Serving mp4 video to iPad

问题:

I want to serve a mp4 video in a HTML document but it doesn't play on the live server. Locally it works.

Even using only the file without any HTML it does play when I use my local Apache. On the webserver the iPad says "Movie could not be played"

The header for the file is "video/mp4" on both Servers.

What could be the problem here?

Regards

UPDATE:

Header local Apache:

Accept-Ranges    bytes Cache-Control    max-age=86400 Connection    Keep-Alive Content-Length    8993646 Content-Type    video/mp4 Date    Thu, 23 Feb 2012 14:40:58 GMT Etag    "733258-893b6e-36d96c80" Keep-Alive    timeout=15, max=100 Last-Modified    Thu, 23 Feb 2012 10:36:18 GMT

Header live server:

Cache-Control    max-age=86400 Connection    Keep-Alive Content-Length    8993670 Content-Type    video/mp4 Date    Thu, 23 Feb 2012 14:40:40 GMT Keep-Alive    timeout=15, max=100 Server    Apache X-Mod-H264-Streaming    version=2.0

What's also weird is that the Content-Length differs from local to live...

回答1:

Check what the live server is sending out for a mime header v.s. what your local one is. The live server may be sending application/octet-stream (or some other default type) instead of video/mp4. Browsers go by the supplied mime-type in the response headers for the most part, not the served up file extension.

Solution is a wrong Conten-Length header from the live-server. After fixing this problem it worked.

Collegue fixed server settings, so I don't know excactly what he did. Just that the lenght is now the same as on my local machine

If you are using the HTML5 along with a mp4 file. There should be no problems playing the file on your iPad.. the only thing left is to make sure the link is not broken and add this part to make further testing :

<video width="320" height="240" controls="controls">
  <source src="movie.mp4" type="video/mp4" />
  Your browser does not support the video tag. //add this line
</video>

The web server serving the media files should also support 'Accept-Ranges' header. This is mentioned in another stackoverflow question which has a link to apple documentation.
