PROFILE

Andrzej Surdej

Andrzej Surdej developed and integrated advanced media and system features across LibertyGlobal/WPEWebKit and rdkcentral/meta-rdk-video, focusing on platform compatibility, observability, and streaming quality. He implemented ftrace-based system tracing in C++ to enhance performance analysis and debugging, and introduced programmatic GStreamer capability checks to improve cross-platform reliability. Andrzej delivered runtime HDR and Dolby Vision streaming support in WebKit, refining codec handling and adapting HDR logic to device capabilities. His work also addressed runtime safety and crash-report accuracy, using CMake and Shell for build system improvements. These contributions demonstrate depth in embedded systems, media pipeline development, and cross-platform integration.

Feb 1, 2025

February 2025 delivered enhanced observability for LibertyGlobal/WPEWebKit by adding ftrace-based WebKit tracing on Linux. Implemented new tracing headers, integrated ftrace into the system tracing mechanism, and enabled trace points to be written in a Perfetto-compatible format to the trace_marker for visualization and debugging on STB devices. These changes enable detailed performance analysis, faster triage, and data-driven optimizations across the WebKit stack.
