Expected Start Word 0xfff

[garodev]

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.

Same here

Hello, I got the same error any solution? my audio file is a wav I've recorded.

The AACTrackImpl can read a raw AAC track. I cannot read a wav track nor convert wav to aac.

I got the same issu after converting to m4a.

` My outpu file seems to bo correct and I have the "Expected Start Word 0xfff" exception.

Hello Sannies , I`m getting the same exception. Can u help me out in this? Please check my below code.

---

val movie = MovieCreator.build(videoPath) //val ct = CroppedTrack(getAudioTrack(), 10, 500) val track = getAudioTrack() // below you will get getAudioTrack methode movie.addTrack(track)

        val mp4file = DefaultMp4Builder().build(movie)
        val fc = FileOutputStream(File(filePath)).channel
        mp4file.writeContainer(fc)
        fc.close()

---

private fun getAudioTrack(): Track { val track = FileDataSourceImpl(audioPath) var audio: Track? = null

    if (audioPath.contains(".mp3")) {
        readTags()
        //val audioPath = removeTags()
        audio = MP3TrackImpl(track)
    } else if (audioPath.contains(".aac")) {
        audio = AACTrackImpl(track)
    }
    return audio!!
}

Same error, Did you fix this error?

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.

W/System.err: java.io.IOException: Expected Start Word 0xfff at com.googlecode.mp4parser.authoring.tracks.AACTrackImpl.readADTSHeader(AACTrackImpl.java:291)

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