Streaming local Webcam in a Linux machine, and acessing it when on vacations - which protocol to choose? (self.selfhosted)

I want to configure a local webcam to stream (and possibly record) a live feed open to the internet, and acess it half-world away while traveling, using FOSS only acessing it via Android VLC

This guide was quite comprehensive; however the packages for nginx-rtmp are quite abandoned in arch linux. So I thought maybe WebRTC could be an alternative - the communication itself should be encrypted, which WebRTC seems to do; however, I still can't figure out if VLC will handle this well

Also, it seems that I might need to self-host a VPN to achieve this? What are my options? Has anyone else done this ?

I'd go for HLS due to its simplicity: just files over http(s). VPN or not - depends on your network. If your machine is accessible from the internet, just putting the files into a webserver subdirectory with a long random path and using https will be secure enough for the usecase. Can be done with an ffmpeg oneliner.

The downside of HLS is the lag (practically -- 10s or more, maybe 5 if you squeeze it hard). It is in no way realtime. Webrtc does it better (and other things too), but it is also a bigger pain to set up and forward.

Also, just in case, test that the webcam works fine if left active 24/7. I had (a cheapo) one that required a powercycle after a week or so...
