mp4 videos won't play on ipad / iphone.

I'm trying to see videos on this site, but they won't work neither on the iphone nor ipad. the url is:

If i download those files (mp4 - h.264) to the ipad/iphone, they play well. i guess there is something wrong with the html code.

Any help please?

Thanks a lot.

    Even the Safari web browser is using the Flowplayer fallback player.
    This tells me there is an issue with the VideoJS set-up.
    So in effect there is no HTML5 player for the iDumb devices right now.

    There is an issue with double slashes (i.e. //) in all your URLs.
    My guess is that this is affecting the operation of VideoJS.
    . . . and all the other URLs too.

    Check the set-up of your content management system to eliminate the double slashes.
    Then once that is fixed, if it still does not work check your VideoJS set-up again.
    Safari should be using the HTML5 player if VideoJS is set-up properly and working.

    p.s. It is better to not use spaces in your media file names (or your directory names).
    This has a tendency to confuse the regex's in players.
    And makes a mess of the file name when your users save the file.

    Thanks a lot for your prompt reply. I'll forward this to the developer. I hope he'll solve this issue.

    Thanks again.

    Just downloaded and installed video-js today and it doesn't work on my iphone 4 either but works in safari on my mac. The video is an mp4 h.264 mencoder which was converted from a .mov to a .mp4 using ffmpegX.

    Check out this post and make sure how you're encoding will work on the iPhone.

    I am trying to play h.264 encoded .mp4's and have the same problem. If I use code different than yours they play fine on both iPhone and iPad devices. Help? Thanks!

    Check out the link above and make sure the way you're encoding the videos matches the ipad requirements.

    Thanks for the quick reply again! The video being presented as an .mp4
    is h.264 codec out of Squeeze. When I put the .mp4 in a video tag it
    plays just fine on iPhone and iPad.

    Just a note, Safari on Windows has the exact same behavior as Safari on
    the iPad. The iPhone just shows a black square where the video should
    be, nothing else.

    I've checked all the details of the format, according to this url, thanks Steve Heffernan. The only difference is the fps rate, which is at 25 fps instead of 30. So, i've tried to change this but it doesn't help.

    Thanks Lou Swing for your prompt reply. Could you please explain how to set this video tag, which as i understand would solve this issue?

    Thanks a lot.

    The video tag is simply a manner to play an .mp4 on Apple devices or Safari ONLY. The tag is the following, it is not used for the javascript code we are discussing here. Put that in the body of a page with your file name...

    <video id="myVideo" poster="" width="1280" height="720"
    controls="controls" src="kara.mp4"></video>

    Do i have to tag all my video files that way? because there are lots of files, and i add more files every week :)

    Also, could you please show me an example of this video tag? Is it something like:

    Thanks Lou.

    That video tag is only for Apple stuff basically if that's all you care about? The tags don't show on the posts here, and it super easy even if you're adding files every day. Just look up html5 video tag.....

    Hi again Lou,

    Looks easy. My problem is that i'm the one who uploads the movie files to the site. However, someone else does the code part (html, java,...). So, i don't have access to it.
    Besides, this is quite a pain to do for each file, especially when i got several hundreds already :)
    I'm sure there should be another way to solve this, isn't it?

    Thanks again, Lou.

    Good news, I went back to the original download files and got it working! I was having trouble using the code from scratch. I used your included demo.html file, modified the file names, and perfection, thanks!

    Sorry Lou, but you lost me.

    Please explain yourself, especially how did you got it work.
    Please bare in mind that i've told at first place that playing those same mp4 files from the iphone/ipad work fine, i just can't have them played from this site.

    Thanks a lot.

    I think my last post covered it. Download the video.js files from their site, it's a folder once you get it downloaded. Test it, the demo.html file should play all their videos just fine. Replace the links to their videos with yours, should work fine if your files and file paths are correct, hope that helps...

    Hi Lou,

    If i understand well, you succeeded with my video files (from this site or with the demo site files? Because, the demo site works fine for me. I'm trying to find out what's wrong with my site.
    If you succeeded with my files, using the demo code, then please explain how to solve the issue. I didn't fully understand you, sorry.

    Thanks again.

    The files from the videojs site. If you can get the videojs code, downoaded to your machine and working, then you should be able to implement it into your site. Download the videojs code and work with it, best I can advise, good luck.

    Hi Lou,

    Now you're talking. I'll have to catch my web designer and have him check this.

    Thanks a lot, especially for your patience :)
