Worked on device firmware and video encoding software, delivering targeted improvements across two open-source repositories. For namiltd/openwrt, addressed boot instability and user interface gaps by correcting RTL8261N reset timing, adding a missing WLAN toggle button via device tree updates, and aligning reported memory size with hardware specifications. This involved C programming, device tree (DTS) modifications, and embedded systems expertise to ensure reliable boot and accurate hardware reporting. In ossrs/ffmpeg-webrtc, stabilized NVENC encoding by refining capability checks in C, preventing false negatives for H.264 High10 profiles on non-MVHEVC hardware, thereby broadening hardware compatibility and reducing encoding-related support issues.
April 2026 monthly summary for ossrs/ffmpeg-webrtc: Focused on stabilizing NVENC encoding capability checks to improve compatibility and encoding flexibility. Implemented a targeted fix to gate MVHEVC capability checks on codec_id, preventing incorrect rejection of H.264 High10 encodes on hardware without MVHEVC support, reducing false negatives and enabling broader hardware support.

March 2026 monthly summary for namiltd/openwrt: Delivered critical stability and usability improvements for BE450 on MT7988/RTL8261N. Key changes include a boot stability fix by correcting RTL8261N reset timing (SMI-ready time adjusted to 221ms), addition of a missing WLAN toggle button (GPIO 34) in the device tree to restore user control, and correction of the memory size reporting from 1 GB to 512 MB to match hardware specifications. Implemented in a single patch (commit f2699cce13fdfb7fac57aad4a59bcd0c63b77014). Overall impact: more reliable boot, functional WLAN controls, and accurate hardware reporting. Technologies/skills demonstrated: OpenWrt kernel/DT patching, MT7988 pinctrl and GPIO/pinctrl wiring, MDIO timing adjustments, and robust hardware-software alignment between DTS and actual hardware. Business value: reduces field issues, improves user experience, and lowers support overhead through deterministic boot behavior and correct device reporting.
