2017-03-21 08:52:16 -0500 commented question Read video stream from VLC plyaer

If I use command line ffmpeg -i rtsp://@127.0.0.1:18554/streamer -acodec copy -vcodec copy c:/events/abc.mp4 then it works fine.

2017-03-21 08:27:04 -0500 asked a question Read video stream from VLC plyaer

Hello!

I get a stream from the camera using the RTSP protocol.

    int main()
    {
     std::stringstream fmt;
fmt << "rtsp://" << "127.0.0.1" << ":" << "18554" << "/" << "streamer";

m_url = fmt.str();
    int count = 0;
double fps = 0.0;
bool isExit = false;
Mat frame;

std::string displayName_1 = "Display window_1";

namedWindow(displayName_1, WINDOW_NORMAL);// Create a window for display.   
resizeWindow(displayName_1, 400, 400);

do {
    std::cout << std::endl << " Try connection to camera: " << +m_url.c_str() << std::endl;
    VideoCapture cam(m_url.c_str());

    while (true)
    {
        count++;

        if (!cam.read(frame)) {
            printf(" Not get frames from camera %s\n", m_url.c_str());
            if (count >= 10) {
                count = 0; break;
            }
            continue;
        }

        if (frame.data) {
            imshow(displayName_1, frame);                   // Show our image inside it.            }
        else
        {
            printf("Failed to get frames from the camera!!! count %d of 10 \n", count);
            if (count == 10) {
                count = 0;
                break;
            }
        }

        if (cvWaitKey(10) == 27) {
            isExit = true;
            break;
        }

    }
} while (!isExit);
}

Works great.

Now I need to write a simulation of the camera.

In the VLC player, I read the video file and send it to the stream. (:sout=#rtp{sdp=rtsp://:18554/streamer} :sout-all :sout-keep)

When I try to read the stream, I get an error - "[rtsp @ 000002a02cead760] method SETUP failed: 461 Client error"

How can this problem be solved. Thank you!

There's a lot of information. Maybe copy something specific?

that is kind of bogus, does not compile actually means that you could not compile it. Please add the errors and we will walk you through it! Do you understand what the problem is ??

Thank you very much! I have another question. How to get a time of frame (hh.mm.ss.millisecond)?

2015-06-29 07:03:08 -0500 commented question How to read pixel every frame?

To be honest I don't know what you're asking or what you want us to resolve, and I don't think anyone does at this point. How can I add text to a frame and save to disk? (using opencv)

2015-06-29 06:59:24 -0500 commented question How to read pixel every frame?

Why would you not be able to do it? You will need to rebuild opencv yourself, but it should work just fine. I tried to compile version 3.0.0 but for VS 2005 does not compile.

2015-06-29 06:56:02 -0500 commented question How to read pixel every frame?

Once again, you can add text to a frame and save it as bmp file without using cimg. If we're not understanding your problem, please give more details. Of course I can use Opencv but then it will not match the design of the program. If it does not I will use Opencv.

2015-06-29 05:58:20 -0500 commented question How to read pixel every frame?

This design. I have the function of receiving a frame (char*) this function adds a text in frame, and writes in the BMP file.

2015-06-29 03:40:27 -0500 commented answer How to read pixel every frame?

I know about it! But I have a lot of cameras, not all cameras work with opencv. And before writing to the disk, I must add text to image bmp. Thank you.

2015-06-29 03:31:58 -0500 commented question How to read pixel every frame?

No, because I have a lot of cameras, not all cameras work with opencv. And before writing to the disk, I must add text to image bmp.

2015-06-29 02:53:36 -0500 asked a question How to read pixel every frame?

Hello!

I using Opencv 2.3.1 and cimg!

I need to read every frame with IP camera and record it into the BMP file.

I have the following code:

       Mat frame;
    VideoCapture cam("rtsp://admin:[email protected]/defaultPrimary?streamType=u");
    while(true)
    {   
        if (!cam.read(frame))
            continue;

        count++;
        cimg_library::CImg<unsigned char>* m_frameData = new cimg_library::CImg<unsigned char>(1920, 1080, 1 , 3);

        if (frame.data)
        {
            cvtColor(frame, frameRGB, CV_BGR2RGB);
            uchar* pixelsRGB = frameRGB.data;

            for (unsigned int x = 0; x < frame.rows; x++)               
            {
                for (unsigned int y = 0; y < frame.cols; y++)   
                {                       
                    m_frameData->atXYZC(x,y,0,0) = (int) pixelsRGB[ y + x];
                    m_frameData->atXYZC(x,y,0,1) = (int)pixelsRGB [ y + x + 1];
                    m_frameData->atXYZC(x,y,0,2) = (int) pixelsRGB[ y + x + 2];
                }
            }

            std::string fileWrite = "C:\\Temp\\out" +count+ ".bmp";             
            m_frameData->save_bmp(fileWrite.c_str());

            delete m_frameData;
     }

When I open the BMP file I get: image description

But it should be this: image description

Please help me! Thanks.
