[gst-devel] Probelm loading pipeline from XML

[Sreejesh]

Hi All,

 

I have tried saving the below pipeline to xml file using "gst-launch" with
-output option

 

[example from gstrtpbin reference]

gst-launch --output=test.gst gstrtpbin name=rtpbin \
        v4l2src ! ffmpegcolorspace ! ffenc_h263 ! rtph263ppay !
rtpbin.send_rtp_sink_0 \
                  rtpbin.send_rtp_src_0 ! udpsink port=5000
\
                  rtpbin.send_rtcp_src_0 ! udpsink port=5001 sync=false
async=false    \
                  udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0
\
        audiotestsrc ! amrnbenc ! rtpamrpay ! rtpbin.send_rtp_sink_1
\
                  rtpbin.send_rtp_src_1 ! udpsink port=5002
\
                  rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false
async=false    \
                  udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1

 

But I get an error when I try to load this pipeline using "gst-xmllaunch"
command line or using "gst_xml_get_element" in my test program.

The error is basically an assert failure for "pad != NULL".

If I construct simple pipeline like "gst-launch --output=test.gst v4lsrc !
xvimagesink" and launch the pipeline using "gst-xmllaunch test.gst", it
works perfectly fine.

Looks like I have an issue when I use "pads". 

Is there anything wrong in my procedure?

Please give me some clue to proceed.

 

Thanks & Regards
