing in my pipelines or if there is a specific
parameter to set.

Note that it is working when a play a gst receiver :

gst-launch-1.0 -v udpsrc port=9078 caps = "application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264,
payload=(int)96" ! rtph264depay ! avdec_h264 ! autovideosink

 

 

 

Kind Regards,
