    Hi dev,

    Have you ever seen this message on QGroundControl?

    VideoReceiverLog: GStreamer error: Could not open resource for reading and writing.

    when I receive rtsp stream data from voxl, I got a this message from qgroundcontrol. so, I can't watch any streaming on QGC.

    could you please help me to resolve it, if you have any experience?

    I'm using Ubuntu 18.04.

    Thanks,

      What application are you using on Voxl to produce the stream? What kind of camera are you using? Can you try v3.5.6 of QGroundControl and see if that makes any difference?

        I used embedded program on QGroundControl to receive streaming.

        I started hires camera default using voxl-streamer.

        QGC version is latest one and got from official website.

        Thanks,

          The documentation for voxl streamer is here https://docs.modalai.com/voxl-streamer/. If you use the test pattern does that work? If not, can you go back to v3.5.6 of QGroundControl and see if the test pattern works with that? Are you sure that your network connectivity is setup properly? (e.g. can you ping from each side to the other?).

            @Eric-Katzfey I cannot see any pattern or stream on QGC yet. I verified my network connection. also, my voxl is properly connected in QGC.

            where can I find QGC v3.5.6? I only available newest software on the website.

            Thanks,
