Cross-Platform MP4 Player App

I need a straightforward way to turn a single MP4 file into a dedicated video-player app that works on both iOS and Android. The app’s sole purpose is to let users play, pause, seek, and adjust volume for this embedded video; no editing or conversion features are necessary.

You are free to choose the tech stack—Flutter, React Native, Swift/Kotlin, or any other approach—so long as you can deliver store-ready builds for Apple’s App Store and Google Play. Because the video is bundled with the app, playback must work entirely offline.

Deliverables
• Complete source code with the MP4 correctly integrated
• Release-ready IPA and APK/AAB files, plus project files for future updates
• Simple splash screen and app icon placeholders
• Clear, step-by-step instructions for signing and submitting to both stores

Acceptance criteria
• App opens to a single screen showing the poster frame
• Standard controls (play/pause, scrub bar, volume) work smoothly on current iOS and Android versions
• Video plays instantly without buffering in airplane mode
• Builds pass App Store and Google Play review without issues

If you can propose lightweight extras such as subtitle toggling or Chromecast as optional add-ons, feel free to outline them in your bid. I’m ready to get started as soon as I find the right developer.
