Hello!
I want to stream mpegts over the ethernet. I use a gstreamer-pipeline from a Ubuntu PC on the streaming end (actually I want to use vlc later), and on the client, DM368, I perform the following pipeline:
gst-launch udpsrc uri="udp://192.168.1.255:5005/255" caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)MP2T-ES, payload=(int)33" ! rtpmp2tdepay ! queue ! mpegtsparse ! queue ! mpegtsdemux ! queue ! mpeg4videoparse ! queue ! TIViddec2 displayBuffer=true engineName=codecServer codecName=mpeg4dec framerate=24000/1001 ! queue ! tidisplaysink2 video-standard=auto display-output=component sync=false -vvv --gst-debug=2
I get the following behavior:
After some seconds, when the buffer is filled, I get the 1st image of my video (with false colors), and after this, I get some blocks in the picture and the video becomes unreadable and stops.
Thanks for any help in advance!
Gustav
PS:Maybe the following part of the log might be helpful:
