Playing mplayer inside QWidget

[sinha.ashish]

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.

[sinha.ashish]

ok, but then how to pass it in the mplayer argument?

[wysota]

Are you sure it is supported on Windows at all?

[sinha.ashish]

i am not dead sure,but i did used the same for linux platform with qt 4.3.1, and it worked fine.Now i am using qt4.3.3 on windows.
i don't know its a qt related problem or platform related.
but i just want to play mplayer in a widget...
so help me to get this in any other way...!!

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.

[sinha.ashish]

ok, i am trying...

[sinha.ashish]

i searched for source code of mplayer written in qt got QXMP but it is for linux, and it used QX11EmbedContainer which is not in Qt of windows platform,do anybody know any player written in Qt for windows...???????

[wysota]

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

becoz i didn't know about this , now i will see....

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

[wysota]

I have done it previously.

On Windows?

Dear Ashish!

I know that, but that is not working for windows...

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!

[sinha.ashish]

Ok sir!
i do the same...
thanks a lot for ur time to suggest me...

Hello all!!!!!

the problem i have gone through is solved and it is possible to embed mplayer inside QWidget ,i have done this......

[drake1983]

How did you solve the problem ?

[MrShahi]

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 .............................

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

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

using casting (int)

Qstring winNuber= QString ::number((int) (player->winId()) ) 
 arguments << "-slave" << "-wid" << winNuber << "-vo" << "directx:noaccel" << "-fs" << file ;
m_pProcessVideo->start("C:\\Program Files\\SMPlayer\\mplayer\\mplayer.exe",arguments);

Qstring winNuber= QString ::number((int) (player->winId()) ) 
 arguments << "-slave" << "-wid" << winNuber << "-vo" << "directx:noaccel" << "-fs" << file ;
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)

[wysota]

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.
