H.264 videos not playing in firefox in html 5
I have my player setup to use HTML 5 as primary and it works in all browsers except Firefox. I am currently on 36 but noticed it wasn't working on 35. On older versions it would play with flash but now it is trying to load the video in HTML 5.
I have 2 videos I tried testing using the publish feature on my account and one works and the other doesn't. they are both h.264 AAC encoded the only difference is the aspect ratio and the audio quality from what I can tell.
http://www.level3.com/~/media/videos/en_voice_vd_carriercloud_alianza.mp4 - this one works
http://www.level3.com/~/media/videos/whiteboard_federal_640_360.mp4 - this one doesn't
any ideas on why this is only a problem on one of the two and only in Firefox?
