• add a part of an audio file to a certain part of video , in loop using FFmpeg

  5 octobre 2017, par 1234567

  I have two files one Audio and one video file,

  The audio file is 1 min long,

  and the video file is 2 min 30 sec long,

  I want to add a part of audio, with loop not the whole audio file to the video , using FFmpeg

  say from 15 sec to 33 sec of the audio file

  to a part of video say from 45 sec to 1min 30 sec

  this code has worked with a single file which is 18 sec long , which is added to a certain part of video with a loop

  "-y","-i",j,
  
                          "-filter_complex",
  
                          "amovie="+audio+":loop=999,asetpts=N/SR/TB," +
  
                                  "atrim=0:45,adelay=45000|45000,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.5[a1];" +
  
                                  "[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=2.0[a2];" +
  
                                  " [a1][a2]amerge,pan=stereo:c0code>

  the problem is If I have a 1 min long audio file and just want to extract a 18 sec part form it , and add it to video in a loop how can that be done

• ffmpeg freezes some part of video using android ffmpeg

  13 octobre 2017, par Tushar Pingale

  When i am Creating video parts, ffmpeg freezes some parts of the video, mostly the end part of the video. The command i am using for ffmpeg is as follows :

  public void doSplitting(String path, long start, long duration, String outputPath) throws FFmpegCommandAlreadyRunningException {
  
      new File(outputPath).getParentFile().mkdirs();
  
      String newpath = generateFromKitkat(path);
  
      String[] complexCommand = new String[]{"-i", newpath, "-itsoffset", "0.10", "-i", newpath, "-ss", ((int) (start / 1000)) + "", "-t", ((int) (duration / 1000)) + "", "-vcodec", "copy", "-acodec", "copy", "-map", "0:0", "-map", "1:1", outputPath};
  
      String logMessage = "";
  
      for (String str : complexCommand) {
  
          logMessage = logMessage + " " + str;
  
      }
  
      Log.d("Complex Command", logMessage);
  
  //ffmpeg Execution
  
  
  
  }
