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.

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!

I have the same problem! There is the answer?

No answer to this question.

You can build on your computer?

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)?

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)

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.

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.

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

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.

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.

I can't update opecv because i working in visual studio 2005.

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:

But it should be this:

Please help me! Thanks.

There was a problem in the old library ffmpeg.

I use OpenCV 2.3.1. I am trying get video from IP Camera (rtsp protocol) but get the following error:

IplImage* frame;   
CvCapture* cam = cvCaptureFromFile("rtsp://admin:[email protected]/defaultPrimary?streamType=u");    while(true)
{               
    frame = cvQueryFrame(cam);          
    cvShowImage("Test", frame);
    if (cvWaitKey(10) == 27){
            break; }
}

In the console I get errors and poor quality video!

Thank you!

I can't update my compiler.

Hi. I working in Visual Studio 2005. I want to use OpenCV 3.0 but i did not found duild version for Visual Studio 2005. Where can I download OpenCV 3.0 for Visual Studio 2005?
