      @Matt-Goddard We have two different implementations for gphoto2 on VOXL. voxl-libgphoto2 which is what you are using and we also have voxl-gphoto2 which is a newer version that also uses voxl-streamer. I think I will have you try voxl-gphoto2 now.

      Here is the link to the build/install instructions for the newer gphoto2 implementation.

      Here is a link to the documentation

      You will need to use this in combination with voxl-streamer and here is some documentation for getting that going.

                The USB and Serial Debug board arrived today. I unbricked the board and installed gphoto2 and VOXL-streamer. The image below is an error I received after running the voxl-gphoto2 command.

                Please advise.

                  Have you tried gphoto2 using a Linux machine to make sure this device is supported?

                    Sony RXO

                    The RX0 II is on the list, is that what you're using?

                      Yes we are attempting to use the RX0. The image below shows that gphoto2 does detect it on an ubuntu machine.

                        @Aaron-Bottke What happens when you run gphoto2 --capture-preview? Do you get an image?

                          @Aaron-Bottke Also, can you try running voxl-gphoto2 with debugging information enabled and send us the ouput? For example: voxl-gphoto2 -d -v -g

                            Results of gphoto2 --capture-preview on my host machine as follows.

                            aa6c2695-dab0-411b-870f-8eba4001e34d-image.png

                            On the VOXL running voxl-gphoto2 -d -v -g yields way to much for me to share here so I will split it up.

                            voxl-gphoto2 -d below.

                            voxl-gphoto2 -v yields a lot of messages very quickly.
                            Output as follows.

                            voxl-gphoto2 -v yields too many messages for me to upload with a screenshot.
                            I don't see a way to submit a .txt file but the most interesting part of the output that I see is this.

                              @Aaron-Bottke Okay, thanks! That's very helpful information. It looks like the camera is producing images and voxl-gphoto2 is processing them correctly. So try voxl-streamer and see if you can stream the video. That error message seems to be coming from the gphoto2 library but doesn't seem to be hurting anything.

                                Unless I am missing something in the command this is the result from running voxl-streamer and voxl-gphoto2.

                                Thanks for all the help.

                                  @Aaron-Bottke Documentation on voxl-streamer is here: https://docs.modalai.com/voxl-streamer/

                                  For gphoto2 you will want to look at the gphoto2-mpa configuration in /etc/modalai/voxl-streamer.conf. You can use this configuration record by launching with voxl-streamer -c gphoto2-mpa

                                    That got it working!!! I really appreciate the help with this!!!
                                    My telemetry quit working though so I have to play with that and get that up and running again.
                                    Thanks!

                                      @Eric-Katzfey

                                      The gphoto-2 seams to be breaking the voxl-vision-px4 system. Any command associated with the voxl-vision-px4 system causes the voxl to kick any adb connection then prevent any from connecting until a power cycle. I can't get both voxl-vision-px4 and gphoto2 installed and running on the same system.

                                      Any thoughts?
                                      Thanks,

                                          @Aaron-Bottke I did a fresh install of system image 3.2.0 without installing any additional packages (voxl-suite). After setting up WiFi to connect to the Internet I ran these steps on voxl (over adb):

                                          • opkg update
                                          • opkg install voxl-vision-px4
                                          • voxl-configure-vision-px4 (Specifying no cameras)
                                          • Verify QGC connection with telemetry
                                          • opkg install voxl-gphoto2
                                          • opkg install voxl-streamer
                                          • voxl-gphoto2
                                          • voxl-streamer -c gphoto2-mpa

                                          I then see both telemetry and video in QGC.

                                            Not installing the voxl-suite at first and using opkg to install gphoto2 and voxl-streamer worked.
                                            Before I was following the instructions and compiling my own ipk then loading them on using adb. I've got both a video stream and telemetry over the Microhard Modem!
                                            Thanks,
