Mini talk I did at FOSDEM 2010 in the GNOME dev room.

1. Multimedia in
WebKitGTK+
Past / Present / Future
Philippe Normand, Igalia

2. About WebKit itself
IT IS NOT A BROWSER, it is a framework to build
browsers
Fork of KHTML started by Apple, now with
contributors all over the place.
Shared base, with ports being built from the
same tree, with different build systems.
2 core bricks: WebCore and JavascriptCore
No stable API, no API documentation
Each port provides its own API

3. What is WebKitGTK+?
a WebKit port providing a GTK+ friendly API
A regular GtkWidget which you can add to your
GtkScrolledWindow.
Rendering backend built with Cairo.
Resource loading backend built with libsoup.
Pango for fonts
Keyring for auth storage
GStreamer for audio/video

4. Multimedia in WebKit
3 layers from top to bottom:
DOM: HTMLMediaElement
graphics: cross-platform MediaPlayer bridge
platform-specific MediaPlayerPrivate backend
In the GTK+ port: video painting on a Cairo
surface, buffers retrieved from a custom video
sink.

5. Until September 2009
(past :))
36% Skipped media tests, out of 97 (flaky or
missing features).
Not really useful without controls UI.
Demo from the past

6. Since September 2009
(present!)
Only 23% Skipped media tests (out of 108)!
Simple controls UI (initial patch by Zan
Dobersek)
Trick modes (reverse playback, ffwd playback)
QuickTime ref movies: redirections
Better integration with PulseAudio
data: uris support (upstreamed to gst-plugins-
bad)
on-disk buffering (review in progress)
