Open sruthipg opened 6 years ago

sruthipg commented 6 years ago

I am executing the following command to merge two audio file:

ffmpeg -i /storage/emulated/0/AudioRecorder/1519635839069.mp3 -i /storage/emulated/0/AudioRecorder/SampleAudio_0.4mb.mp3 -filter_complex amix=inputs=2:duration=first:dropout_transition=2 /storage/emulated/0/AudioRecorder/1519710922139.mp3

but I am getting the following error

Finally I found the solution String s="-i "+mFileTemp.getPath()+" -i "+mFileTemp2.getPath()+" -i "+mFileTemp3.getPath()+" -filter_complex [0:0][1:0][2:0]concat=n=3:v=0:a=1[out] -map [out] "+originalFile.getPath(); String [] ss= s.split(" "); Pass this array to ffmpeg.execute(..). This works for me.

Hi @sruthipg I was getting the following error message while concat three audio files Invalid file index 2 in filtergraph description [0:0][1:0][2:0]concat=n=3:v=0:a=1[out]

Please let me know if there any solutions available for this?
