Description

HawkTracer is lightweight and low-overhead profiler that allows to define custom trace events and provides infrastructure to create post-run and live data analyzers. In this talk, I'd like to demonstrate how can GStreamer applications be profiled and tuned in real time using HawkTracer, GStreamer Tracing subsystem and gst-debugger. I'll explain base concepts of HawkTracer, how to extend the profiler and how to integrate it to existing applications and GStreamer plugins(e.g. gst-shark tracing plugins) to get live profiling data.

Marcin is a software development engineer at Amazon. He spends his free time on contributing to several open source projects. For a few years he's been also a member of GNOME Foundation, where he maintains gstreamermm library and gst-debugger application, and contributes to a few other (mostly C++ related) projects.

Marcin's started using GStreamer framework couple of years ago in his previous job, where he was responsible for delivering video library for UAV system.
