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

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 ?
