media/video-source-media.html is failing on the bots with the following diff:
@@ -1,4 +1,4 @@
-EXPECTED (relativeURL(video.currentSrc) == 'content/test.mp4') OK
+EXPECTED (relativeURL(video.currentSrc) == 'content/test.mp4'), OBSERVED '' FAIL
END OF TEST
It passes reliably on my machine. Could it be that we are missing some package on the server? The video that is being loaded is H.264.
