I did some testing. It turns out the vrchat stream player will play a regular, bounded mp3 file just fine as pure audio (with a blank video), without having to transcode to aac and wrap with a mp4 file. That's not a bad way to do a dance night then, just host a bunch of mp3 files somewhere and stick the urls in the video player playlist.

Unfortunately, the r/a/dio icecast stream doesn't work, even with the 'live' player mode. It'll buffer 100ms of audio, play it in a little burst of static, then shut off when vrchat's stream player tries to sync up the byte ranges or something, repeated every few seconds.

Thus, for truly live music I think you'd have to still use nginx-rtmp to transcode and chunk up the audio into a real HLS stream. but that's straightforward enough.

Thanks for keeping r/a/dio running. A few of us were listening to it during the last new years in vrchat, was comfy. I'm considering making a vrchat world to restream r/a/dio in this year, and also the december toradora stream.
