During January 2025, work focused on improving the stability of RTMP streaming pipelines in the ossrs/ffmpeg-webrtc repository. The developer addressed a critical issue in FFmpeg’s FLV muxer by fixing MP3 track handling for tracks with ID greater than zero. This involved prepending the required sequence start to MP3 track data, resolving an unreachable sequence-start logic bug that previously affected streaming startup reliability. The solution enhanced compatibility and resilience for MP3-in-FLV outputs, particularly in edge cases. The work was implemented in C and C++, leveraging expertise in AV encoding, FLV muxing, and RTMP protocols to improve maintainability and streaming performance.
