Cameras - especially the ones built out of a sensor connected to an embedded board - have a tendency to be hard to develop and debug. After the initial bringup and getting the core mechanics to work it is often time to look at actual images. Connecting external displays or opening single frames saved to the filesystem quickly becomes a tedious task.

Time to introduce camshark, a tool that makes working on libcamera based cameras easier than ever. Camshark grew from an idea to a tool that is in daily use by many of the core libcamera developers. This talk will give an overview on the underlying concepts and show how camshark can be used for problem analysis and debugging of libcamera based cameras.
