            Bug ID: 244727
           Summary: [GStreamer] WebKitGLVideoSink fails to acquire GL
                    context in LayoutTests
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aboya at igalia.com

While debugging https://github.com/WebKit/WebKit/pull/3802#issuecomment-1232898953 I found out that video elements don't render any image inside LayoutTests.

This is particularly problematic for any tests relying on visual output, such as reftests.

This is easily reproduced with compositing/video/video-border-radius-clipping.html, which should output a single big green frame -- and does so in the minibrowser -- but appears white when ran in the test runner, for instance, in this EWS results: https://ews-build.s3-us-west-2.amazonaws.com/GTK-WK2-Tests-EWS/dbb1766c-24083/results.html

Passing --wrapper='env GST_DEBUG=webkit*:DEBUG' to run-webkit-tests shows the likely culprit of this, a failure to get a GL context:

0:00:03.530073170    56       0x7f6ac0 WARN       webkitmediaplayer PlatformDisplayGStreamer.cpp:115:tryEnsureGstGLContext: Failed to fill in GStreamer context: could not retrieve fbconfig from its ID 0x42. Wrong Display or Screen?
