reading the docs does help sometimes: desktop-screenshot

an idea:

use screenshot to take a number of pictures every 0.5sec or less

then use
Qprocess with mencoder to transform the images into an .avi file

QProcess *mencodeProcess = new QProcess(this);
	mencodeProcess->setWorkingDirectory("C:/JPG");
	QStringList arg;
	QString program = "C:/JPG/mencoder";
 
	arg << "mf://*.jpg" << "-mf" << "w=800:h=600:fps=25:type=jpg" << "-ovc"
			<< "lavc" << "-lavcopts" << "vcodec=mpeg4" << "-oac" << "copy"
			<< "-o" << "a.avi";//tested worked fine
 
 
	mencodeProcess->start(program, arg);
	QString msg;
	if (!mencodeProcess->waitForFinished(1000))
		msg = "Mencoder failed:" + mencodeProcess->errorString();
	else
		msg = "Mencoder output:" + mencodeProcess->readAll();
	qDebug() << msg;

QProcess *mencodeProcess = new QProcess(this);
	mencodeProcess->setWorkingDirectory("C:/JPG");
	QStringList arg;
	QString program = "C:/JPG/mencoder";
	
	arg << "mf://*.jpg" << "-mf" << "w=800:h=600:fps=25:type=jpg" << "-ovc"
			<< "lavc" << "-lavcopts" << "vcodec=mpeg4" << "-oac" << "copy"
			<< "-o" << "a.avi";//tested worked fine

	
	mencodeProcess->start(program, arg);
	QString msg;
	if (!mencodeProcess->waitForFinished(1000))
		msg = "Mencoder failed:" + mencodeProcess->errorString();
	else
		msg = "Mencoder output:" + mencodeProcess->readAll();
	qDebug() << msg;

To copy to clipboard, switch view to plain text mode 

I use this little code before to transform a sequence of jpg to an video .avi

so thank you...
mencoder works...

its work but i have another problem now.

i couldn't capture screen with mouse, is there any way?

Or can i draw a mouse arrow at event.x() and event.y() position on captured QPixmap?

can i record screen realtime?

for example i grab screen as a Pixmap or image and add to created avi file it.

create avi file "x"?

while()
{
grabWindow
add avi file
}

like this
