    @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

    @wilkinsaf Sorry, it was setup as private. I changed it to public. Can you try again?

              @Eric-Katzfey

              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.

                            Yes, let me try one at a time now.
                            Here are the two cameras

                              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

                                      @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.

                                        @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.

                                        @Eric-Katzfey Sounds good.

                                        The other camera is giving me this error

                                        The one I compiled could not find the device at all

                                          @wilkinsaf Perhaps you are working on master branch? The latest and greatest (The one you should be using) is the dev branch.
