  • Sample RTP code to stream x264 data

    5 août 2016, par Ajay Ponna Venkatesh

    I am using x264 library to encode frames and I need to stream it to a client which will receive the frame, decode and render it.
    Currently, I have borrowed the code from OBS to stream through RTMP and have written a client using FFMPEG’s RTMP code to receive this data. BUT RTMP works on TCP and I now need to stream over UDP. OBS doesn’t seem to support any other protocols than RTMP.

    So, I decided to use RTP. I can write a client to receive and decode using FFMPEG since it supports RTP just like RTMP. Can anyone please help me with sample code to stream x264 encoded data through plain RTP ? (I don’t want to complicate by using RTSP etc. along with RTP).

    The requirement is simple. Say, I use ffplay -> ffplay.exe rtp ://127.0.0.1:17000 then I want this sample code to be able to send data through RTP (over UDP) and ffplay should be able to play. I can take it over from there. Thanks in advance !

  • How to optimize YUV to RGB color conversion code

    1er février 2016, par user_12

    I have written a function to convert an image in YUV420P to RGB but it is taking 30 millisecond to convert an image (size : 1280 x 720) into RGB, but when I am using ffmpeg function ( as this) to convert YUV image into RGB its taking only 2 millisecond for the same image. What is the problem with my code ? How can I optimize the code that I have written ??
    My code is given below

     int step = origImage->widthStep;
    
 uchar *data = (uchar *)origImage->imageData; 
    
 int size = origImage->width * origImage->height;
    
 IplImage* img1 = cvCreateImage(cvGetSize(origImage), IPL_DEPTH_8U, 3);
    

    
    for (int i = 0; iheight; i++)
    
    {
    
      for (int j=0; jwidth; j++)
    
      {
    
        float Y = data[i*step + j];
    
        float U = data[ (int)(size + (i/2)*(step/2)  + j/2) ];
    
        float V = data[ (int)(size*1.25 + (i/2)*(step/2) + j/2)];
    

    
        float R = Y + 1.402 * (V - 128);
    
        float G = Y - 0.344 * (U - 128) - 0.714 * (V - 128);
    
        float B = Y + 1.772 * (U - 128);
    

    

    
        if (R < 0){ R = 0; } if (G < 0){ G = 0; } if (B < 0){ B = 0; }
    
        if (R > 255 ){ R = 255; } if (G > 255) { G = 255; } if (B > 255) { B = 255; }
    

    
        cvSet2D(img1, i, j,cvScalar(B,G,R));
    
      }
    
    }
