Update on what happened in WebKit in the week from August 11 to August 18.
This week we saw updates in WebXR support, better support for changing audio outputs, enabling of GLib API when building the JSCOnly port, improvements to damaging propagation, WPE platform enhancements, and more!
Cross-Port 🐱
Complementing our WebXR efforts, it is now possible to query whether a WebView is in immersive mode and request to leave immersive mode.
Multimedia 🎥
GStreamer-based multimedia support for WebKit, including (but not limited to) playback, capture, WebAudio, WebCodecs, and WebRTC.
Changing audio outputs has been changed to use gst_device_reconfigure_element() instead of relying on knowledge about how different GStreamer sink elements handle the choice of output device. Note that audio output selection support is in development and disabled by default, the ExposeSpeakers, ExposeSpeakersWithoutMicrophone, and PerElementSpeakerSelection features flags may be toggled to test it.
While most systems use PipeWire or PulseAudio these days, some systems may need a fix for the corresponding ALSA and OSS elements, which has been already merged in GStreamer.
JavaScriptCore 🐟
The built-in JavaScript/ECMAScript engine for WebKit, also known as JSC or SquirrelFish.
Support for enabling the GLib API when building the JSCOnly port has been added.
Graphics 🖼️
With the #44192 PR landed, the damage propagation feature is now able to propagate damage from accelerated 2D canvas.
WPE WebKit 📟
Fixed minor bug in WPE's: pressing Esc key inside a dialog closes dialog. See PR #49265.
WPE Platform API 🧩
New, modern platform API that supersedes usage of libwpe and WPE backends.
The WPEPlatform DRM backend can now report available input devices. This is mainly used to support Interaction Media Features queries, which allow web sites to better adapt to the available input devices.
That’s all for this week!
