Expected Start Word 0xfff

Hello, excuse me for my bad english. I want to merge in the same file two audios (one is music, and the otherone is an audio file record with the mobile) I don´t want append, i want that i can listen music and voice at the same time. I was trying to use:
AACTrackImpl aacTrack = new AACTrackImpl(new FileDataSourceImpl("audio.aac")); But always receive the same error, with the music and with de audio recorder… Expected Start Word 0xfff My audio is record with mediaMuxer and mediacoder. How can i solve that? i don´t know what else find and test. Thank You so much.

Hi, I had the same issue with " Expected Start Word 0xfff", but I found a solution.

It seams that MediaMuxer creates a container (mp4) so you just need to use the Movie class not the AACTrackImpl

        Movie video = MovieCreator.build(videoFile.getAbsolutePath());
        Track videoTrack = video.getTracks().get(0);


        Movie audio = MovieCreator.build(audioEncodedFile.getAbsolutePath()); // here
        Track audioTrack = audio.getTracks().get(0);

        Movie movie = new Movie();
        movie.addTrack(videoTrack);
        movie.addTrack(audioTrack);

        Container out = new DefaultMp4Builder().build(movie);

// ...

I got this same issue, I’m using AAC audio file to merge with an mp4 video file.

Track nuAudio = new AACTrackImpl(new FileDataSourceImpl(audio));
