    I am using custom gstreamer pipeline in Qt5.15 to show a video stream

    udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)RAW, sampling=(string)YCbCr-4:2:2, depth=(string)8, width=(string)720, height=(string)576, colorimetry=(string)BT709-2" port=5 ! rtpvrawdepay ! queue ! videoconvert ! autovideosink

    However, as far as I know qt6 does not accepts custom pipelines.
    I want to try Qt6, what I need to define as url to MediaPlayer?
    Source ip address is 169.254.188.4

      Hi and welcome to devnet,

      From the top of my head, try using:

      rtsp://169.254.188.4
      

      Hope it helps

        I tried your suggestion and many other variations to correctly define the url path, yet never able to get any visuals.
        I guess I am stuck with the Qt5 for now.

          Try using a .sdp file, this allow to specify video stream configuration.
          At the top of my head, this may enough :

          v=0
          s=My session name
          i=Short video infos
          m=video 5 RTP/AVP 96
          c=IN IP4 0.0.0.0
          a=rtpmap:96 H264/90000
          a=recvonly
          

          Note than port number is specified under m (media) field

          More informations can be found at https://en.wikipedia.org/wiki/Session_Description_Protocol

          I know than .sdp file are supported in Qt 5.x.y series, I have not try yet wih Qt 6 series (I'm stuck with Qt 5 series for another reasons)
