    @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).

    @Eric-Katzfey

    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.

        @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.

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

            @wilkinsaf Thanks! I'm going to order them so that I can have them as part of our normal USB UVC camera test suite.

              @Eric-Katzfey Thanks Eric!

              I switched to dev branch (slightly embarrassing as you told me to switch to dev) and pull

              voxl:~/voxl-uvc-server(dev)$ git pull origin dev
              From https://gitlab.com/voxl-public/modal-pipe-architecture/voxl-uvc-server
               * branch            dev        -> FETCH_HEAD
              Already up-to-date.
              

              I made sure to install the correct libuvc ipk

              voxl:~$ opkg install libuvc_1.0.2_202112182223.ipk
              Collected errors:
              * opkg_prepare_file_for_install: Refusing to load file 'libuvc_1.0.2_202112182223.ipk' as it matches the installed version of libuvc (1.0.2).
              

              I then built the voxl-uvc-server, ran Makefile, and tried to run

                @wilkinsaf Okay, interesting. Let's go back to the original camera with the incorrect size. Can you add the patch I suggested and see if you can make that camera work?

                        @wilkinsaf Unfortunately, it's hard to debug this without actually having the camera in my test setup. I've never seen a camera stop being detected like that. I did order the cameras but won't have them in my possession until the 9th of January.

                          @Eric-Katzfey My apologies. I thought I sent a response to this.

                          Totally get it. Debugging over a message board is really hard. I believe my associate is getting some of the cameras to your offices sooner than the 9th.

                          I have been continuing to try different things on our end.

                            @wilkinsaf I have both of the cameras now. I have updated libuvc to version 1.0.3 (http://voxl-packages.modalai.com/dev/) and voxl-uvc-server to version 0.0.6 (http://voxl-packages.modalai.com/dev/). The voxl-uvc-server update isn't really necessary but I cleaned up a little bit of the debug logic. There was a check that was failing in libuvc for the Blue Robotics camera (USB 32e4:9422, "H264 USB Camera") so I removed that check and then it started working. So far it has been reliable. The other camera (USB 337b:090c, "HBVCAM 5M-AF") was coming up without these changes. However, it isn't reliable. Sometimes uvc_open will fail, other times it will pass. If it passes then sometimes it will successfully start streaming and other times it will think it was successful but gets no frames. Not sure why it is having these issues so need to debug more.

                                @wilkinsaf A new version of voxl-uvc-server was just posted here: http://voxl-packages.modalai.com/dev/. Documentation has been updated accordingly: https://docs.modalai.com/voxl-uvc-server/. Seems to be working pretty well with your cameras but one of them will fail occasionally. The program will fail and you can try again when that happens. Still not sure why it isn't reliable on all cameras.

                                    @Eric-Katzfey the uvc-server appears to be working. however, the voxl-streamer does not seem to be able to connect to the pipe. is there a different voxl-streamer command than what was mentioned above?

                                    voxl-streamer -f /usr/share/modalai/voxl-streamer/voxl-streamer.conf -c uvc-server

                                      @wilkinsaf A new version of voxl-uvc-server was just posted here: http://voxl-packages.modalai.com/dev/. Documentation has been updated accordingly: https://docs.modalai.com/voxl-uvc-server/. Seems to be working pretty well with your cameras but one of them will fail occasionally. The program will fail and you can try again when that happens. Still not sure why it isn't reliable on all cameras.

                                        @wilkinsaf Yes, there is a newer version of voxl-streamer available that has some new configurations defined. See documenation here: https://docs.modalai.com/voxl-streamer/#streaming-uvc-cameras-from-voxl-uvc-server

                                          @Eric-Katzfey I am not seeing the uvc-generic in my /etc/modalai/voxl-streamer.conf file after my install of voxl-streamer_0.2.7_202111272338.ipk

                                          Is there a repo online of these .conf files?

                                          I found the voxl-streamer.conf file in the gitlab repo, however I do not see the uvc-generic tag in any of the branches I looked through
