Android - combining two MP4 files

I'm writing an Android project where I'm recording several audio files. Therefore, I'm setting the following parameters. The recording works fine. 

recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);

My problem is that each time I record, the output is written in a separate file. Now, I need to combine these files to one file. Does anyone have an idea how to combine several MPEG 4 files in an Android project?

Thanks for your help....

Solution

  • In android there is no any inbuilt functionality for combining two audio files, If you are done it through any file operation then this also down to work because its not working as the headers of audio files are different.

    I recommended to use a external library FFMPEG for your android application.
