the methods in the videoEngine:

void CVideoEngine::InitControlerL(RWsSession& aWs,CWsScreenDevice& aScreenDevice, RWindowBase &aWindow,
const TRect &aScreenRect, const TRect &aClipRect, const TDesC& aFileName)

{
iVideoPlayer=CVideoPlayerUtility::NewL(*this, EMdaPriorityNormal,
EMdaPriorityPreferenceNone, aWs, aScreenDevice, aWindow,
aScreenRect, aClipRect);

iVideoPlayer->OpenFileL(aFileName);

}
The method in the AppUi class to call the above method:

void CVideoClipAppUi:oInitControllerL(const TDesC& aFileName)
{
iEngine->InitControlerL(iAppView->ClientWsSession(),
iAppView->ScreenDevice(), iAppView->ClientWindow(),

Hi,

I assume that the reason why the emulator exits is that your application crashes.

1/ Did you tried to debug it? If no, do that to know on which function the code will stop.

2/ I guess that one of the methods will leave with KErrNotSupported (-5) error, because as I remember playing/recording video is not supported on emulator.

The shutdown may also happen because you execute your application directly. If you start the emulator instead (http://wiki.forum.nokia.com/index.ph...arbide.c%2B%2B), it will not exit, just your application will panic (enable the extended messages: http://wiki.forum.nokia.com/index.ph...ded_panic_code). Then you may get some negative numbers, as Stenlik mentions (http://wiki.forum.nokia.com/index.php/Error_codes).
