    @modaltb Thanks for the response! So we can get it to trigger, and we have got it to work with Sonys webcam software separately!. It says it is streaming, but we can not receive video like it's sending empty data. Libg Photo 2 is reading the camera and recognizes it, but can't pull the video up in QGC or any other video source. It's just one of those things we have been spending a ton of time on scratching our heads, knowing there is something small we are missing haha! First time using VOXL and Modem..which I must say is absolutely amazing, we want to switch our fleet over to this system.

    Hi @Matt-Goddard, I understand that you are using QGC, are you able to get telemetry through to QGC? If so, are you doing that over WiFi or Microhard?

    It looks like you are successfully getting frames off of the camera, so I'm wondering if there is a networking issue.

      Yes, Tom we are getting full telem using the Microhard through QGC, also have used WiFi. Yes, that was odd to me as well?

        @Matt-Goddard Okay, so I assume you are using voxl-vision-px4 to talk with QGC then. You will want to point voxl-libgphoto2 to the IP address of your ground station on the Microhard network, which would be the same IP address that you are sending voxl-vision-px4 to.

        Right now it seems as though your voxl-libgphoto2 is attempting to send video to QGC over WiFi, when in reality you are connected to QGC over Microhard.

        So, instead of using voxl-libgphoto2 192.168.1.215, you will want to use the same IP address as you are for voxl-vision-px4, which you can find using ifconfig on your ground station or should be in voxl-vision-px4's config file: /etc/modalai/voxl-vision-px4.conf. All Microhard IPs will be in the form 192.168.168.X

            Are you able to open the video stream with a different program like VLC or ffplay?

              We have tried VLC with both Linux and Windows, appears to load it with no video stream.

                @tom is the VOXL streamer apk required in order to use the gphoto2 to stream video?

                  @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.

                              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

                                        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 -v yields a lot of messages very quickly.

                                        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.
