Hi, I've not used gstreamer before and I am thus struggling with displaying a video stream from a 'Makito X Encoder'. The endpoint is on my local network and has the form: udp://@239.256.0.1:2000 The video is H264. The transport stream is set to MPEG2 transport stream over UDP (no RTP header). I can display the video stream reliably using VLC and QtAV. I have tried the following command: gst-launch-1.0 uridecodebin uri=udp://@239.255.0.1:2000 ! tsdemux ! h264parse ! video/x-h264 ! avdec_h264 ! autovideosink sync=false However the command exits and I get the following output on the console (GST_DEBUG=2). Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Got context from element 'autovideosink0-actual-sink-vaapi': gst.vaapi.Display=context, gst.vaapi.Display=(GstVaapiDisplay)"\(GstVaapiDisplayGLX\)\ vaapidisplayglx1"; Setting pipeline to PLAYING ...

Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... I can display a local video file so I am fairly sure I've built gstreamer correctly. How can I display the video stream reliably? I'm using gstreamer version 1.14.2.

The error below is obscure, but my impression is that you need a videoscaler to adapt the non-square pixel aspect ratio for your display. You could try with a scaling display like xvimagesink or glimagesink too, it's a bit of a guess. I believe we have used the makito that way before, even though we usually use SRT. From the output, it would seem that the mpeg take part is working.
