I actually meant the nginx-ts module. With this module, you just send an MPEG2-TS stream to nginx from ffmpeg, and the -ts module handles creating all the HLS metadata etc. No reencoding occurs. I used this setup briefly before switching to SRT, so didn't test it thoroughly, but it seemed to work well, other than the usual latency of HLS.

Thanks for your detailed email as there is a lot of good info there.
