android-video-capture

What problem does it solve?

Building a reliable camera screen is hard because lifecycles, permissions, and recording/capture flows easily break across devices, orientations, and UI recompositions.

Core Features & Use Cases

• Lifecycle-aware CameraX setup in Android apps using ProcessCameraProvider so preview and capture start/stop safely with the UI lifecycle.
• Video recording to MediaStore with VideoCapture and MediaStoreOutputOptions, including optional audio support for MP4 gallery-ready videos.
• Photo capture to MediaStore with ImageCapture and correct ContentValues for gallery placement.
• Simultaneous preview + video + photo, with runtime capability checks via CameraInfo.isUseCaseCombinationSupported() for older devices.
• Camera controls including dynamic front/back selection and torch/flashlight control with state observation.
• Safety and quality guardrails like explicit QualitySelector, strong references to active recordings, and anti-pattern fixes for common IllegalStateException and finalize issues.

Quick Start

Use the android-video-capture skill to implement a Compose camera preview that records an audio-enabled video to the gallery and captures photos with torch support.
