Little bit confused at the moment, I have 2 .mp4 files, both with h.264 encoded video.

| #Safari | Video 1 | Video 2 |
| Windows | Failed  | Played  |
|   OSX   | Played  | Played  |

My Code

<video width="550" height="400" controls>
    <source src="test/charlie.mp4" type="video/mp4" /> 
    <source src="test/charlie.ogv" type="video/ogg" /> 
  Nope.
</video>

Video 1

Status: HTTP/1.1 200 OK
Date:   Wed, 27 Jun 2012 09:19:02 GMT

Content-Type:   video/mp4

Video 2

The ffmpeg command I am using for Video 1 is

ffmpeg -y -i input.avi -vcodec libx264 -r 24 -preset medium -crf 20 -bufsize 20M -acodec libfaac -ac 2 -ar 44100 -ab 128k out.mp4

Anyone seen this kind of behaviour before?

What behaviour are you referring to? – bart s
the fact that it plays in osx but not windows (same file, same code, same browser) – Jamie Taylor
Did you catch the error event from the video tag? see here for example stackoverflow.com/questions/2741493/… – bart s
Safari doesn't even load the video so can't trigger the event, but at the same time it doesn't display my "nope" message – Jamie Taylor
So the http headers are not from the failing video. Can you look in windows safari developer tools what requests (and headers) are sent out and update your question with the relevant infomation – bart s

-preset medium looks a bit suspicious. What is that exactly? IIUC H264 depends on [levels](http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Levels] which have varying support amongst devices and browsers.
