Worked on the obsproject/obs-studio repository to address a critical reliability issue affecting the Linux virtual camera feature when used with older v4l2loopback module versions. Developed and implemented a workaround in C that resets output capabilities and conditionally applies STREAMON and STREAMOFF operations during device open and close, ensuring stable startup behavior across different module versions. This solution improved cross-version compatibility and reduced startup failures for end users in livestream production environments. Demonstrated expertise in Linux kernel modules, device driver development, and the V4L2 API, with a focus on low-level debugging, cross-team collaboration, and commit-based change management.
