Auto-plays with good buffering + +## Future Enhancements + +Potential additions: +- [ ] Video trimming/editing +- [ ] Slow motion playback +- [ ] Frame-by-frame navigation +- [ ] Screenshot from video +- [ ] Share video option +- [ ] Delete video option + +## Files + +- `example/lib/video_playback_screen.dart`: Main video player screen (200+ lines) +- `example/lib/main.dart`: Integration in main example +- `example/lib/native_recording_example.dart`: Integration in alternative example +- `example/pubspec.yaml`: Added video_player dependency diff --git a/android/build.gradle
