I can confirm the issue on my late 2009 mac mini with OSX10.9.5
The ftp server that mozregression is using is at under 10kb/s at the moment and I gave up for today

The linked file has an HE-AAC audio track.  There were a lot of OS X decoder changes around 32, so likely a regression from those.  CCing the appropriate people.

Sorry, I meant 35.  We first shipped MP4 support on OS X in 34.

Tested and it works for me. Re-open if this is still an issue.
