Entrypoints, the audio entrance to Roon, made the move to HiRes!

I think you can inject metadata with ffmpeg.
I would like to know if you can implement a way to use entrypoints to re-encode HLS radio streams that are not supported by Roon.
Now, I am using ffmpeg and Icecast to send it to Roon, but it would be great to have this as extension.
Thanks !
