HTML5 Video not working in IE 11

Question

I have a video archive that I have working in everything except IE 11. I get the error "Error: Unsupported video type or invalid file path" when loaded in IE 11. Below is the HTML I am using.

<video id="movie" width="640" height="400" autobuffer controls preload="auto"> 
                <source src="/media/Archive_Videos/September%202013/September_13_U-RUN.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' />
                <source src="/media/Archive_Videos/September%202013/September_13_U-RUN.webm" type='video/webm; codecs="vp8, vorbis"' />
                <source src="/media/Archive_Videos/September%202013/September_13_U-RUN.ogv" type='video/ogg; codecs="theora, vorbis"' />
                    <object type="application/x-shockwave-flash" data="http://player.longtailvideo.com/player.swf" width="640" height="360">
                        <param name="movie" value="http://player.longtailvideo.com/player.swf" />
                        <param name="allowFullScreen" value="true" />
                        <param name="wmode" value="transparent" />
                        <param name="flashVars" value="controlbar=over&amp;file=SITE%2Fmedia%2FArchive_Videos%2FSeptember%25202013%2FSeptember_13_U-RUN.mp4" />
                        <span title="No video playback capabilities, please download the video below">September 2013 U-RUN</span>
                    </object>
                <p>OOPS! It looks like your browser doesn't support HTML5 videos. You can either install the latest version of your browser or download the video below:
                <br /><a href="SITE.com/media/Archive_Videos/September%202013/September_13_U-RUN.mp4">MP4 format</a> | <a href="SITE.com/media/Archive_Videos/September%202013/September_13_U-RUN.ogv">Ogg format</a> | <a href="SITE.com/media/Archive_Videos/September%202013/September_13_U-RUN.webm">WebM format</a></p>
            </video>

I also have an .htaccess file so it works in Firefox.

AddType audio/ogg oga ogg 
AddType video/ogg ogv

Why isn't it working in IE 11?

Answer 1

What is the resolution of the video? I had a similar problem with IE11 in Win7. The Microsoft H.264 decoder supports only 1920x1088 pixels in Windows 7. See my story: http://lars.st0ne.at/blog/html5+video+in+IE11+-+size+does+matter
