Cannot get vlc activeX control to play video

[lmwork]

I'm trying to develop a simple c++ application and cannot get the vlc activeX control to play video. When I run my program I can see the activeX widget but no video will play. Here is my example program.

int main(int argc, char *argv[])
{
QApplication app(argc, argv);

//MainWindow mainWin;
//mainWin.show();

QAxWidget* mediaPlayer_ = new QAxWidget;
QString source("Videos/Formation Reference-3.mpg");
mediaPlayer_->setControl( "{9BE31822-FDAD-461B-AD51-BE1D1C159921}"); //string is class ID for VLC Media Player
mediaPlayer_->setProperty("mrl", source);
mediaPlayer_->setProperty("autoplay", true);
mediaPlayer_->setProperty("autoloop", true);
mediaPlayer_->setProperty("visible", true);


return app.exec();
}



Any suggestions.

Below are the errors I receive:

Hi,

here are just some ideas, nothing sure:
- You give a QString to mrl, what happen if you give it a legacy null-terminated char*? (well, the QT object maybe handle this directly)
- I can not see where is displayed the ActiveX, isn't it embedded in a visible window? (with commented lines I suppose you already tried it)
- You can try to comment the setProperty("mrl" line and use ".playlist.add()"-equivalent call, later.

I tried your suggestions and got the same results.

I also tried to create an instance of VLCControl and was not successful.

I also tried to used the interface directily with IVLCControl ,C2FA41D0-B113-476e-AC8C-9BD14999C1C1, I was unsuccessful, got message saying class not registered (I registered the axvlc.dll); is it something else I have to do the use IVLCControl?

Do you know where a working example of a c++ application that interfaces with the vlc activeX control, my c++ application is being built in Microsoft Visual C++ .Net 2003; I have vlc version 9.8a

Thanks in advance...
