Thanks, and sadly you are indeed correct. Id at least need to upgrade to a VPS. My shared A2 hosting has already let me get away with a LOT despite technically crossing several "no-no" rules (I do host MP3s and some videos of my own stuff, and I have tons of photos). They have said they are OK with that, because I've been good about not hogging server bandwidth. But they politely explained that besides it being against the terms of service, it could easily cause my bandwidth resource limit to be exceeded, resulting in automated thottling, and potentially causing instability for other users of the same shared server.
I could try it from a server at home. My "upload" speed is only 25MBps though. So maybe if I kept the video portion down to a small 320 x 240 view (which means it would get blurry if a visitor expanded much), but kept the audio quality good, maybe I could serve a couple dozen viewers. But that would be pushing it.
My budget demands that I play the game of getting multiple year hosting at promo prices, and taking advantage of the lower cost of shared hosting deals. About the only "extravagance" I opt for is to be able to host multiple domains. But as everything I do these days is a labor of love, it will have to do.
Maybe I'll try that NGINX sometime just for fun. Give me an excuse to tinker with that XAMPP install I've barely messed with. But its starting to sound like I'll have to settle for testing the live streaming waters with Youtube or Vimeo or something like that. Especially as this is unlikely to be a permanent endeavor. As soon as vaccines are available and things start getting close to "normal" again, I'll much prefer actually playing for people again.
Anyway, thanks for the tip! Good thing i checked with my hosting company before digging into this too deeply!
