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.
