• Pausing video streaming at EOF with FFMPEG ( Streaming and saving simultaneously)

  6 novembre 2019, par Padfoot

  I am writing a video to a local file using videowriter in OpenCV and at the same time, I am streaming it using ffmpeg+RTSP.
  But my video writing is slower than streaming. So RTSP is reaching the EOF and streaming is stopped.

  Is there any way or option in FFMPEG to pause the stream if it reached EOF and resumes again from the same time point.

  EDIT

  System - Ubuntu 16, 32 GB RAM.

  For video writing (frame by frame) -

       int i = 0;
  
  
  
      VideoWriter video("output.mp4",CV_FOURCC('a','v','c','1'),25, Size(frame_width,frame_height)); 
  
          while(1)
  
          { 
  
              Mat frame; 
  
  
  
              cap >> frame;
  
  
  
              if (frame.empty())
  
              break;
  
  
  
              video.write(frame);
  
  
  
      if (i == 25)
  
      printf("Start streaming");
  
  
  
       i++;
  
  
  
  
  
          }

  After writing 25 frames, I am streaming through -

  ffmpeg -re -i output.mp4 -codec copy -f flv rtmp://192.168.0.1:1935/live
