How to play a .mov from a rtsp

edit

Hi, i am trying to play from a wifi camera that streams on .mov file using rtsp, i get the image but it arrives distorsionated, sometimes pixelates sometimes green and sometimes without errors, while i am playing it i get the following messages in the bash:

    left block unavailable for requested intra mode at 0 29
[h264 @ 0x1e5af00] error while decoding MB 0 29, bytestream (-1)
[h264 @ 0x1e5b4c0] left block unavailable for requested intra mode at 0 29
[h264 @ 0x1e5b4c0] error while decoding MB 0 29, bytestream (-1)

to see the images the camera captures i am using this

 cv::VideoCapture capture("rtsp://192.168.1.254/sjcam.mov");
if (!capture.isOpened()) {
        //Error
    }

    cv::namedWindow("TEST", CV_WINDOW_AUTOSIZE);

    cv::Mat frame;

    for(int i =0; i<50000;i++) {
        if (!capture.read(frame)) {
            //Error
        }
        cv::imshow("TEST", frame);

        cv::waitKey(30);
    }

I do not know what else can i do, or where is the problem, i have tried to play .mov videos using opencv and i do it without problems, so i suppose i am doing something wrong with the rtsp thanks a lot
