Bug ID: 222888
Summary: [GStreamer] CaptureDevice monitor used from UIProcess
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Platform
Assignee: webkit-unassigned at lists.webkit.org
Reporter: pnormand at igalia.com
CC: cgarcia at igalia.com
If the webapp starts listening on the devicechange event on the MediaDevice (hello jitsi), a RELEASE_ASSERT is hit, because the UserMediaPermissionRequestManager (WebProcess) sends a BeginMonitoringCaptureDevices message to the UIProcess...
