You are using z2m with a Xiaomi gateway?

Increase log level for rtsp module to trace and show result logs.

"i/o timeout" it's usual connection error. It can be useful if it connected to "start from CONN state". But I can't see this in your logs.

You have to try to add it yourself. It shouldn't be difficult. https://github.com/AlexxIT/XiaomiGateway3?tab=readme-ov-file#add-new-device

Players can't play HTML files. They are for browsers only

That means the stream from the camera didn't start in 3 seconds.

I don't know any reason for using HLS as FFmpeg input. It's not real time format

Your tests wrong. HLS just can't be only working format.

All this links wrong. I don't know where you get them.

`.html` links only for browser
