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.

• 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

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

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

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:

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

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",

        "enable_auto_ip":       true
}

You should be able to pull up the stream if the service is running, no need to run it manually like that

{            
        "input-pipe":   "tracking",

        "port": 8900

Then when I go to run voxl-streamer, it works at first but when I open VLC it does not work.

voxl:~$ voxl-streamer -i tracking

I am not sure why I am not able to do this.

192.168.110.152 is my current Seeker IP.
192.168.110.159 is my current host PC IP.

What I would really like to do is connect my stereo stream with QGroundControl instead of VLC. But I haven't even gotten VLC to stream it yet....
