how to change DirectShow backend to Phonon-VLC backend in Windows



  • Hi,

    I'm trying to use phonon-vlc backend instead of directshow backend for phonon to play video on Windows 7 (with VS 2008).
    I did some search but I cannot find a detailed way to do this.
    I know the directshow dlls are in the directory %QTDIR%\plugins\phonon_backend, and I also found the phonon-vlc source from "KDE":https://projects.kde.org/projects/kdesupport/phonon/phonon-vlc/repository, but I don't know how to use it.

    Could you please give me some guide on this? Especially how to replace the dll files and how to tell the system to switch the backend?
    Thanks in advance.



  • I've downloaded Jean-Baptiste Kempf's phonon-vlc package from http://people.videolan.org/~jb/phonon/.
    I tried to put the following dlls in my program directory or Qt phonon_backend directory, but both failed.
    ..\libphonon.dll
    ..\libphononexperimental.dll
    ..\libvlccore.dll
    ..\libvlc.dll
    ..\phonon_backend\phonon_vlc.dll
    ..\plugins..

    Any help please?



  • Do you already know whats going on with this phonon backend stuff. I have actually the same problem...

    Would be nice to hear something from you...

    Thanks and bye

  • As you see no people here can help us on this. So I give up using VLC.



  • Directshow backend is built in a way that it cannot be reincarnated for a different platform. And phonon vlc backend does not allow the switch. The vlc backend is not yet updated to carry these changes, and that’s the reason it can’t generate the required files for the switch.



  • Thanks for replying. This is very useful information and I wish everyone else stuck in this problem won't waste their time ant more. :P
