Worked on the pion/mediadevices repository to address a critical issue in the VPX encoder’s frame timestamp handling, focusing on improving streaming reliability. The solution involved replacing nanosecond-based tracking with Go’s time.Time objects and refining duration calculations using Sub and Microseconds, which reduced timestamp drift and prevented frame reordering. To ensure ongoing correctness, a regression test was introduced to validate monotonic frame timestamps, enhancing the robustness of the encoding path. This work leveraged Go programming, timestamp handling, and unit testing skills, resulting in more stable media pipelines, fewer latency spikes, and improved continuous integration coverage for the project.
