Hi @dimdallas,
I just tested some setup I was working on:
Windows 10 (20H2, build 19042.746) with WSL2 (windows subsystem for linux) with Ubuntu 18.04 LTS.
I installed NGINX (with rtmp module) on the Ubuntu (running in WSL2), example config, and on that same Windows machine watched the stream with ffmpeg/ffplay:
ffplay -fflags nobuffer -i "rtmp://192.168.2.118/live/z1"
z1 -> stream key.
The ffmpeg/fflpay works also for the “THETA RTSP Streaming Plug-In”.
Since this thread is about Unity, one could theoretically use FFMPEG as an plugin (dll) in Unity and project/pipe ffmpeg/ffplay output on a texture.
