Multi-Platform IPTV Player Needed -- 2

I need a single, consistent IPTV media-player application that I can install on Smart TVs, mobile devices and regular computers. The player must open both M3U playlists and Xtream-Code logins without any external converter, then organise the content into Live TV, series and movies automatically.

Core functionality
• Live TV playback with fast channel zapping
• Full catch-up (time-shift) on channels that provide it
• Integrated EPG grid and now/next info, refreshed from the playlist source
• Category filtering and search across live, series and films
• Simple remote-control navigation on TVs, plus touch gestures on phones/tablets
• Reliable reconnection logic for unstable streams

Target platforms
– Smart TVs (Samsung Tizen and LG webOS are my main focus, but a generic Android TV build is welcome)
– Android and iOS phones/tablets
– Windows or cross-platform desktop (Electron, Flutter, or similar—whichever you prefer)

I am open to a custom build or a heavily-customised open-source base, provided the final product carries my branding and can be side-loaded or submitted to the relevant stores.

Acceptance will be based on:
1. Clean playback of my test M3U and Xtream accounts on each platform.
2. Working EPG and catch-up on channels that support it.
3. Smooth UI/UX on TV remotes and touch screens.

Please outline the framework you would use, how you will deliver each platform build and the estimated timeline for a first functional release. Source code hand-over and basic deployment instructions are expected at project close.
