After running into the same issue - here're some of my thoughts:

due to Chrome removing support for h264, on some machines, mp4 videos encoded with it will either not work (throwing an Parser error when viewing under Firebug/Network tab - consistent with issue submitted here), or crash the browser, depending upon the encoding settings
it isn't consistent - it entirely depends upon the codecs installed on the computer - while I didn't encounter this issue on my machine, we did have one in the office where the issue occurred (and thus we used this one for testing)
it might to do with Quicktime / divX settings (the machine in question had an older version of Quicktime than my native one - we didn't want to loose our testing pc though, so we didn't update it).

As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:

for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:

if (window.chrome)
    $("[type=video\\\/mp4]").each(function()
    {
        $(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
    });

Unfortunately it's a bad Chrome hack, but hey, at least it works.

This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec

This started out as an attempt to cast video from my pc to a tv  with subtitles  eventually using Chromecast  And I ended up in this  does not play mp4  situation  However I seemed to have proved that Chrome will play  exactly the same  mp4 as long as it isn t wrapped in html 5  So here is what I have constructed  I have made a webpage under localhost and in there is a default htm which contains -   lt  DOCTYPE html gt   lt html gt   lt head gt   lt  head gt   lt body gt   lt video  controls  gt    lt source src  sample mp4  type  video mp4  gt    lt track kind  subtitles  src  sample vtt  label  gcsubs  srclang  eng  gt   lt  video gt   lt  body gt   lt  html gt    the video and subtitle files are stored in the same folder as default htm  I have the very latest version of Chrome  just updated this morning   When I type the appropriate localhost    into my Chrome browser a black square appears with a  GO  arrow and an elapsed time bar  a mute button and an icon which says  CC   If I hit the go arrow  nothing happens  it doesn t change to  pause   the elapsed time doesn t move  and the timer sticks at 0 00  There are no error messages - nothing    note that if I input localhost   to IE11 the video plays      In Chrome if I enter the disc address of sample mp4  i e  C  webstore sample mp4 then Chrome will play the video fine    This last bit is probably a working solution for Chromecast except that I cannot see any subtitles  I really want a solution with working subtitles  I just don t understand what is different in Chrome between the two methods of playing mp4

I was actually running into some strange errors with mp4 s a while ago  What fixed it for me was re-encoding the video using known supported codecs  H 264  amp  MP3    I actually used the VLC player to do so and it worked fine afterward  I converted using the mentioned codecs H 264 MP3  That solved it for me   Maybe the problem is not in the format but in the JavaScript implementation of the play  pause methods  May I suggest visiting the following link where Google developer explains it in a good way   Additionally  you could choose to use the newer webp format  which Chrome supports out of the box  but be careful with other browsers  Check the support for it before implementation  Here s a link that describes the mentioned format   On that note  I ve created a small script that easily converts all standard formats to webp  You can easily configure it to fit your needs  Here s the Github repo of the same projects
