gettin a movie screencap

[geek@02]

hi
below i'm trying to get a movie screencap. but i get error no 259: "Driver cannot recognize the specified command parameter" error after the capture command returns. what i'm doing wrong here please?

int main(int argc, char* argv[])
{
	int err=0;
	char errstr[256];

	//open and play the video
	mciSendString("open messwiththebest.mpg alias mwtb",0,0,0);
	mciSendString("play mwtb",0,0,0);
	//pause the movie when user hits a key
	getch();
	mciSendString("pause mwtb",0,0,0);
	//try to get a capture
	err = mciSendString("capture mwtb E:\\capture.jpg",0,0,0); //error no: 259 is returned
	mciGetErrorString(err,errstr,256);

	return 0;
}

It seems that you forgot to provide the last parameter.

i've tried the capture command with the 'wait' parameter. but it gives the same error msg.

I think you're missing the "as":

err = mciSendString("capture mwtb as E:\\capture.jpg wait",0,0,0);
