During January 2025, Alessandro Lerda focused on improving the reliability of RTMP streaming pipelines in the ossrs/ffmpeg-webrtc repository. He addressed a critical bug in FFmpeg’s FLV muxer by refining how MP3 tracks with IDs greater than zero are handled, specifically by prepending the required sequence start to the track data. This change resolved an unreachable sequence-start logic issue, enhancing the startup reliability of MP3-in-FLV outputs and ensuring better compatibility with enhanced RTMP. Working primarily in C and C++, Alessandro applied his expertise in AV encoding and FLV muxing to deliver a targeted, maintainable fix that improved streaming resilience.
