Description Lauro Moura 2020-07-06 20:52:03 PDT 
The imported expected file has FAIL/NOTRUN entries for the Mac port (it does not expect to run webm) and results in two FAIL entries for GTK/WPE (they run the webm case).

* Running the video (LayoutTests/imported/w3c/web-platform-tests/media/400x300-red-resize-200x150-green.mp4 or webm) inside GTK MiniBrowser:

Expected behavior:

* Starts with red 400x300
* Switches to green 200x150

Current behavior:

* Starts with both Red and Green rectangles stuck to 400x300 to the end.
* After clicking to play again, the video starts with red 200x150
* Switches to green 400x300
* Sliding back to the red portion shrinks the dimensions again.

Given the error message in the expected file, looks like the first issue (not changing sizes) is also happening on Mac.
