I Got this in the beginning of pipeline <div style="margin-left: 40px;">Setting pipeline to PAUSED ... /playbin0/source/rtpbin0: latency = 3000 /playbin0/source/udpsrc0: timeout = 5000000 /playbin0/source/udpsrc2: timeout = 5000000 Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... /playbin0/source/udpsrc0: timeout = 0 /playbin0/source/udpsrc2: timeout = 0 </div>     <from here a lot of caps info output> and then after freeing pipeline <div style="margin-left: 40px;">/playbin0/vbin/videosink/videosink-actual-sink.sink: caps = NULL /playbin0/vbin/videosink.sink: caps = NULL /playbin0/vbin/vscale.src: caps = NULL /playbin0/vbin/vscale.sink: caps = NULL /playbin0/vbin/vconv.src: caps = NULL /playbin0/vbin/vconv.sink: caps = NULL /playbin0/vbin/id.src: caps = NULL /playbin0/vbin/id.sink: caps = NULL /playbin0/vbin.sink: caps = NULL </div> So i think, at the end of output , didnt describe the complete pipeline.Any idea?
