During January 2025, Alessandro worked on the ossrs/ffmpeg-webrtc repository, focusing on improving the reliability of RTMP streaming pipelines. He addressed a critical issue in the FFmpeg FLV muxer by fixing MP3 track handling for tracks with ID greater than zero. Using C and C++, Alessandro modified the avformat/flvenc component to prepend the required sequence start to MP3 track data, resolving an unreachable sequence-start logic bug. This change enhanced the compatibility and resilience of MP3-in-FLV outputs, particularly for edge-case streams, and improved the maintainability of the codebase. His work demonstrated depth in AV encoding and FLV muxing.
