Gstreamer cant play stream from other pc: h264->rtp->udp


I want to stream a h264 video over UDP to another pc. I am using this pipeline to produce the stream:
videotestsrc ! video/x-raw,width=400,height=400,framerate=7/1 ! videoconvert ! x264enc ! h264parse config-interval=1 ! video/x-h264,stream-format=byte-stream,alignment=nal ! rtph264pay ! udpsink host=192.168.1.100 port=2705

I can play this on the same machine (with ip address 192.168.1.100) with this pipeline:
udpsrc port=2705 ! application/x-rtp,width=400,height=400,encoding-name=H264,payload=96,framerate=7/1 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

But when I try to stream it from another pc to the same machine I get only this output and it waits forever:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
Redistribute latency...
Redistribute latency...

What can be the problem here?


Solution

  • I found the solution. A videoconvert element is needed in the playing pipeline.
    The working playing pipeline is:

    udpsrc port=2705 ! application/x-rtp,width=400,height=400,encoding-name=H264,payload=96,framerate=7/1 ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! autovideosink
