Worked across FFmpeg/FFmpeg, ossrs/ffmpeg-webrtc, Esri/harfbuzz, and CocoaPods/Specs to deliver targeted improvements in multimedia processing, build system reliability, and dependency management. Developed and integrated features such as VideoToolbox HEVC 4:2:2 10-bit support and MDK dependency upgrades, while resolving complex bugs including Android camera linesize alignment and Direct3D11 linker errors. Applied C and C++ expertise to enhance cross-platform compatibility, using shell scripting and configuration management to automate build probes and stabilize CI pipelines. Addressed symbol resolution and conditional compilation issues, ensuring robust releases and maintainable codebases. Demonstrated depth in embedded systems, graphics programming, and multimedia frameworks.
May 2026 monthly summary for ossrs/ffmpeg-webrtc: Focused on stabilizing the Direct3D11 video path and ensuring reliable builds for Windows targets. Completed a critical linker fix to enable continued development and release workflows for the FFmpeg-WebRTC integration.

June 2025 monthly summary for ossrs/ffmpeg-webrtc: Implemented a robust fix for Android camera device linesize alignment by setting image linesize alignment to 1, replacing the previous 32-byte assumption. This change enhances cross-device compatibility and stabilizes camera input across Android devices, addressing issues observed on devices without 32-byte aligned linesizes (notably Redmi K60). The fix reduces risk of frame misalignment in the avdevice/android_camera module and improves reliability for WebRTC video capture across the device ecosystem.
