Description

It is about one interesting side of the GObject, that allows us to use in runtime an already registered gstreamer element as a base class, and therefore register a new gstreamer element that would contain certain modifications or interceptions applied to the original one.
In particular this can be interesting because it allows to intercept the behaviour of an element, the code of which we can’t or don’t want to modify.

The technical side of the idea is quite simple, you can find the explanation is a short code example here:
https://github.com/aslobodeniuk/fun/blob/master/gobject-mutogene/examples/gobject-mutation.c

The possible usecases are not that clear, so at the same time we will present that few we can imagine but also let the listeners think about if they can propose more usecases.

The talk could be scheduled as:

Brief introduction into how the GType registration works, and how GStreamer uses it - 10 min

Walk through the code example - 10 min

Speaking about the possible usecases - 5 min

Questions - 5 min

Speaker bio From Fluendo, it have been 6 years I'm working with GStreamer
