• FFMPEG output file does not contain any stream [Android] video concat

  22 février 2017, par Akshay Sood

  I have been trying to merge (concatenate) two mp4 videos with same height and width but some error occurs. It says the output file doesnot have any stream.
  Please help.
  The code is written below :

  String[] arg = new String[]{
  
                  ActualVideoFile.getAbsolutePath(), path
  
          };
  
          String list = generateList(arg);
  
          String[] command = new String[]{
  
                  " -f concat -i " + list + " -c:v copy " + mergedVideo.getAbsolutePath()
  
          };
  
          try {
  
              ffmpeg.execute(command, new FFmpegExecuteResponseHandler() {
  
                  @Override
  
                  public void onSuccess(String message) {
  
                      Log.e("SUCCESS", message);
  
                  }
  
  
  
                  @Override
  
                  public void onProgress(String message) {
  
                      Log.e("onProgress", message);
  
                  }
  
  
  
                  @Override
  
                  public void onFailure(String message) {
  
                      Log.e("onFailure", message);
  
                  }
  
  
  
                  @Override
  
                  public void onStart() {
  
                      Log.e("onStart", "start");
  
                  }
  
  
  
                  @Override
  
                  public void onFinish() {
  
                      Log.e("FINISH", "FINISHED");
  
  
  
                  }
  
              });
  
          } catch (FFmpegCommandAlreadyRunningException e) {
  
              e.printStackTrace();
  
          }

• Bash script stops execution of ffmpeg in while loop - why ?

  20 novembre 2020, par Alex Monthy

  I have this bash script for converting .mp4 video to .mp3 audio.
It runs, but does the loop only once, though there are more mp4 files in /home/myname/mp4dir.

  



  The script converts the first .mp4 file it finds to .mp3, unless there is already an .mp3 file. This should be done in a loop, but after the first call to ffmpeg the script stops.

  



  Why ?

  



  #!/bin/bash
find /home/myname/mp4dir -name "*.mp4" | while read f
do
        fOut=`echo $f | sed s/mp4/mp3/`
        echo "convert $f => $fOut"
        if ! test -f $fOut
        then
                ffmpeg -i $f -vn -f mp3 $fOut
        fi
done


  


• PHP Sort Order Proccess Codeiginiter

  20 avril 2015, par Alan El-nino Malmsteen

  i use php codeigniter to manage video using FFMPEG, but i dont know how to delete original video after convertion succesful.

  if(!($_FILES["upload_video"]["type"] == "video/mp4"))
  
      {
  
      $prename = $r.'.'.$ext;
  
      $video = $prename.'.mp4';
  
      $directory_path  = "/home/templates/videos/".$prename;
  
      $directory_path_full = "/home/templates/videos/".$prename;
  
      exec("ffmpeg -i ".$directory_path_full." ".$directory_path.".mp4"); 
  
  
  
      // Delete original format video
  
      $this->load->helper("file");
  
      unlink($directory_path_full); 
  
  
  
      }else{
  
      $video = $r.'.'.$ext;
  
      }

  When i use "unlink" it work good to delete file, but the video is corrupt (maybe php directly delete it when converting progress)
  So, can you help me to create sort order php process for this case ?

  Thanks
