QWebKit and Video Cross Platform



  • Hi there,

    i was just developing a project with QWebKit, it needs the html 5 video tag.

    I was developing on Linux and it worked (although i never actually played a video, but the video player controls show up).

    Now compiling first time on Windows (Qt 4.8/QtCreator 2.4.1), there is no support for the video tag... I thought QT was cross platform.

    Is there a way to get the video tag on Windows to run?

    Anyone tried it on mac yet?



  • Check which version of the Web Kit are you using on Windows. According to the official announcement I think that the video tag may be working on "web kit version 2.2":http://trac.webkit.org/wiki/QtWebKitFeatures22



  • Hm, this site says QtWebKit 2.2 is part of Qt 4.8, which i have installed. Does Qt deliver its own WebKit or does it use some system wide installation (which i don't remind installing).

    I made a quick Google research and it seems that other people are experiencing the same issues with video like you but I haven't seen a solution yet :( :
    "QtWebKit 2.2 (from Qt 4.8 RC1) supports less than QtWebKit 2.0.2 (from Qt 4.7.4), test on html5test.com":http://developer.qt.nokia.com/forums/viewthread/11865

  • Did anything change in regards to this? I tried html5 video tag by creating new html5 application with default html page that I modified by adding video tag. It works on Mac but not on Windows. Anyone? Any workarounds for Windows?

        Your browser does not support the video tag.

  • I've written a blog post about how I've solved this issue for our project. It involves building Qt + qt-mobility, and also a bug fix in qt-mobility. See http://blog.enthought.com/open-source/fun-with-qtwebkit-html5-video/

    Great, thank you for sharing the solution. Why don't you create a brief article at "Qt Project's wiki":http://qt-project.org/wiki/ based on your blog post?



  • Hat down, Robin. So much work around it ... it should be really simple.
