    Hi there
    I am trying to implement MediaPlayer in my Sitefinity project and it seems that mp4 is widely supported now. Even my opera plays it.

    mp4 should play on ipad and iPhone as well but mine is not working.

    Now http://demos.telerik.com/aspnet-ajax/media-player/examples/overview/defaultcs.aspx does not work for me on iPad either.

    Can anyone check if the demo is running on their iPad, iPhone?

    -------------
    If not I found some stuff on the web. Anyone with some know-ledger?

    - iOs doesn't support all the profiles that h.264 provides. You have to encode your h264 with a baseline profile only in order for it to be playable on iphone/ipad.

    - One important thing to note is that "iDevices" doesn't support all the varieties of mp4. Here is a small list about MPEG-4 and H.264 supported varieties.According to Apple official website, iPad or iPhone 4S is only compatible with H.264 or MPEG-4 video format with the following specifications:

    If it is H.264 video, it should meet: up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
    If it is MPEG-4 video, it should meet: up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;

    But there are some forums saying that in fact, the iPad specifications are these:
    iPad Supported Video FormatH.264 video (up to 720p, 30 frames per second; main profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats)
    MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats.

    The problem on my site was solved by switching the Sitefinity Library to file system.
