• FFMPEG commands isn't working in Android Q

  5 février, par Krupali Shingala

  Try this command for merge two audio files, but its not working in Android 10.0(Q) while targeting sdk 29.
But, this command is completely working on targeting sdk 24 to 28.

  



  I am using this library of FFMPEG implementation 'nl.bravobit:android-ffmpeg:1.1.7'

• 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
