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