            Bug ID: 228825
           Summary: [MSE][GStreamer] Update tracks synchronously
           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

A mistake introduced with the WebKitMediaSrc v2 patch made the call to
updateTracks() in MediaPlayerPrivateGStreamer asynchronous.

This introduced a subtle race condition in which the "resize" event
may be handled before updateTracks() is called, therefore m_hasVideo
has not yet been set to true, and querying the video size from the
"resize" event handler returns 0x0.

This fixes a timeout flake in media/media-source/media-source-resize.html.
