Contributed to the mpv-player/mpv repository by delivering targeted improvements in video streaming performance, arithmetic safety, and input validation over a three-month period. Enhanced YouTube streaming by introducing a request_size AVOption in Lua, leveraging FFmpeg’s http_chunk_size to accelerate video loading and cache population. Developed cross-platform safe arithmetic macros in C, including overflow prevention for HLS bitrate calculations, ensuring stability and portability. Addressed overlay command input validation by replacing multiplication-based range checks with division to prevent integer overflow, reducing crash risk from malformed inputs. Demonstrated a methodical approach to systems programming, compiler optimization, and macro programming to improve reliability and performance.
July 2026 monthly work summary for mpv-player/mpv: Delivered a robust safety improvement for overlay command input validation by replacing a risky multiplication-based range check with a division-based approach to prevent integer overflow. This change strengthens stability for user-facing overlays and reduces risk of crash or exploit due to malformed inputs. Implemented as part of the fix for overlay input handling and closes issue #18128.

February 2026 performance-focused update for mpv: Implemented a streaming performance enhancement by introducing a new request_size AVOption and leveraging FFmpeg's http_chunk_size to accelerate YouTube video loading and cache population. Changes were made in the ytdl_hook Lua integration and include a safe fallback if the option is unavailable to preserve compatibility across builds. This work addresses streaming throttling-related pain points and aligns with mpv's streaming optimization roadmap. The patch was a collaborative effort (Co-authored-by: Nicolas F) and references upstream FFmpeg guidance.
