PROFILE
Emma Worley
Contributed to the ossrs/ffmpeg-webrtc repository by developing and optimizing core video encoding features in C, with a focus on codec development and performance. Introduced a generic robin hood hash table and migrated the DXT1 encoder to leverage this data structure, improving encoding speed and maintainability. Enhanced interoperability with Resolume by implementing 16-byte texture padding and refining packet consistency. Addressed cross-architecture reliability by standardizing hashtable interactions and ensuring endianness consistency in DXT1 compression, reducing platform-specific artifacts. Demonstrated expertise in low-level programming, algorithm implementation, and FFmpeg internals, delivering stable, portable encoding pipelines and supporting future maintainability for contributors.

Jun 1, 2025June 2025 - ossrs/ffmpeg-webrtc: Delivered a critical DXT1 compression fix to improve cross-architecture reliability in the FFmpeg WebRTC path. Implemented endianness-consistent logic by standardizing hashtable interactions and using direct texture buffer pointers for all hashtable operations, significantly reducing big-endian vs little-endian discrepancies in dxv_compress_dxt1. This work enhances encoding stability and frame integrity across platforms, lowering post-release hotfix risk and supporting higher-quality WebRTC streams.
