sorry about my lower english I'm south korean, but I think you can read it

When i get H.264 video stream with RTSP, I have prablem with getting decend image.

In code

I use cvWaitKey(1) 1~100 for synchronize cameras buffer and cvQueryFrame()

I think this problem is just TIME problem But I don't know how get signal of Camera's buffer is written.

int cnt = 0;
int count = 0;
IplImage *img[MAXCAM];
CvCapture *camera[MAXCAM]; 
CString numFrame[MAXCAM];

/// 임의 영역 
//camera[0] = cvCreateFileCapture("rtsp://127.0.0.1:951/everyone"); 
//camera[1] = cvCreateFileCapture("rtsp://admin:[email protected]:554/channel1"); 
camera[0] = cvCreateFileCapture("rtsp://admin:[email protected]:554/channel1"); 
camera[1] = cvCreateFileCapture("rtsp://127.0.0.1:951/everyone"); 


for (cnt = 0 ; cnt<MAXCAM; cnt++ ) {
    if (camera[cnt] == NULL) {
        return -1;
    }
    numFrame[cnt].Format("CAM %d", cnt);
    cvNamedWindow(numFrame[cnt]);;
}   

while (cvWaitKey(1) != 27) {        /// cvWaitKey 가 보내주는 bitrate 에 맞추어 출력하지 못할경우 이미지 일그러짐 현상 
    //for ( cnt = 0; cnt < MAXCAM ; cnt ++ ) {
        img[1] = cvQueryFrame(camera[1]); 
        //if (img[cnt] == NULL)  
        //  return -2;          
        cvShowImage(numFrame[1], img[1]);
    //}
}

for (cnt = 0; cnt < MAXCAM; cnt++) {
    cvReleaseCapture(&camera[cnt]);
    cvReleaseImage(&img[cnt]);
}
return 0;
