Streaming Stereo Camera

@Kris It looks like voxl-streamer is already running in the background and then you're running it again in the terminal manually, hence the existing instance of voxl-streamer found, attempting to stop it

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

Kris

@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:

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 ?

I am not able to view any video when executing the voxl-mavcam-manager either.

@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?

Kris

@tom
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.

tom

@Kris

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

Kris

@tom Thank you so much, I just found it and I will try it.

Kris

@tom
I am sorry, it is still not working....

Kris

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

Kris

@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.
