Worked on the ossrs/ffmpeg-webrtc repository to enhance the FFV1 encoder by increasing the slice limit to 1024, with vertical slices expanded up to 32, allowing for more flexible and efficient encoding of complex video content. Addressed log management by introducing a maxsize_warned flag, ensuring that the maximum packet size warning appears only once, which reduces log clutter during extended encoding sessions. Utilized C and focused on FFmpeg’s avcodec module, applying skills in codec development, video encoding, and error handling. The work improved both encoding performance and user experience, reflecting a targeted approach to performance and maintainability within the codebase.
