    @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

    No, I dont have a hires mipi sensor on my VOXL. I am using the TOF, Stereo, and Tracking sensors specifically for indoor flights.
    I am just trying to record frames or video from a connected uvc camera while in flight.
    I am also trying to set one of my stereo cameras as the QVIO instead of the tracking camera. Again this is just for indoor flights. I have also asked about this QVIO setup in this thread, but have not received a response other than pointing to the extrinsics ModalAi page.

      The command you sent me earlier this week did not work on the VOXL platform. I tried variations on both our e-CAM83 and Aruducam IMX335 uvc camera modules.

      Could you please point me to a uvc camera that will work with the voxl-uvc-server?
      Our main goal is to connect a uvc camera to the Seeker and be able to capture frames or video (streaming is not necessary) and send them to an onboard SD card (possibly using voxl-logger.

      Would this Blue Robotics uvc module work? Meaning, is it capable of connecting to the voxl-uvc-server and be able to send frames and/or video to the onboard SD card using voxl-logger on the VOXL1 Seeker Dev Drone?

        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
        }

          @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
            =================================================================
            width:                            640
            height:                           480
            fps:                              30
            pipe_name:                        uvc
            =================================================================
            

            I'm able to pull up the stream using voxl-portal (going to IP of my VOXL2 in browser)

            8ff0d084-6556-4947-8dcb-9e8137d10ae1-image.png

            Then alternatively I'm able to use this gstreamer command:

            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=192.168.1.124 port=8554
            

            to pull up the video stream in QGC

                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.

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

                    but I cannot get the Gstreamer to work for QGC.

                    Here is my ERROR;

                    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.
