Address 5 critical issues found in comprehensive code review: 1. Opus Encoder Configuration Failures (CRITICAL) - Split encoder settings into critical vs non-critical - Critical settings (bitrate, VBR, FEC) now fail initialization on error - Non-critical settings (complexity, DTX) log warnings but continue - Prevents silent audio quality degradation from misconfigured encoder 2. V4L2 Sample Rate Detection Error Reporting (CRITICAL) - Add specific error messages for different failure modes - Distinguish permission errors, device not found, and no signal - Validate detected sample rates are in reasonable range (8-192kHz) - Improves debuggability when HDMI audio detection fails 3. Mutex Handling in ALSA Error Recovery (CRITICAL) - Refactor handle_alsa_error() to NEVER unlock mutex internally - Caller now always responsible for unlocking after checking return - Eliminates complex mutex ownership semantics that caused deadlocks - Consistent lock/unlock patterns prevent double-unlock bugs 4. Async Audio Start Error Propagation (CRITICAL) - Make SetAudioOutputEnabled/SetAudioInputEnabled synchronous - Add 5-second timeout for audio initialization - Return errors to caller instead of only logging - Revert state on failure to maintain consistency - Users now get immediate feedback if audio fails to start 5. CgoSource Race Condition (CRITICAL) - Hold c.mu mutex during C function calls in ReadMessage/WriteMessage - Prevents use-after-free when Disconnect() called concurrently - Lock order (c.mu -> capture_mutex) is consistent, no deadlock risk - Fixes potential crash from accessing freed ALSA/codec resources These changes eliminate silent failures, improve error visibility, and prevent race conditions that could cause crashes or audio degradation. |
