I'm trying to play streaming video from dvblast (dvb-s) to my pandaboard and have issues. Can someone give me any directions?

this is my output: 

gst-launch-0.10 -vm udpsrc port=1234 multicast-group=239.255.0.1 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,payload=(int)96" ! .recv_rtp_sink_0 gstrtpbin latency=800 ! rtpmp2tdepay ! tsdemux ! ffdec_h264 ! xvimagesink 

Setting pipeline to PAUSED ... ERROR: Pipeline doesn't want to pause. 
Got message #9 from element "xvimagesink0" (error): GstMessageError, gerror=(GError)NULL, debug=(string)"xvimagesink.c(1428):\ gst_xvimagesink_get_xv_support\ ():\ /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0:\012No\ port\ available"; ERROR: from element /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: Could not initialise Xv output Additional debug info: xvimagesink.c(1428): gst_xvimagesink_get_xv_support (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: No port available Setting pipeline to NULL ...

seems like your X-server on the pandaboard isn't setup properly. on the panda, can you run a simple pipeline like the following?

gst-launch videotestsrc ! xvimagesink

you might want to try the "autovideosink" instead of the "xvimagesink", which can choose the "best" video output among those installed.

  • Hi Umlaeute, thank you for the reply. the above command works. I can see the test screen, what am i doing wrong? – frederic Apr 28 '12 at 12:19
  • your initial problem report indicates that you had problems with xvimagesink; you might try to use "autoimagesink" – umläute Apr 29 '12 at 15:28
  • Ok perfect, autovideosink gives no error, but i get a blank screen. Does anybody know the correct pipeline for dvb-s stream from dvblast? – frederic Apr 29 '12 at 19:40
