    Question Playing mplayer inside QWidget

    void VistaMedia:: playMplayer()
    { QWidget *player;
    player =new QWidget(0);
    mp=new QProcess(0);
    player ->setGeometry(0,0,500,400);
    QString program = "mplayer";
    QStringList argu;
    argu<< "-fs" <<"-cache"<<"45231"<< "-slave" << "-wid"<<QString ::number(player->winId()) <<"-playlist"<<"playlist.txt";
    mp->start(program,argu);
    player->show();
    }
    Above code is for Windows platform, its showing error on compilation that: "call of overloaded 'number(HWND_*)' is ambiguous"
    am i writing the arguments in wrong order or its a problem related to platform?

    winId() does not return a number on windows, but a pointer (handle) to the window.

    Are you sure it is supported on Windows at all?

    Linux is different than Windows. MPlayer uses XEmbed in Linux and there you can pass a window id which is an integer. On Windows you have pointers to the window structure and those pointers are only relevant inside one process. So it would be wise to read MPlayer's docs to find out if what you want is possible using the method you are trying. Maybe on Windows there is some other mechanism embedded into MPlayer to obtain the same effect.

    Why do you need a Qt written player? Can't you embed Windows Media Player using ActiveX or Phonon (Qt4.4+ only)?

    Dear Ashish!
    You can run MPlayer inside Qt Widget.
    See the M-Player windows documentation.
    I have done it previously.

    You should depict MPlayer manual carefully.
    There is a solution to play MPlayer in Qt Widget.
    I am working on another project that is not Qt Specific thats why the reason I cann't put code to you.
    But Sure, It is possible to run MPlayer on Qt Widget in Windows.
    This is a tricky one work.
    with regards!

    hello drake1983...........
    its so simple yo play mplayer inside widget.........
    just use -wid option of mplayer and provide window id of your QWidget.
    and use -vo option with direct:noaccel .............................

    Then ,how do we get this winID number???

    using casting (int)

    Qt Code:
    1. Qstring winNuber= QString ::number((int) (player->winId()) )
    2. arguments << "-slave" << "-wid" << winNuber << "-vo" << "directx:noaccel" << "-fs" << file ;
    3. m_pProcessVideo->start("C:\\Program Files\\SMPlayer\\mplayer\\mplayer.exe",arguments);
    To copy to clipboard, switch view to plain text mode 

    this works but NOT into the intended window (it uses the full computer screen)

    I think you have to use the native API to convert the handle to the id of the window that is to be passed to mplayer.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
