• FFmpeg - Buffer queue overflow, dropping - when combining 2 videos and using concat, hstack and trim

  23 août 2018, par Mayank

  I am trying to merge two videos using concat and hstack but getting buffer overflow error resulting in the one of the video getting paused for few seconds.

  I tried adding fifo and h264 video codec as suggested on this forum but the issue persists.

  Can someone please let me know the issue in this command ? Many thanks in advance.

  ffmpeg -i 1_a.opus -i 2_a.opus -i 1_v.mp4 -i 2_v_bars.mp4 -filter_complex "[1:a]adelay=15720|15720[a1]; [0:a][a1]amix; [3:v]trim=0:15.81,geq=0:128:128,fifo [silence]; [silence][3:v]concat,fifo [3_v_silence]; [3_v_silence][2:v]hstack,fifo" -vcodec libx264 -strict experimental -y out_fifo_h264_2.mp4

• Changing Audio Volume using FFmpeg Android Error

  23 août 2018, par kataroty

  I am using FFmpeg and I need to change the volume of the Audio.

  This is the command that should change the volume of the audio :

  ffmpeg -i input.wav -filter:a "volume=1.5" output.wav

  I read from somewhere that it had to overwrite the file if it already existed so either one had to delete the file or use -y. When I tried to do it without the -y command it never got to onSuccess() or ´onFailure(), but it always printed out the onStart() message.

  String[] cmdy = { "-i -y" , pcmtowavTempFile.toString(),  "-af", "volume=5", pcmtowavTempFile.toString()};
  
      ffmpeg.execute(cmdy, new ExecuteBinaryResponseHandler() {
  
  
  
          @Override
  
          public void onStart() {
  
              System.out.println("ayy: onStart");
  
          }
  
  
  
          @Override
  
          public void onSuccess(String message) {
  
              System.out.println("ayy: onSuccess");
  
              super.onSuccess(message);
  
          }
  
          @Override
  
          public void onFailure(String message) {
  
              System.out.println("ayy: onFailure " + message);
  
              super.onFailure(message);
  
          }
  
  });

  At the moment I get this error :

  Unrecognized option 'i -y'.

  Which clearly states that it does not recognize option i -y, but also as I said earlier then if I remove the -y it never gets to onSuccess() or onFailure().

  help me to find a solution. Thanks.
