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

I believe IE requires the H 264 or MPEG-4 codec  which it seems like you don t specify include  You can always check for browser support by using HTML5Please and Can I use     Both sites usually have very up-to-date information about support  polyfills  and advice on how to take advantage of new technology

In my case Codec ID of mp4 file was the issue  Codec ID  isom  isom iso2 avc1 mp41  was not playing in IE 10 and 11 using video tag  after I converted it to  mp42  mp42 isom avc1   using FFmpeg it started playing in IE as well

It was due to IE Document-mode version too low  Press  F12  and using higher version  My case  above version 9 is OK

I used MP4Box to decode the atom tags in the mp4   MP4Box -v myfile mp4   I also used ffmpeg to convert the mp41 to mp42   After comparing the differences and experimenting  I found that IE11 did not like that my original mp4 had two avC1 atoms inside stsd   After deleting the duplicate avC1 in my original mp41 mp4  IE11 would play the mp4

I know this is old  but here is a additional thing if you still encounter problems with the solution above   Just put in your  lt head gt      lt meta http-equiv  X-UA-Compatible  content  IE edge  gt     It will prevent IE to jump back to IE9 compatibility  thus breaking the video function  Worked for me  so if you still have problems  consider checking this out   Alternatively you can add this in PHP    header  x-ua-compatible  ie edge      Or in a  htaccess file   header set X-UA-Compatible  IE Edge

Although MP4 is supported in Internet explorer it does matter how you encode the file  Make sure you use BASELINE encoding when rendering the video file  This Fixed my issue with IE11

I ve been having similar issues of a video not playing in IE11 on Windows 8 1  What I didn t realize was that I was running an N version of Windows  meaning no media features were installed  After installing the Media Feature Pack for N and KN versions of Windows 8 1 and rebooting my PC it was working fine   As a side-note  the video worked fine in Chrome  Firefox  etc  since those browsers properly fell back to the webm file
