Gstreamer error: Streaming video to QGC over LTE
-
@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.

I have configured Tailscale as a priority network:
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:
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:
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.

No worries, I reverted the voxl-streamer configuration to its original settings, restarted it, then updated and restarted voxl-mavcam-manager.conf.
Afterwards, I attempted to set the RTSP stream to the specific IP address:
When I checked voxl-streamer, the output showed the following:
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
-
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
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.

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
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

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? -
