@Kris What do you see with systemctl status voxl-streamer?

@tom This is what I see.

@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.
