    @tom Thank you.

    I tried it again without manually running voxl-streamer.
    First I made sure it was on by inspecting my services.
    When I confirmed that it was on, I tried to input the rtsp:// in the Open Network Stream in VLC, but it failed.
    Here is the error message in VLC

    Connection failed:
    VLC could not connect to "192.168.110.152:8900".
    Your input can't be opened:
    VLC is unable to open the MRL 'rtsp://192.168.110.152:8900/live'. Check the log for details.
    Connection failed:
    VLC could not connect to "127.0.0.1:8900".
    Your input can't be opened:
    VLC is unable to open the MRL 'rtsp://127.0.0.1:8900/live'. Check the log for details.
    Connection failed:
    VLC could not connect to "192.168.110.159:8900".
    Your input can't be opened:
    VLC is unable to open the MRL 'rtsp://192.168.110.159:8900/live'. Check the log for details.
    
    

    Can you confirm that I should be using the rtsp://192.168.110.152:8900/live for the VLC network stream?
    Or should it be rtsp://127.0.0.1:8900/live ?

    voxl:~$ voxl-streamer -i tracking
    Waiting for pipe tracking to appear
    Found Pipe
    detected following stats from pipe:
    w: 640 h: 480 fps: 30 format: RAW8
    Stream available at rtsp://127.0.0.1:8900/live
    
    

    Here is my settings in voxl-mavcam-manager

    {
            "snapshot_pipe_name":   "tracking",      
            "video_record_pipe_name":       "tracking",           
            "default_uri":  "rtsp://192.168.110.152:8900/live",
            "enable_auto_ip":       true
    }

        @Kris Again, you've ran through voxl-configure-sku and voxl-configure-mpa there is no reason to start a service manually. In your first post you could see that voxl-mavcam-manager was already running as a service.

        What do your video stream settings look like in QGC? Do you have it setup correctly to expect an rtsp stream?

          Yes, I have ran through the voxl-configure-sku and the voxl-configure-mpa.
          This is what my video stream seetings look like in QGC, if its the correct location.

            The video stream settings are under "General", you'll want to enter the RTSP URI there

                                @Kris , please try the following:

                                • verify the ip address of voxl2
                                  • when you adb into voxl2, the ip address is printed
                                  • you can use ifconfig to check the ip address
                                • make sure voxl-streamer is running (it looks like it is based on output of systemctl status voxl-streamer
                                • ping your voxl2 ip from your host machine (just to make sure it can reach voxl2)
                                • download ffmpeg / ffplay to your host machine
                                  • perhaps something in VLC is not working, but ffmpeg / ffplay usually works
                                  • on linux OS should be able to do it using apt-get ffmpeg
                                  • for other OS you can find direct download : https://www.ffmpeg.org/download.html

                                play the video on the host machine (replace voxl2-ip with actual ip address)

                                ffplay rtsp://<voxl2-ip>:8900/live

                                  Typically hires is the only pipe with encoding enabled by default, but in this case tracking is being used. Can you make sure encoding is enabled for the tracking camera in voxl-camera-server.conf ?

                                  Or, can you just see if hires_enc is working in QGC first? That's what we ship by default on a fresh install hires_enc to QGC should by enabled by default.
