The problem is that it is not being displayed in c

    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 & 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.

    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:-

    <!DOCTYPE html>
<html>
<head>
</head>
<body>
<video  controls >
 <source src="sample.mp4" type="video/mp4">
 <track kind="subtitles" src="sample.vtt" label="gcsubs" srclang="eng">
</video>
</body>
</html>

    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

    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

    Also check your version of crome here: html5test

    Encountering the same problem, I solved this by reconverting the file with default mp4 settings in iMovie.

    I too had the same issue. I changed the codec to H264-MPEG-4 AVC and the videos started working in HTML5/Chrome.

    Option selected in converter: H264-MPEG-4 AVC, Codec visible in VLC player: H264-MPEG-4 AVC (part 10) (avc1)

    Hope it helps...
