Up front, so there's no confusion: the app I'm describing (Nightmare TV) is a player only. You bring your own M3U / Xtream Codes playlist — it ships with no channels and no content. This post is about the playback engineering, not about where streams come from. Think "VLC for IPTV," not a content service.
The problem that started it
I watch a lot of live content on my PC — sports, mostly. And every IPTV player I tried on Windows fell into one of two buckets:
An Android app running in an emulator. TiviMate and the good mobile players are Android-only, so on a desktop you end up in an emulator or a VM. Input lag, no real HDR path, fans spinning.
A thin ExoPlayer / libVLC wrapper. These run natively, but most of them treat HDR as "pass the HDR10 metadata to the display and hope." On an SDR panel — or even a lot of HDR panels — bright skies in a football match blow out to a flat white blob, and 4K HEVC with a DTS track stutters because the decode path isn't doing what you think it is.
