[webkit-qt] HTML5 video doesn't work on Windows

[Paul Pedriana]

We cannot get HTML5 video to work on Windows. Multiple users have tried 
it and none seem to be able to succeed. I cannot find a reference to 
anybody on the Internet getting this to work, and a bug entry 
(https://bugs.webkit.org/show_bug.cgi?id=39464) which has not been 
updated seems to confirm the theory that QtWebKit doesn't currently 
support HTML 5 video on Windows.

We need to make some decisions about what kind of video we will be using 
in production and need to simply know yay or nay if it works. If not 
then we need to use Flash video instead, which is fine but it's 
something we will be stuck with.

Environment:
     Qt 4.6.2, 4.7.0b1, 4.7.0b2.
     Windows XP, Vista, Windows 7; 32 and 64 bit versions.

Repro steps:

     Make sure Ogg DirectShow plugin is installed (http://xiph.org/dshow/).
     Make sure the h.264 plugin is installed 
(http://www.free-codecs.com/download/FFDShow.htm).
     Run the browser.exe app from Qt 4.7.0b2.
     Navigate to http://chaos.troll.no/~tavestbo/webkit/mediaelement/ 
<http://chaos.troll.no/%7Etavestbo/webkit/mediaelement/> (HTML5 video 
fails everwhere we have tried, not just this page).
     Try to play video (either ogg or h.264). It doesn't work:

     The video file appears to start loading but doesn't play.
     Drag video .ogg file to the browser window in order to play it 
directly. It does work: http://i.imgur.com/eLjzJ.png

This problem happens with video transferred over either http:// or for 
file://.

Thanks.
