    @Kris Yeah that's just the default that voxl-uvc-server uses if not explicitly specified otherwise with the -r flag.

    You can use show-video-device-info.sh and that may provide some clues.

    What is the part number or make and model of the UVC camera you're using? It's possible it's supported image formats don't match up with those supported by voxl-uvc-server

    This is all the information I get from show-video-device-info.sh

    voxl:~$ show-video-device-info.sh
    /dev/video2: e-CAM83_USB 2560:c184
    /dev/video3: e-CAM83_USB 2560:c184

      Is there any chance I can get 1920 x 1080 @30 fps using h264 in the voxl-uvc-server?
      Or is 640 x 480 the only option in the voxl-uvc-server?

            I gave this a try, but no luck.

            voxl:~$ voxl-uvc-server -d -r 1920x1080 -f 30
            Enabling debug messages
            voxl-uvc-server starting
            Image resolution 1920x1080, 30 fps chosen
            UVC initialized
            Device found
            uvc_open failed
            UVC exited
            voxl-uvc-server ending

              @Kris Are you sure that your UVC camera is 640x480 resolution?

                    I have a feeling that maybe the problem is deriving from my camera’s GUID Format.
                    Does the voxl-uvc-server accept GUID: 4832363400001000800000aa00389b71
                    for h264 format?
                    How would I go about correcting the guidFormat to match up with the voxl-uvc-server?

                      @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

                        Thank you, I will give this a try.
                        I am trying to use H.264 on this camera.
                        This is the second UVC camera that I’ve purchased because I am trying to log the frames from voxl-logger. From what I understand, H.264 output is the format that can do this.
                        Is there a way to call for only the /dev/video2 to start with the voxl-uvc-server or gstreamer?
                        Does the voxl-uvc-server accept h264 1920x1080 @30fps?

                          Do I paste this in the voxl terminal?

                          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
                          

                          Does this have uvc frame or video capture capabilities?

                            Sorry to bother you again, but I am not seeing the h264 format supported in the main.c script you provided for the voxl-uvc-server. Is it possible to edit the voxl-uvc-server main.c script to accept h264 format at 1920x1080 @30fps?

                              @Kris You can read more about how gstreamer and the gst-launch-1.0 command works here: https://gstreamer.freedesktop.org/documentation/tools/gst-launch.html?gi-language=c

                              Yes, you would run that command on VOXL2. That specific command pulls frames from /dev/video22 (the UVC camera), it tells it to expect YUY2 formatted frames (you can change this to your liking) and then it converts it to an RTSP video stream. You could modify the pipeline to instead write to a file instead of streaming.

                              There is a ton of documentation on gstreamer out there that can help you out with tailoring the pipeline.

                                Ok, thank you for the explanation.
                                I will read up on gstreamer and try to figure this out.
                                You mentioned that I would run this on VOXL2.
                                I dont have a VOXL2. Does this work on VOXL for the Seeker?

                                  @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

                                          @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.
