RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Jonas Ådahl 2019-01-09 07:56:07 UTC 
This is needed for cursor sprite side channelling in screen casting and remote desktop.
Comment 3 Jonas Ådahl 2019-01-10 07:25:50 UTC 
PipeWire 0.2.5 adds mouse cursor buffer metadata support to streams, meaning the compositor (mutter/gnome-shell) can send cursor state without also sending screen content.

https://bugzilla.redhat.com/show_bug.cgi?id=1659118 partially needs this to have the VNC server make use of it, and https://bugzilla.redhat.com/show_bug.cgi?id=1658971 backports the feature to mutter.
Comment 4 Wim Taymans 2019-01-10 10:18:43 UTC 
The current version in 8.0 is 0.2.4, the rebase mostly fixes some compilation bugs, small leaks, a permission fix for flatpak and a crasher.

The cursor metadata does not actually add code, just definitions of structures. There is code added in the example
applications.

0.2.5 has been in Fedora 29/rawhide for a little while now.

I would rate this rebase as very low risk.
Comment 5 Tomas Popela 2019-01-10 13:29:53 UTC 
Please don't forget to backport https://github.com/PipeWire/pipewire/pull/119 otherwise the Firefox and probably others couldn't be build.
Comment 8 Tomas Pelka 2019-01-18 10:20:01 UTC 
Seems to work fine with remote-desktop. Lets wait for testing with remote-desktop over WebRTC and verify if no issues occur.
