bilibili/ijkplayer ? reverse-engineered prompt

Build me a cross platform video player for Android and iPhone that can play local files and online streams smoothly, even on weaker devices.

I want it to feel like a simple native player app, with basic controls like play, pause, seek, fullscreen, and volume, and it should handle common video formats well. Use hardware decoding when available so playback is fast and battery friendly, and fall back cleanly if not. Please also include a small demo app for both Android and iOS so I can test it right away, and make it easy to plug into my own app later.

If anything needs current setup steps or build details, look up the latest docs online and follow the project’s existing build approach.
