Streaming over cellular data to OBS on Wi-fi network

Hello all,

I am a storm chaser and I am currently trying to discover some options to send a video stream over cellular data to a Linux computer on a different wireless network. I understand this will require some use of VPN which I also am not very informed in. Does anyone have any suggestions or know a step-by-step resource to set this up?

My goal is that if my cellular stream cuts out that OBS will be able to continue my stream until my phone can send video from the cellular network again.

Any assistance is appreciated. Thank you!

For others to chime in with more targeted suggestions:
- I'd back up a bit and ask what you are trying to accomplish (more so than described above). For example, or you planning for OBS to composite (change) the video feed you are sending it via cellular? if not, why not send your mobile video feed direct to stream provider (CDN), and OBS sending a backup stream the CDN which can be set to auto fail-over to backup stream?
- Sending a video feed to another computer over the internet does NOT require VPN. I'm not suggesting not using a VPN, but that will involve overhead, and there are other ways to secure the connection (certificates, etc). In that upload cellular bandwidth is NOT as stable as a decent wired Internet connection, therefore if you are trying to maximize usable bandwidth, VPN overhead might be something to avoid. maybe.
- What EXACTLY do you mean by "Linux computer on a different wireless network" ?

If I understand you correctly, you want to use your phone in the middle of who-knows-where as a live source in OBS, which is running safely at home. Automatic or manual switching in OBS is a different question, not covered here. Did I get it right?

If so, then you might look at this app:

I already knew about it, so it didn't take much googling to find a TON of tutorials and examples. Now that you know too, so can you. :-)

The protocol that it uses isn't the lowest latency, so I use something different in my studio, but it's designed specifically to survive the internet, while my preferred studio one isn't.
