Worked on the pion/mediadevices repository to enhance media pipeline reliability by delivering three core features focused on encoding efficiency and decoding robustness. Developed a BitrateTracker utility in Go to monitor and calculate bitrate over a moving time window, supporting real-time performance monitoring. Introduced dynamic quantization parameter control for VP8 encoding using Cgo and interface design, enabling adaptive bitrate management without sacrificing video quality. Expanded VPX decoding capabilities by implementing Cgo bindings for VP8 and VP9, improving error handling and decoder interface robustness. Emphasized thorough unit testing and error propagation to ensure stability and maintainability across the encoding and decoding stack.
