roc, this started being much more frequent around the 12th - any ideas? :-)

Maybe cpearce does

There were no code changes to content/media between August 28 to (at least) 18 September, so I don't see how anything we did around 12 Sep could affect this.

Cute that this went from being just a tiresome constant uncaught exception to being a timed out after 330 seconds with no output and destroyed the entire test suite's run.

All of these test failures seem to involve two particular video files: * seek.webm * bug516323.indexed.ogv (this video's failures seem about ~5x more common) I confirmed that, when the failing tests receive the loadedmetadata event, the video element's duration is Infinity, not NaN or some other value. MDN says: "If the media data is available but the length is unknown, this value is NaN. If the media is streamed and has no predefined length, the value is Infinity." Why would loadedmetadata intermittently think the video is streamed and has no predefined length? I could understand a (valid) network race condition where loadedmetadata is fired before the video length is known, but wouldn't duration would be NaN, in that case?
