• HTML5 video player doesn't work on iPad/iPhone

  16 avril 2015, par Avrohom Yisroel

  NOTE This turned out to be a simulator problem, not a video encoding problem, see my edit lower down...

  I’m creating a web site for a local college, and they want to be able to add short videos that people can view online. I’ve spent quite a bit of time trying to work out how to get the videos to play on iDevices, but have failed.

  I’m using Video.js (http://www.videojs.com), and have HTML that looks like this...

  <video class="video-js vjs-default-skin" controls="controls" preload="auto" width="640" height="352" poster="/Content/Images/logobg.png" data-setup="{}">
  
    <source src="/Content/Videos/video.m4v" type="video/mp4">
  
    <source src="/Content/Videos/video.webm" type="video/webm">
  
    <p class="vjs-no-js">
  
      To view this video please enable JavaScript, and consider upgrading to a web browser that <a href="http://videojs.com/html5-video-support/" target="_blank">supports HTML5 video</a>
  
    </p>
  
  </source></source></video>

  This works fine on desktop browsers, where it uses the m4v file. However, if I load the page on an iDevice, the video player says "no compatible source was found for this video", which sounds like it doesn’t like either the m4v or the webm file.

  I created the webm file using instructions found at http://daniemon.com/blog/how-to-convert-videos-to-webm-with-ffmpeg/. I tried creating a .mov file using the accepted answer at iPad Doesn’t Render H.264 Video with HTML5, but this gave the same error.

  Anyone any ideas how I can support iDevices ? Please don’t blind me with science, I’m a real newbie with all this video stuff, and need simple instructions !

  Edit The problem I was having was when trying to view the site on a mobile simulator. When I uploaded the site to a real server, and tried it on an iPad, it worked fine. So, if anyone is having a similar problem, first use something like Handbrake to encode the videos, as it seems to do it fine, then make sure you’re testing on a real mobile device, not a simulator !

• lavf : Replace the ASF demuxer

  lavf : Replace the ASF demuxer
  The old one is the result of the reverse engineering and guesswork.
  
  The new one has been written following the now-available specification.
  This work is part of Outreach Program for Women Summer 2014 activities
  
  for the Libav project.
  The fate references had to be changed because the old demuxer truncates
  
  the last frame in some cases, the new one handles it properly.
  
  The seek-test reference is changed because seeking works differently
  
  in the new demuxer. When seeking, the packet is not read from the stream
  
  directly, but it is rather constructed by the demuxer. That is why
  
  position is -1 now in the reference.
