    @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

                  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.

                                  Good news, I was able to get voxl-uvc-server to spin up with one usb camera connected.

                                  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

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

                                      @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).

                                        Good suggestion. Let me try that.
                                        Check out the length when uvc server fires up

                                        Got frame callback! frame_format = 3, width = 640, height = 480, length = 613376, ptr = 0
                                        

                                        interesting

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

                                          @wilkinsaf You can try modifying this line in voxl-uvc-server: https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-uvc-server/-/blob/dev/src/main.c#L83

                                          Make it read: .size_bytes = 614400, \

                                          Then rebuild it and try again.
