P3: Somewhat important Description
Hello,
I'm trying to compile QtWebEngine with PipeWire support for Arch Linux package in order to enable screen sharing under Wayland as per [1] and [2], however I can't figure out if this is possible to achieve today - any help is highly appreciated!
Here's what I found so far:
I noticed in src/3rdparty/chromium/third_party/webrtc/webrtc.gni the following snippet:
# Set this to use PipeWire on the Wayland display server. # By default it's only enabled on desktop Linux (excludes ChromeOS) and # only when using the sysroot as PipeWire is not available in older and # supported Ubuntu and Debian distributions. rtc_use_pipewire = is_desktop_linux && use_sysroot
The Arch Linux packages for Chromium [3] (which is compiled with PipeWire support) and QtWebEngine both build with `use_sysroot=false`, I assume this is correct and should not be changed, so I am looking for a way to override `rtc_use_pipewire` parameter.
As far as I understood there is no way to just pass gn variables directly when compiling QtWebEngine, the only way is to add a new Qt feature (say `webengine-webrtc-pipewire`) and pass it to `qmake` like so:
$ qmake . -- -webengine-webrtc-pipewire ...
Is this correct?
If yes, I believe the patch below does the job, but maybe you will want to adapt it before merging.
Did I miss something? Let me know your thoughts!
