Customize M3U8 Metadata for HLS Streams

[LegendaryFire]

The ability to add or customize metadata for the M3U8 streams would be a great feature to have. I'm trying to live stream gameplay to my Plex server, but the required tvg-id is missing so it won't recognize the media in the playlist. I've tried building a web server with Flask to interpret the M3U8 data and forward it to Plex but unfortunately it since it's not coming from the same domain as Restreamer, it won't work. Another solution would be to expose a raw RTSP stream.

Even if it was possible by passing URL parameters to the HLS stream would be suffice.
