April 2026 monthly summary for ossrs/ffmpeg-webrtc: Focused on robustness and data integrity in media parsing and memory safety. Delivered a critical bug fix in mov_read_dops to guard against uninitialized extradata for opus, preventing use of stale data and potential crashes. Implemented a read size validation that ensures extradata is fully populated or errors out if insufficient data. This work improves stability and reliability of WebRTC streaming pipelines and reduces crash surface in demuxing code.

March 2026 monthly summary: Improved reliability and memory safety in MOV-based video parsing across FFmpeg/FFmpeg and ossrs/ffmpeg-webrtc. Delivered targeted fixes to prevent crashes on crafted inputs and to avoid memory corruption in 32-bit builds. These changes reduce production risk and improve stability for media workflows.

February 2026: Implemented a safety reinforcement in the FFmpeg STSD parsing path by resetting sc->stsd_count before parsing entries, preventing out-of-bounds writes. Linked to commit a58cb16e27bc0c32906cfb3de36e4a495c0a8602. This fix improves stability and reliability of media parsing across FFmpeg deployments.
