• FFProbe doesn't work

  24 février 2018, par Royal.O

  Argument /storage/emulated/0/Watermark/test.flv provided as input filename, but ffprobe was already specified.
  compile 'nl.bravobit:android-ffmpeg:1.1.1

             String [] command = {"ffprobe", videoPath };
  
             FFprobe ffprobe = FFprobe.getInstance(this);
  
  
  
              try {
  
              ffprobe.execute(command, new ExecuteBinaryResponseHandler() {
  
  
  
                  @Override
  
                  public void onSuccess(String message) {
  
                      addTextViewToLayout("SUCCESS with output : "+ message);
  
                      Logger.print("onSuccess : "+message);
  
  
  
                  }
  
                  @Override
  
                  public void onProgress(String message) {
  
                      addTextViewToLayout("Started command : ffmpeg "+command);
  
                      addTextViewToLayout("progress : "+message);
  
                      Logger.print("Started command : ffmpeg "+command.toString());
  
                      Logger.print("progress : "+message);
  
                  }
  
  
  
                  @Override
  
                  public void onFailure(String message) {
  
                      Logger.print("FAILED with output : "+message);
  
                  }
  
  
  
                  @Override
  
                  public void onStart() {
  
                      Logger.print("onStart");
  
                  }
  
  
  
                  @Override
  
                  public void onFinish() {
  
                      Logger.print("onFinish");
  
                  }
  
  
  
              });
  
          } catch (FFprobeCommandAlreadyRunningException e) {
  
              e.printStackTrace();
  
          }
  
  
  
  
  
      }

  ffprobe works good in Windows, Mac, Ubuntu but doesn’t work in Android.

  If anybody experienced please share me your experience.

• How can I play audio file(.mp3, .flac, .wav) and then loop over it (mix every few seconds) another audio file(wav) using ffmpeg

  11 mars 2019, par lukistar

  I got two different commands.

  ffmpeg -i input.mp3 -i second.mp3 -filter_complex "[0:a]atrim=end=10,asetpts=N/SR/TB[begin];[0:a]atrim=start=10,asetpts=N/SR/TB[end];[begin][1:a][end]concat=n=3:v=0:a=1[a]" -map "[a]" output

  This command inserts second.mp3 into input.mp3. It seems to always keep the parameters of input.mp3. It inserts it in exact 10 seconds of input.mp3.

  Here is the second command :

  ffmpeg -i input.mp3 -i second.mp3 -filter_complex "[1:a]adelay=10000|10000[1a];[0:a][1a]amix=duration:first" output

  This command is closer to my final goal. It plays input.mp3 and in exact 10 seconds it plays along second.mp3 without stopping input.mp3’s sound.(I think that’s called mixing ?)

  My final goal is to create final.mp3.

  Its duration must always equal input.mp3 duration. It must keep the samplerate, the count of channels, etc of input.mp3

  When playing final.mp3, it must play the whole input.mp3.
  But each 10-15 seconds, it must play second.mp3 without stopping input.mp3.(mix)
  It could be said that I must use "Second command" but in a loop.
  It would be great if there is one-line command for that in ffmpeg.
  I am working with flac, mp3 and wav and both of the commands were suitable for that.

  For example :

  input.mp3 could be 40 seconds long.

  second.mp3 could be 2 seconds long.

  When I play final.mp3 it will be 40 seconds long, but each 10-15 seconds(on random) it will play second.mp3 at the same time as input.mp3.

  Sadly I have no experience with ffmpeg, both of the commands I got are answers to questions here in stackoverflow. Hope somebody can help me. Thank you !

• When merging video and audio, converting audio to AAC, sound is missed at the end 3 seconds

  10 octobre 2013, par profuel

  I have to build video from images and some audio clip.
  Audio is much longer, so I have to mute last 5 seconds of audio track, cutting to video length.
  My issue is that adding AAC encoding to audio removes last 2-5 seconds of audio in resulted video.
  
  Here are my command lines :

  ffmpeg -i sound.mp3 -i video.mp4 -shortest out.mp4 -> results in correct audio in result video with played audio over 100% of movie

  ffmpeg -i sound.mp3 -i video.mp4 -acodec aac -ab 160000 -strict experimental -shortest out.mp4 -> not correct audio, gets crop at end of video for 2-5 seconds
  
  
  The problem appears for me both on Windows and on CentOS 6.4, no matter which version of ffmpeg is used.
