    @Kris Apologies, I'm not sure if that will work on VOXL1. Do you have a hires mipi sensor on your VOXL? It would allow you to avoid a lot of trouble

    I have also noticed that when I updated my platform to 0.9 the streamer.conf has changed.
    Now our Arducam IMX335 is not even working (it had no problems streaming before).

    0.9 streamer.conf

    {
            "input-pipe":   "hires",
            "bitrate":      1000000,
            "decimator":    2,
            "port": 8900,
            "rotation":     0
    }
    

    3.8.0-0.7 streamer.conf

      @Kris You can see supported format info here: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-uvc-server/-/blob/master/src/main.c#L64

      Another thing to try out is using gstreamer instead of voxl-uvc-server + voxl-streamer with a pipeline similar to the following:

      gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,format=YUY2 ! videoconvert ! x264enc speed-preset=ultrafast tune=zerolatency ! rtph264pay name=pay0 ! udpsink host=192.168.1.97 port=8554

      The pipeline may need to be tweaked slightly but it's one I've used before for other UVC cameras that voxl-uvc-server was unhappy with

      Do you happen to know some Gstreamer commands for the Logitech C270 uvc camera?
      I am trying to get either a streaming or recording command to work on the Seeker, with no luck so far.

        @Kris I don't have that specific webcam or a VOXL1 but with a different one and a VOXL2, all I have to do is run voxl-uvc-server, see output below:

        voxl2:/$ voxl-uvc-server 
        loading config file
        Creating new config file: /etc/modalai/voxl-uvc-server.conf

            @Kris I don't have that specific webcam or a VOXL1 but with a different one and a VOXL2, all I have to do is run voxl-uvc-server, see output below:

            voxl2:/$ voxl-uvc-server

            Thank you for your examples.

            I was asking about the C270 camera because @Eric-Katzfey had mentioned that he starts his camera testings with this model in order to locate where issues are coming from on other camera models.

            I do appreciate your support.
            I will continue to try different Gstreamer commands.

              @Kris I understand, your solution will likely be similar to what I posted above

                I was able to stream the video from voxl-portal,

                voxl:~$ voxl-uvc-server -d

                but I cannot get the Gstreamer to work for QGC.

                Here is my ERROR;

                voxl:~$ gst-launch-1.0 v4l2src device=/dev/video2 ! video/x-raw,format=YUY2 ! videoconvert ! omxh264enc ! rtph264pay name=pay0 ! udpsink host=192.168.110.152 port=8554

                Aborted
                

                Maybe its a CAPS issue?

                I had to change x264 to omxh264, and had to completely remove speed-preset=ultrafast tune=zerolatency from the command because it wasnt playing well with VOXL1.

                  @Kris Well now that you have voxl-uvc-server working you should be able to use voxl-streamer on top of that to get a stream going

                      @Kris The intention with the Logitech camera was to use it with voxl-uvc-streamer as Tom pointed out. That way you have a complete working setup and then you can start changing one thing at a time to get to what you want. If you want to switch to a different camera then you can see the differences in the new camera from the Logitech camera and try to debug that way. If you want to add a record feature with GStreamer then you can fork our voxl-streamer code and add the functionality into that. If you want to do it with a gst-launch-1.0 command line pipeline then you are farther away from anything we currently support and it's going to be hard for us to offer much help. I do think that what you are trying to do should be possible.
