Fully migrated to API 101; fixed WhatsApp video calls and Snapchat; added live streaming functionality.

Android CamSwap is a virtual camera module based on the Xposed framework. It intercepts Android system camera preview and requests, replacing the preview with a user-specified video. This project uses a modern Android development stack (Kotlin, Jetpack Compose) and features a cross-process data transmission mechanism based on ContentProvider. It's compatible with file permission isolation on high-version Android (11+). Implementation details for older v2.0 and prior versions are available in historical commits. The current branch has been refactored with structural improvements. ✨ Main Features - Full API Support: Simultaneously supports Camera1 (Camera) and Camera2 (CameraDevice) APIs. - Video Replacement Preview 🎥: Seamlessly replaces the camera preview with a specified MP4 video. - Audio Replacement 🎤: Option to play custom MP3 audio files or synchronize with the replacement video. - Notification Bar Real-time Control: - ⏭ Switch to the next/previous video. - 🔄 Quickly adjust video rotation (+90° / -90°). - 🎲 Random playback mode. - Auto-rotation Handling: Reads rotation metadata from the video and renders it correctly using OpenGL ES—no manual adjustments needed. - Cross-process Configuration Sync: - Primary Path: ContentProvider IPC (no storage permission required for target apps). - Fallback Path: Direct file reading + application cold-start warm-up, fully resolving configuration unavailability during cold starts. - Target App Filtering: Specify apps where the module should activate. - Modern UI: Management interface built with Material Design 3 and Jetpack Compose. - Live Streaming: ExoPlayer + extensions, supporting RTSP/HLS/DASH and RTMP/RTP protocols. 📱 Requirements - Android Version: Android 8.0 (API 26) and above (Android 11+ recommended). - Root Permission: Required. - Xposed Framework: LSPosed recommended (Zygisk and Riru versions supported). Note: Versions 2.5+ no longer support LSPosed 1.0. 🚀 Installation & Usage 1. Install the Module - Download the latest Release APK. - Install it on your Android device. - Enable the module in the LSPosed manager. - Select the scope: - Check the target apps you want to affect (e.g., Camera, WeChat, Douyin/TikTok, etc.). - Restart the target app's process. 2. Configure Materials - Open the CamSwap app and grant necessary file read/write permissions. - Import your MP4 video files on the "Manage" page. - Go to the "Settings" page to select the default video, configure audio replacement, enable notification bar controls, etc. 3. Start Using - Open any app that uses the camera. The preview will be replaced with your selected video. 💡 Tip If the video orientation is incorrect, use the rotation button in the notification bar or set the rotation offset manually in settings. ⚠️ Disclaimer This project is for security research, software testing, and educational purposes only.
