April 2026 monthly summary for ossrs/ffmpeg-webrtc. Focused on expanding test coverage and reliability for libavutil and FATE, delivering comprehensive testing enhancements across buffer management, HDR dynamic vivid metadata, tdrdi display information, and timestamp handling. Implemented end-to-end FATE tests that exercise memory edge cases and OOM scenarios, achieving significant coverage gains and early regression detection. These efforts reduce memory-related defects, improve stability in production builds, and establish a robust foundation for HDR and display-related features.

March 2026: FFmpeg/FFmpeg delivered meaningful stability improvements, expansive test coverage, and targeted safety fixes across core utilities, codecs, and filters. The month focused on reducing risk in Stereo3D handling, expanding FATE-driven validation, and tightening edge-case parsing to improve reliability in production builds.

February 2026 — FFmpeg/FFmpeg: Key feature delivery and test-coverage improvements for film grain parameters in AV1 and H.274. No major bugs fixed this month. Overall impact: significantly improved regression safety and test quality for codec parameter handling, enabling safer changes and faster release readiness. Technologies demonstrated: FATE-based unit testing, libavutil test scaffolding, and AV1/H.274 film grain parameter modeling.
