PROFILE
Steven Liu
LQ contributed to the ossrs/ffmpeg-webrtc and FFmpeg/FFmpeg repositories, focusing on media workflow reliability and security. Over three months, LQ built new HLS fMP4 encoding test coverage and enhanced build systems to streamline CI integration, using C and Makefile to automate validation for fragmented MP4 segments. LQ also improved protocol security by enforcing HTTP URL validation in the WHIP signaling path and cleaned up redundant code for maintainability. Addressing stability in DASH streaming, LQ fixed a potential heap overflow in the DASH Demuxer by validating and clamping MPD XML values, demonstrating depth in software debugging and video processing.

Jan 1, 2026January 2026: FFmpeg/FFmpeg—Contributed a high-impact stability fix to the DASH Demuxer by validating MPD XML values, preventing potential heap overflow. Negative values for duration, timescale, and startNumber are now clamped to zero after parsing, reducing crash risk and improving robustness for DASH streaming.
