Hi All,
Please find below a brief summary of the progress Collabora have made last week on Pipewire and Weston/Wayland.
PipeWire
George:
- Updated AGL documentation on PipeWire for icefish &
halibut:
https://jira.automotivelinux.org/browse/SPEC-3254
- Re-worked PipeWire's interfaces for exporting the session
graph:
https://gitlab.freedesktop.org/pipewire/pipewire/-/merge_requests/246
- Implemented exporting of endpoint streams in WirePlumber
Julian:
- Started helping George with the new session management API:
- Implemented wireplumber spa pod API for easy spa pod
bindings
- Implemented wireplumber spa pod builder and spa pod parser
APIs
- Implemented generic wireplumber iterator interface
Weston / Wayland
Marius:
- ozone/chromium and WAM
- added missing set_app_id request for xdg toplevel windows.
Only set_tile was present in the XDG-Shell implementation and
without it we can't figure out the app ids.
- once set_app_id was in place, added missing activation part
of (xdg) surfaces
- ozone/chromium has now all the functionality in place to set
surfaces roles and activate surfaces/windows. For WAM, I've added
front-end code to allow the ability to set-up surfaces roles and
activate apps using the command line. Updated Jira task with
build/usage explanations and described a more efficient solution
which should be implemented along side a mock-up application based
on html5-homescreen. Igalia should have now all the necessary bits
to continue the WAM work and the html5-homescreen one.
- would like to start upstreaming/integrating the agl-shell
work into Igalia's ozone/chromium version, but I need some
feed-back first from Igalia to see how those look like to them +
polish the series a bit (this is a bigger discussion but the gist
of it is that for activating application we need an output, output
which currently is ignored in the front-end side of WAM but passed
a the first output available in the ozone/chromium part -- this
should be somehow relayed from WAM, like we do wit qtwyland or
least have some work-around if that is not entirely
available).
- agl-compositor: While testing the activation part in
ozone/chromium revelead an issue with the
default-activation part of surfaces in the compositor. Posted a MR
fix for it.
- H3 R-CAR validation: homescreen and agl-compositor start up
correctly, looking into
activation part (seems that the application names have chagned
from application@version to
just application, so I need to modify that in my homescreen
version).
Kind regards,
Nick
