## Rawdha R · 2024-10-07 06:57:09 UTC

I have connected QGroundControl (QGC) to my VOXL 2 using a 5G modem and Tailscale VPN. However, I am unable to stream the camera feeds.

Additionally, I tried using VLC, but I’m not receiving the video stream. Here are the error messages I am encountering in both QGC and VLC:

@Rawdha-R this looks like an issue on your computer, not on the VOXL2. The error states you are missing a plugin of gstreamer - have you installed gstreamer on your parent computer properly?

@Rawdha-R Like Zach said, make sure you've installed the required dependencies for QGC: https://docs.qgroundcontrol.com/master/en/qgc-user-guide/getting_started/download_and_install.html#ubuntu

@tom even if he resolves the gstreamer errors, wont this also not work because wwan0 is not in network_preferences?

@Rawdha-R see here https://forum.modalai.com/topic/3660/streaming-video-to-qgc-over-lte?_=1728315665042

@groupo Good call, another thing worth investigating

## Reply by Zachary Lowell 0 · 2024-10-07 20:44:28 UTC

Hi @Rawdha-R I think there is just an interface error you are doing incorrectly with your tailscale setup.

I am able to connect over both 4g and 5g via tailscale to both PX4 from QGC and to VLC from voxl-streamer.

![Screenshot 2024-10-07 at 3.37.19 PM.jpg](https://forum.modalai.com/assets/uploads/files/1728333864464-screenshot-2024-10-07-at-3.37.19-pm-resized.jpg) ![Screenshot 2024-10-07 at 3.37.26 PM.jpg](https://forum.modalai.com/assets/uploads/files/1728333864734-screenshot-2024-10-07-at-3.37.26-pm-resized.jpg) 

What services do you have running on your voxl2? Do you have voxl-camera-server and voxl-streamer both configured? Are both the voxl2 and the parent computer you are trying to view the stream with both on the same VPN on tailscale? Can you ping the voxl2 from the parent computer over tailscale and vice versa?

@Zachary-Lowell-0 
@tom @groupo 

The setup is working well. I successfully pinged both the VOXL drone and the parent computer:

Additionally, I managed to stream using MVP, and it functioned:

As for the wwan0, I have confirmed that an IP address is displayed:
![Screen Shot 2024-10-08 at 11.16.00 AM.png](https://forum.modalai.com/assets/uploads/files/1728371767633-screen-shot-2024-10-08-at-11.16.00-am-resized.png) 

Both voxl-streamer and voxl-camera-server is enabled and running: 
![Screen Shot 2024-10-08 at 11.27.24 AM.png](https://forum.modalai.com/assets/uploads/files/1728372454456-screen-shot-2024-10-08-at-11.27.24-am.png) 

However, I'm still encountering some difficulties with streaming on VLC and QGroundControl (QGC). I've installed the necessary GStreamer dependencies, but I continue to receive errors when attempting to stream on both platforms.

I have following the instructions in this link to install gstreamer properly: 
https://gstreamer.freedesktop.org/documentation/installing/on-linux.html?gi-language=c 

P.S: I'm using Ubuntu 22.04.5 LTS

@Rawdha-R Can you try adding `tailscale0` to the top of the list in `/etc/modalai/network_interface_preferences.txt` and power cycling your voxl?

## Reply by tom (ModalAI staff) · 2024-10-08 16:41:31 UTC (in reply to tom)

@tom Like this:

```
# List the order of priority of network interfaces here.
# Top is most important
# Bottom is least important

tailscale0
tun0
eth0
usb0
wlan0
wwan0

# end
```

## Reply by Zachary Lowell 0 · 2024-10-09 15:11:49 UTC

@Rawdha-R please go into voxl-streamer config /etc/modalai/voxl-streamer.conf and change the auto ip to false and then change the url to match the IP address of that in your tailscale IP. I believe what is happening right now is voxl streamer might be prioritizing a different IP as Tom mentioned above.

Zach

@Zachary-Lowell-0 @tom 

I have configured Tailscale as a priority network:
![Screen Shot 2024-10-14 at 10.45.19 AM.png](https://forum.modalai.com/assets/uploads/files/1728888370906-screen-shot-2024-10-14-at-10.45.19-am.png) 

While setting up the voxl-streamer (located at /etc/modalai/voxl-streamer.conf) with the new URL, I noticed that the parameters auto_ip and url were missing:

![Screen Shot 2024-10-14 at 10.47.18 AM.png](https://forum.modalai.com/assets/uploads/files/1728888446059-screen-shot-2024-10-14-at-10.47.18-am.png) 

I have added both parameters, setting auto_ip to false and updating the url with the Tailscale IP address and I checked the voxl-streamer and found that the stream value is still showing as 127.0.0.1:
![Screen Shot 2024-10-14 at 10.12.27 AM.png](https://forum.modalai.com/assets/uploads/files/1728888523360-screen-shot-2024-10-14-at-10.12.27-am-resized.png)

After these adjustments and power cycling the device, Additionally, I attempted to check the connection in QGroundControl and VLC, but I'm encountering some errors:

@Rawdha-R those parameters are in voxl-mavcam-manager.conf not voxl-streamer. Apologies for mispeaking. Please remove those from voxl-streamer as it is most likley causing it to crash and then restart voxl-streamer and voxl-mavcam-manager.

## Reply by Rawdha R · 2024-10-15 08:41:42 UTC (in reply to Zachary Lowell 0)

@Zachary-Lowell-0 
@tom 

No worries, I reverted the voxl-streamer configuration to its original settings, restarted it, then updated and restarted voxl-mavcam-manager.conf.

![Screen Shot 2024-10-15 at 11.11.47 AM.png](https://forum.modalai.com/assets/uploads/files/1728977109503-screen-shot-2024-10-15-at-11.11.47-am.png) 

Afterwards, I attempted to set the RTSP stream to the specific IP address:
![Screen Shot 2024-10-15 at 10.54.32 AM.png](https://forum.modalai.com/assets/uploads/files/1728977149362-screen-shot-2024-10-15-at-10.54.32-am.png)

 When I checked voxl-streamer, the output showed the following:

![Screen Shot 2024-10-15 at 11.16.29 AM.png](https://forum.modalai.com/assets/uploads/files/1728977343344-screen-shot-2024-10-15-at-11.16.29-am-resized.png) 

This is the errors that I got from Qground:

@Rawdha-R Are you able to pull up the stream in something like VLC? Trying to determine if it is indeed a QGC issue

## Reply by Rawdha R · 2024-10-17 19:56:07 UTC (in reply to tom)

@tom 
No, I’m not able to pull up the stream in VLC, I’m getting this error:

@Rawdha-R Do you have this same issue if you try to stream over just wifi with no vpn?

## Reply by Rawdha R · 2024-10-21 10:37:50 UTC (in reply to tom)

@tom 

I think I need a wifi dongle for it and I haven’t tried it with wifi.

## Reply by groupo · 2024-10-24 15:06:05 UTC

I am also having issues now seeing my stream in VLC. It works as expected in QGC but I get similar errors to @Rawdha-R. 

I had this working before in August, in fact I reverted from 13.3. to 1.3.0 just to see if that was an issue, but it persists. I will include some screenshots of my process below ![Screenshot from 2024-10-24 10-56-12.png](https://forum.modalai.com/assets/uploads/files/1729781972515-screenshot-from-2024-10-24-10-56-12.png) 

You can see in the next screenshot below that the video is being received by QGC

@tom wwan0 is in my network interface file, the default URI is set to that of the cellular modem, but of course auto_ip is set to true as well. Voxl-my-ip returns that of the cellular modem. I am a little confused though about how the config of mavcam-manager determines the behavior of voxl-streamer. In the diagram on the docs they seem decoupled.

I have included the verbose vlc log at the end of this file as well.

@Rawdha-R @tom 

SO, I used ffplay and was able to see the stream successfully. A quick google about vlc/rtsp brought up many issues in the community after some recent updates. I am not sure how I was able to do this before and cannot now, but I did find a fix for windows

https://www.reddit.com/r/reolink/comments/yzhlxp/found_a_solution_for_rtsp_blackno_video_in_vlc/#:~:text=In%20VLC%2C%20under%20the%20Tools,video%20stream%20in%20VLC%20player.

In case that link is ever deleted, I will paste the instructions here
"In VLC, under the Tools menu, go to Preferences (or Ctrl+p), open the Input/Codecs tab, and at the bottom in the Network area, the selection for "live555 stream transport" should be moved from "HTTP (default)" to "RTP over RTSP (TCP)". This worked, I can now view the video stream in VLC player."

This resolves the RTSP stream for windows. Those config options are not available in the linux version of VLC but I did see some config options you can build VLC with. I did not venture too far down that path

@tom 
The issue still persists for me. Do you think my setup could be causing the problem? I have an M1 Mac processor, and I'm using a virtual machine with UTM(Visualizer). Could that be causing any limitations? Should I try a different setup, and do you have any recommendations?

P.S. I am currently working with the Drone Sentinel VOXL 2 and the drone is connected via LTE but without Wi-Fi, because there is no wifi dongle.
