• h264 : postpone generating the implicit MMCOs

  h264 : postpone generating the implicit MMCOs
  Do it right before the MMCOs are applied to the DPB. This will allow
  
  moving the frame_start() call out of the slice header parsing, since
  
  generating the implicit MMCOs needs to be done after frame_start().

• JavaCV FFmpegFrameRecorder Video output reddish color

  14 juin 2016, par Diego Perozo

  I am trying to make a video .mp4 file out of a group of images using FFmpegFrameRecorder as a part of a bigger program, so I set up a test project in which I try to make a video out of 100 instances of the same frame at 25fps. The program seems to work. However, every time I run it the image seems to be reddish. As if a red filter had been applied to it.

  Here’s the code snippet :

  public static void main(String[] args) {
  
      File file = new File("C:/Users/Diego/Desktop/tc-images/image0.jpg");
  
      BufferedImage img = null;
  
      try {
  
          img = ImageIO.read(file);
  
      } catch (IOException e1) {
  
          e1.printStackTrace();
  
      }
  
      IplImage image = IplImage.createFrom(img); 
  
      FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("C:/Users/Diego/Desktop/tc-images/test.mp4",1920,1080); 
  
      try { 
  
      recorder.setVideoCodec(13);
  
      recorder.setFormat("mp4");
  
      recorder.setPixelFormat(0);
  
      recorder.setFrameRate(25);
  
      recorder.start(); 
  
      for (int i=0;i<100;i++){ 
  
      recorder.record(image); 
  
      } 
  
      recorder.stop(); 
  
      } 
  
      catch (Exception e){ 
  
      e.printStackTrace(); 
  
      } 
  
  }

  I’d appreciate it if anybody told me what’s wrong. Thanks in advance for any help.
