Replace Audio of a Video with diff AAC audio

Hey nice lib, I want to replace the audio of a mp4 video with other aac audio(which i have recorded using phones mic) in Android.

                    String accFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.acc";
                    String videoFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myvid.mp4";

                    Movie m = MovieCreator.build( new FileDataSourceImpl(videoFileName));
                    List<Track> nuTracks = new ArrayList<>();
                    for (Track t : m.getTracks()) {
                        // Re-use all tracks besides the audio track
                        if (!"soun".equals(t.getHandler())) {
                            nuTracks.add(t);
                        }
                    }
                    Track nuAudio = new AACTrackImpl(new FileDataSourceImpl(accFileName));
                      //giving error on the above line "Expected Start Word 0xfff"
                    nuTracks.add(nuAudio); // add the new audio track
                    m.setTracks(nuTracks);
                    String outputFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/output.mp4";
                    Container c = new DefaultMp4Builder().build(m);
                    c.writeContainer(new FileOutputStream(outputFileName).getChannel());

And what is diffrence btwn raw aac and normal aac ? @sannies

It’s as expected. It’s an MPEG4 container and no raw file. Use the MovieCreator.build() and simply use the first track. That should do the trick.

I am using android device to capture this audio. Using output format as 3gp and audio encoder as aac. On Jan 10, 2016 12:51 AM, “priyank agrawal” < [e-mail]

Hi, could you check what kind of AAC you recorded. There are two variant of ‘raw’ AAC:

• fltp or (aac version 4) which is very uncommon in my eyes (not supported!)
• and ADTS Could you use mediainfo on your file to see what it is?
