    @Eric-Katzfey

    Apologies for the delay. Some other things came up.
    I was able to pull down the camera information. We have 2 cameras we are trying to get up.

    Cam 1: https://pastebin.com/qHvHKXay
    Cam 2: https://pastebin.com/7DgvP58k

    They appear to be able to post in MJPEG

    @wilkinsaf There is a new version of libuvc available at http://voxl-packages.modalai.com/dev/libuvc_1.0.2_202112182223.ipk with the changes. If you rebuild the dev branch of voxl-uvc-server and install build deps from dev you should pick up the new libuvc. Then you can rebuild and test with your camera.

          @Eric-Katzfey Sorry for being such a pain, but it seems like this repo keeps moving.

          I went to https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-uvc-server

          but got this

          I keep searching around for the repo, but can not find it

                      We seem to be having trouble finding the camera now which is weird. I wonder if we need to specifically download and install the drivers?

                        @wilkinsaf No, you shouldn't need any drivers. Any USB device should be listed with lsusb, even without any specific drivers. Does it show up when plugged into a regular Linux computer?

                          @Eric-Katzfey Yes, we have hardwired it into a computer before. We have seen the stream using ffmpeg on VOXL as well. We just can not seem to get voxl-streamer to work with it

                            @wilkinsaf If you unplug the camera from Voxl does anything disappear from the lsusb list?

                              Yes, the top 3 entries in lsusb screenshots above are all cameras. I can unplug those one by one and see them disappear.
                              Would it matter if we have 2 UVC cameras?

                                @wilkinsaf Just try one at a time for now. And when you plug the camera in do you see a new /dev/videoX entry appear?

                                  @wilkinsaf Also, were you able to get the ordering information for these cameras? If they aren't too expensive I would like to order at least one of them to test against.

                                      @Eric-Katzfey

                                      Good news, I was able to get voxl-uvc-server to spin up with one usb camera connected.
                                      21d09d1b-d888-45a2-a663-51af22ab926b-image.png

                                      However, I am getting this issue from voxl-streamer
                                      cc766c80-29ad-4160-8191-964e40998ea5-image.png

                                      Seems like I need to figure out the frame size and set the correct one. Let me play around with that now

                                        @Eric-Katzfey Doesn't look to be frame size as the "sizes" seem non-deterministic

                                          Good news, I was able to get voxl-uvc-server to spin up with one usb camera connected.
                                          21d09d1b-d888-45a2-a663-51af22ab926b-image.png

                                          However, I am getting this issue from voxl-streamer

                                          Seems like I need to figure out the frame size and set the correct one. Let me play around with that now

                                          @wilkinsaf Great, that's some progress! What about if you try the other camera? Not sure why the frame length is different. For a given resolution and frame format that number should be a constant. (e.g. 640 x 480 x 2).
