…erConfig - Integrate AudioEncoderConfig for audio configuration management - Implement hardware sample rate detection using AudioFormat.SAMPLE_RATE_UNSPECIFIED on API 24+ - Configure MicrophoneMode.SYNC for better audio/video synchronization in long sessions - Add fallback to configured sample rate for older Android versions - Enhance logging with audio configuration details This addresses buffer mismatch issues that cause audio degradation in extended streaming sessions.
…Manager Integrated AudioCaptureManager and BufferReleaseManager into RtmpStreamManager for comprehensive audio pipeline lifecycle management: - Added dependency injection for both managers in constructor - Initialize AudioCaptureManager in startPreview() with proper config - Reset BufferReleaseManager in startStream() for new sessions - Release AudioCaptureManager in stopPreview() for cleanup - Release both managers in release() for complete resource cleanup This integration ensures: - Proper microphone resource management throughout streaming lifecycle - MediaCodec buffer release to prevent 25-40 minute crash pattern - Clean resource cleanup preventing memory leaks - Extended session stability (4+ hours) per spec requirements Follows established patterns from RtmpStreamManager including Hilt @singleton, proper error handling, and comprehensive logging. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

- Add audioHealthMonitor.startMonitoring() in onConnectionSuccess() - Add audioHealthMonitor.stopMonitoring() in stopStream() - Add audioHealthMonitor.release() in release() This ensures AudioHealthMonitor automatically starts tracking buffer health, latency, and memory metrics during streaming sessions and properly stops/releases resources when streaming ends.
