Description Simon Fraser (smfr) 2010-02-15 20:46:33 PST 
If the <video> is autoplay, and also has a poster, the video doesn't seem to show reliably. If you resize the window, things show up.

Patch


 22 <video width="480" height="270" type="video/mp4" src="content/test.mp4" poster="content/abe.png" autoplay>

+ <video> doesn't have a 'type' attribute, only <source> does. You should just remove it.


+ Not all ports support MPEG-4, but there are alternate encodings of all of most test movies so instead of hardcoding the src directly in the markup you should include "media-file.js" and set the src in doSetup with 

  video.src = findMediaFile("video", "content/test");


+ We have hardware compositing on Windows, won't it break unless it implements platformLayer()?
