Description Michael Catanzaro 2017-09-12 13:15:55 PDT

Since enabling fatal-criticals for layout tests, several media stream tests are crashing in MediaPlayerPrivateGStreamerOwr::trackEnded with the following error:

g_object_get: assertion 'G_IS_OBJECT (object)' failed

Updating GTK expectations accordingly. Affected tests:

fast/mediastream/apply-constraints-audio.html
fast/mediastream/MediaStream-video-element-video-tracks-disabled.html
webrtc/video-replace-track.html

Also fast/mediastream/argument-types.html. Updating expectations accordingly.

The following also seem to be affected by this.

  webrtc/negotiatedneeded-event-addStream.html [ Crash ]
  webrtc/video-getParameters.html [ Crash ]
