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.

This is needed to have the screen sharing working in WebRTC on Wayland. Otherwise users of Bluejeans and other WebRTC clients won't be able to share the screen on Wayland in RHEL 8.

Backport the Firefox version of the upstream WebRTC patch that's adding the PipeWire support. The patch needs to be taken from Fedora package and adapted to the Firefox ESR release in RHEL 8 as Firefox doesn't use the up to date WebRTC code (it uses an older release of it from few years ago).

Patch for adding the PW support

set exception+ per request and review

Note to QA - it can be tested by visiting the https://mozilla.github.io/webrtc-landing/gum_test.html and clicking the "Screen" button.

OK checked Video, Video&Audio, screen and that worked, what did not worked was Application and for Window I was not able to share particular window. So if this is expected I would call this as verified.

Tomas do you know?

That's true Tom. Currently there is only support for screens. The WebRTC implementation is ready for the windows part, but it needs some changes on xdg-desktop-portal and I think mutter, but these are pending.

Thanks Tom!
