• Rotate 360 video with ffmpeg

  9 septembre 2019, par Leos Literak

  I have 360° video and I want to fine tune its orientation with ffmpeg. I need to rotate it by 90° clockwise horizontally (turn it left). I found some helpful resources stating that the rotate filter would do the trick. So I tried :

  ffmpeg -i Petr_doskok.mp4 -vf "scale=2048x1024,rotate=-PI/2"  -r 30 -c:v libx265 -b:v 15M -pix_fmt yuv420p -c:a aac -b:a 192K Petr_doskok_rotated.mp4

  Well, the video was really rotated - vertically ! The documentation does not reference the 360° video production : http://ffmpeg.org/ffmpeg-filters.html#rotate. What is the correct parameter value for my case ?

• Record Screen using ffmpeg doesn't work in tomcat server(Could not find codec parameters for stream 0)

  4 septembre 2019, par Norhan Mohamed

  I have the following problem,when I executed the below FFMPEG terminal command in command it prompt successfully.
  
  

      C:\\ffmpeg\\bin\\ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4

  but I have a problem while running a command from a java web application.I used runtime.exec(). It’s working fine at Netbeans. But not working at all after deploying on tomcat server.
  
  Here is my code :

  String command = "C:\\ffmpeg\\bin\\"
  
              + "ffmpeg.exe -f gdigrab -i desktop -c:v libx264 -analyzeduration 15M -probesize 15M -pix_fmt yuv420p -loglevel 99 C:\\ffmpeg\\bin\\video.mp4";
  
  
  
      System.out.println("command = " + command);
  
      try {
  
          Process p = Runtime.getRuntime().exec(command);
  
  
  
          final InputStreamReader isr
  
                  = new InputStreamReader(p.getErrorStream());
  
          Thread th = new Thread() {
  
              public void run() {
  
                  try {
  
                      BufferedReader br = new BufferedReader(isr);
  
                      String line = null;
  
                      while ((line = br.readLine()) != null) {
  
                          System.out.println(line);
  
                      }
  
                  } catch (Exception ex) {
  
                  }
  
              }
  
          };
  
          th.start();
  
      } catch (IOException ex) {
  
          System.out.println("Error 1 : " + ex.getMessage());
  
      } catch (Exception ex) {
  
          System.out.println("Error 2 : " + ex.getMessage());
  
      }

  And here is log for error

• ffmpeg send video to ffserver without reencode, CPU usage still very high.How ?

  3 septembre 2019, par Wayne Chen

  I’m using ffmpeg to send H.264 video to ffserver. Command looks like this :

  ffmpeg -re -stream_loop -1 -i test.mp4 -c copy http://localhost:8090/feed1.ffm

  I thought with -c copy option, the CPU usage of ffmpeg should be very low, but it actually used 99% of CPU.Please help cutdown the usage of CPU.
  Thanks
