Hunlongyu/ZY-Player ? reverse-engineered prompt

Build me a clean cross platform desktop video player app that feels simple and nice to use, like a modern media library for finding and watching online video sources.

I want it to work on Windows, Mac, and Linux, with a polished interface and no ads. It should let me add my own video sources, import and export them, search across all sources at once, and browse in either poster view or list view. Please include IPTV and live TV support, playback history that jumps back to where I left off, a favorites section for keeping track of shows, and a way to export download links. It should also support a compact mini mode, third party player playback, dark and light themes, and show useful details like ratings when available.

Make the player feel smooth, with keyboard shortcuts for common actions like play, pause, seek, next episode, volume, fullscreen, and speed changes. If you need to look up current docs online, go ahead.
