RecorderX

A resilient, open-source screen recorder featuring hardware-accelerated encoding, zero telemetry, and automated fallback protection.

---

RecorderX is an application designed for high-fidelity screen capture.

Versions

• v3.0.1 (Latest):
  • Performance & Core Fixes (Merged #8):
    • Fixed Android 14/15/16 and OnePlus recording failure by removing incompatible VirtualDisplay presentation flags.
    • Fixed 1 FPS AV1 encoding lag by enforcing hardware-accelerated MediaCodec selection.
    • Eliminated microphone audio stutter via PCM buffer allocation pooling.
    • Fixed blurry 4K/1080p video outputs with dynamic BPP minimum bitrate calculation.
    • Fixed video player start delay by zeroing CODEC_CONFIG buffer sizes.
    • Fixed service memory leaks during lifecycle teardown (onDestroy).
  • Floating Controls & Brush Tools:
    • Added Independent Move Tool to select and drag individual drawn shapes around the screen.
    • Reorganized Brush Toolbar into a compact 2-row/3-row grid with a dedicated frosted drag handle.
    • Improved White 'X' (minimises toolbar, keeps drawings locked on screen) and Red 'X' (clears drawings & exits).
    • Tapping floating bubble while minimised directly re-opens the Brush Toolbar.
  • Notification Panel & System Integration:
    • Added Hide / Show Floating Bubble action button directly in the active recording notification panel.
    • Replaced generic open folder with "Open Last Recording", launching the system chooser for ZArchiver, VLC, Gallery, etc.
  • UI & Quality-of-Life:
    • Auto-dismissed "Swipe Here" tutorial hint on the 3rd app launch.
    • Fixed Output Template Box border color to dynamically match the active accent theme across all states.
• v3.0.0: Title Bar Swipe Gesture Theme Customizer (with custom onboarding and pulsing logo), Floating overlay controls, real-time screen brush tools, compact MediaStyle notification buttons, and compilation transition to Java 21.
• v2.0.1: Android 14 background activity compliance fixes.
• v2.0.0: Live-Reboot Watchdog, Encoder Fallback Mechanism, and System + Mic Audio Recording.
• v1.1.0: 4K/120FPS Support, AMOLED Lavender UI, and Live Thumbnail Notifications.
• v1.0.0: Initial stable release with H.264/HEVC support.

Core Features

• High Resolution Capture: Support for 4K (UHD), 2K (QHD), and standard definitions.
• Enhanced Framerates: Native support for 90 FPS and 120 FPS recording modes.
• Advanced Codecs: Integrated support for H.264 (AVC), H.265 (HEVC), and AV1.
• Audio Management: Capture of Microphone, System audio, or both (Mic + System) simultaneously.
• Post-Capture Feedback: Automated thumbnail generation and system notification on session completion.
• Complete Privacy: Operates entirely offline with absolutely no internet permissions or telemetry.
• Floating Control Overlays: Access quick pause, resume, and stop recording actions floating over other applications.
• Screen Brush & Drawing Tool: Sketch and highlight directly on your screen while recording is active.
• Swipe-to-Recolor Theme Customizer: Instantly cycle between 12 distinct AMOLED-compatible neon accent colors by swiping left/right across the top title bar.
• Compact MediaStyle Notifications: Leverages custom text action drawing so control buttons remain functional and visible even in Android 14 collapsed/compact notification views.

Advanced Capabilities

• Live-Reboot Watchdog: Features a self-healing encoder loop that seamlessly catches encoding failures and restarts the session internally, ensuring Android 14+ MediaProjection tokens are never invalidated.
• Custom ROM & GSI Compatibility: Bypasses faulty hardware checks found in standard Android environments, providing stable recording on spoofed or heavily modified custom ROMs.
• SoC Graceful Degradation: Automatically detects hardware bottlenecks (like AV1 encoding limits on weaker CPUs) and triggers encoder fallbacks without crashing the application.
