• MP4 Videos on website embed with html5 does not play on iOS

  31 août 2012, par Sidner

  So I have a couple of videos on my website that I shot using the iPhone 4 and then converted to mp4, webm and ogg, so that I can use them with html5. Thing is, the video does not play at all on the 4 iOS devices that I tested and neither on Chrome for Android.

  The Chrome issue could be because some of the mp4 are actually m4v files, but still after encoding with handbrake a video to the iphone 4 presset and in mp4 format, it still does not play.

  What happens, you ask ? Well, it shows the play button crossed out with a diagonal bar, the debug console on Safari does not show any message untill I try to access the video directly. Then it says : QuickTime Movie could not be played.

  What can I do ? I have been trying to encode with ffmpeg, have tried a handful of different solutions, some even found here on stackoverlow, but to no avail. The videos do get shorter, both in display size and MBs, but nothing works to fix the issue at hand.

  I've been trying to get this corrected for a couple of weeks now. Any help and/or suggestions are welcome.

  Thank you.

  By the way, all the videos are on a registred users section of the website, but I have one for debugin on the main page, so feel free to test.
