efficient_video_recorder 0.1.2

High-efficiency camera video recorder for Flutter. Optimized for low battery usage and zero thermal throttling with CameraX on Android and AVFoundation on iOS.

0.1.2

• Fix black camera preview on device rotation when recording or switching orientation:
  • Attach surfaceProvider to Preview after binding to lifecycle for reliable surface negotiation.
  • Dynamically update targetRotation on Preview and VideoCapture in-place without resetting capture sessions.

0.1.1

• Fix camera preview freezing or stopping after device rotation or resizing:
  • Switched PreviewView to ImplementationMode.COMPATIBLE (TextureView) to prevent hardware surface drops on configuration changes.
  • Guarded detachSurfaceProvider against race conditions during view recreation.
  • Added automatic display rotation tracking via ComponentCallbacks2 on Android.
  • Made setTargetRotation auto-detect current display rotation and seamlessly re-bind/refresh preview surfaces when orientation changes.

0.1.0

• Initial open source release of efficient_video_recorder.
• Android:
  • Purpose-built CameraX 1.5.x module binding strictly 2 streams: Preview and VideoCapture<Recorder>.
  • Zero-copy hardware preview via SurfaceView (PreviewView.ImplementationMode.PERFORMANCE), bypassing the Flutter GPU texture-render loop.
  • Capped 24 fps capture mode to cut sensor & ISP workload by 20–30%.
  • Explicit bitrate presets: SD 480p (2.5 Mbps), HD 720p (4.5 Mbps), FHD 1080p (8.0 Mbps).
  • Software video stabilization disabled by default to eliminate gyro sensor polling & warping power drain.
  • Event-driven finalize callbacks (VideoRecordEvent.Finalize).
• iOS:
  • AVFoundation capture pipeline using AVCaptureSession and AVCaptureMovieFileOutput.
  • Native preview layer integration.
• Flutter:
  • Modern, lightweight EfficientVideoRecorderController with lifecycle management.
  • EfficientVideoPreview widget with gesture transparency so parent tap gestures work out-of-the-box.
