- Implement graceful degradation for congestion handling with configurable thresholds
- Refactor audio relay track updates to be async to prevent deadlocks
- Add timeout-based supervisor stop during quality changes
- Optimize buffer pool configuration and cleanup strategies
Significantly increase message pool, channel buffer, and adaptive buffer sizes to better handle quality change bursts. Adjust timeouts and intervals for improved responsiveness.
This change replaces all instances of GetConfig() function calls with direct access to the Config variable throughout the audio package. The modification improves performance by eliminating function call overhead and simplifies the codebase by removing unnecessary indirection.
The commit also includes minor optimizations in validation logic and connection handling, while maintaining all existing functionality. Error handling remains robust with appropriate fallbacks when config values are not available.
Additional improvements include:
- Enhanced connection health monitoring in UnifiedAudioClient
- Optimized validation functions using cached config values
- Reduced memory allocations in hot paths
- Improved error recovery during quality changes
- Add server stats reset and frame drop recovery functions
- Implement global audio server instance management
- Add WebRTC audio track replacement capability
- Improve audio relay initialization with retry logic
- Enhance quality change handling with adaptive buffer management
- Add global helper functions for audio quality control
- Replace mutex-protected refCount with atomic operations in ZeroCopyFramePool
- Implement chunk-based allocation in AudioBufferPool to reduce allocations
- Add proper reference counting with atomic operations in ZeroCopyAudioFrame
- Optimize buffer pool sizing based on buffer size
