Description

In this talk I will present few simple ideas (and tools) for time profiling and data flow inspection between particular elements in GStreamer pipelines. I will underline few aspects that makes common profiling tools usage less effective for GStreamer-based applications and propose few tweaks for GStreamer to make tracing easier.

Kyrylo Polezhaiev is a software engineer and former video game developer, and has an MSc in Systems Engineering. He assembled radio receiver at age eleven, and created a video game (using GStreamer) with 200k+ downloads when he was 21. Kyrylo lives in Kharkiv, Ukraine.
