Description

There are a lot of tools available to simplify debugging GStreamer applications at runtime. Unfortunately, the situation is quite different, once an application crashes. While gdb can be used to access all the data structures, interpreting the data can be difficult and time consuming. This talk shows how the gdb Python API to simplify debugging GStreamer applications. It will show how Python can be used to determine the overall state of the pipeline and display the GStreamer object and related data structures in a more readable format. Michael Olbrich is an open-source developer with a focus on platform integration on embedded Linux. He works as a full-time Linux developer for Pengutronix. His job is to provide a smooth Linux experience on embedded devices from init systems to graphics and multimedia frameworks. He is the main maintainer for PTXdist, an embedded Linux distribution.
