Worked on the FFmpeg/FFmpeg repository to address a critical bug affecting video frame decimation quality. Focused on refining the logic that determines when frames are dropped, the developer improved the keep option by introducing similarity checks during the keep period, ensuring frames are only dropped if they differ from the reference frame. This approach stabilized reference frame handling and prevented both unnecessary frame drops and reference drift across scenes. Utilizing C programming and algorithm optimization skills, the work enhanced output video quality and reliability in video processing pipelines. All changes were committed following code review, reflecting a methodical and detail-oriented engineering process.
