• Java, Linux : 2nd call to ffmpeg via Runtime not getting executed

  21 février 2018, par We are Borg

  I am trying to convert video to gif. I am using ffmpeg and imagemagick to achieve this. The first step is successful where a mp4 is created, but the 2nd process is not getting called. If I run the command manually, then it all works fine, but not via code. What am I doing wrong ? Thank you.

  Error log :

  First path is ffmpeg -i /media/attachment/test/groupattach/200/5mpnkfiq4f635m2j663sb5dne -ss 05 -t 10 -c copy /media/attachment/test/groupattach/200/tsr8svjtvqa4alm5vls9v0pgc4.mp4
  
  Third path is ffmpeg -i /media/attachment/test/groupattach/200/tsr8svjtvqa4alm5vls9v0pgc4.mp4 -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -loop 0 - /media/attachment/test/groupattach/200/f9b4cmkhhpm180sau7f7j7j1ai.gif

  Service layer where I get error :

  if (extension.toLowerCase().equals("mp4")) {
  
                      String videoPath = createPreviewForVideos(attachId, fileBytes, filesPath, fileName);
  
                      return FileUtils.readFileToByteArray(new File(videoPath));
  
  
  
                  }

  This happens because the 2nd part of code is not executed posted below.

  private String createPreviewForVideos(int attachId, byte[] fileBytes, String filePath, String fileName) {
  
          try {
  
              GroupAttachments groupAttachments = this.groupAttachmentsDAO.getAttachmenById(attachId);

              String gifName = String.valueOf(new BigInteger(130, random).toString(32)) + ".gif";
  
              String firstpath = "ffmpeg -i " + filePath + " -ss 05 -t 10 -c copy " + gifLocation + videoName;
  
              System.out.println("First path is " + firstpath);

              Process thirdProcess = Runtime.getRuntime().exec(thirdPath);
  
              thirdProcess.waitFor();
  
              thirdProcess.destroy();
  
              thirdProcess.destroyForcibly();
  
              if(thirdProcess.isAlive()){
  
                  thirdProcess.destroyForcibly();
  
              }
  
              // return gifLocation+gifName;
  
              return secondPhaseForVideos(attachId, fileBytes, filePath, fileName, videoName, gifName);
  
          } catch (Exception e) {
  
              e.printStackTrace();
  
          }
  
          return null;
  
      }
  
  
  
      private String secondPhaseForVideos(int attachId, byte[] fileBytes, String filePath, String fileName, String videoName, String gifName) {
  
          try {
  
              GroupAttachments groupAttachments = this.groupAttachmentsDAO.getAttachmenById(attachId);

              String thirdPath = "ffmpeg -i " + gifLocation + videoName + " -vf scale=320:-1 -r 10 -f image2pipe -vcodec ppm - | convert -loop 0 - " + gifLocation + gifName;
  
              System.out.println("Third path is "+thirdPath);
  
              Process process = Runtime.getRuntime().exec(thirdPath);
  
              process.waitFor();
  
              process.destroy();
  
              groupAttachments.setFullSizePath(gifName);
  
              this.groupAttachmentsDAO.updateAttachment(groupAttachments);
  
              return gifLocation + gifName;
  
  
  
          } catch (Exception e) {
  
              e.printStackTrace();
  
          }
  
          return null;
  
      }

  2nd phase code never gets executed...the Runtime process. What am I doing wrong ? Thank you.
