No Audio in the output file

[shaikmdashiq]

I am using the MP4ParserMergeAudioVideo to add a new audio to an MP4 file

findViewById(R.id.append).setOnClickListener(new OnClickListener() {
@OverRide
public void onClick(View v) {
String root = Environment.getExternalStorageDirectory().toString();
Log.e("",""+root);
String audio = root + "/download/"+"mymovieaudio.m4a";
String video = root + "/download/"+"My_Movie.mp4";
String output = root + "/download/ouput.mp4";
mux(video, audio, output);
}
});

I successfully get the output.mp4 file in my download directory of my device. The problem is that it does not have any audio. Please help. Thanks in advance.

Can you public full project's source code?

[shaikmdashiq]

I have no modifications in your code.... I had used just the same....

findViewById(R.id.append).setOnClickListener(new OnClickListener() {
@OverRide
public void onClick(View v) {
/*
mProgressDialog = ProgressDialog.show(self, null, null);
Bundle args = new Bundle();
args.putInt("type", 0);
getSupportLoaderManager().initLoader(0, args, self);
*/
String root = Environment.getExternalStorageDirectory().toString();
//this is a .m4a file, not converted from wav. Its by default a .m4a
String audio = root + "/download/"+"sample2.m4a";
String video = root + "/download/"+"My_Movie.mp4";
String output = root + "/download/ouput1.mp4";
Log.e("FILE", "audio:"+audio + " video:"+video+ " out:"+output);
mux(video, audio, output);
}
});

public boolean mux(String videoFile, String audioFile, String outputFile) {
Movie video;
try {
video = new MovieCreator().build(videoFile);
} catch (RuntimeException e) {
e.printStackTrace();
return false;
} catch (IOException e) {
e.printStackTrace();
return false;
}

    Movie audio;
    try {
        audio = new MovieCreator().build(audioFile);
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    } catch (NullPointerException e) {
        e.printStackTrace();
        return false;
    }

    Track audioTrack = audio.getTracks().get(0);
    video.addTrack(audioTrack);

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

    FileOutputStream fos;
    try {
        fos = new FileOutputStream(outputFile);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return false;
    }
    BufferedWritableFileByteChannel byteBufferByteChannel = new BufferedWritableFileByteChannel(fos);
    try {
        out.writeContainer(byteBufferByteChannel);
        byteBufferByteChannel.close();
        fos.close();
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }
    return true;
}

I get the output file, but there is no change in it. It has the same audio of the video which I loaded but the length of the video is increased to the length of the audio file. Nothing else.

Please help. I tried all ways, I am broke. Pls...

If you cannot resolve the problem.... Please let me know... Don't make me wait... i have asked you in StackOverflow also and there is no response from u... Pls dont be rude to others... If thr is no solution try to say it and admit that your library is useless...

[tqnst]

Please show me full source code of your project, combine your audio and video file.
This is only a demo for merge audio to video(not library)

[shaikmdashiq]

There is no changes from your source code. I have just used my .m4a file and .mp4 file and it does not mux. No errors by the way. But the audio is not merged. Its the same audio which is in the video which comes in the output. If you still want to see the source code. Here is the dropbox link. Have fun.

Okie, tonight I will check it for you. Now I must work other task.

[shaikmdashiq]

hello...

[illiaKalu]

I have the same issue, virtal46, did u solve the problem ?

[illiaKalu]

I tried to add audio to the silent video, to the video with sound - no result. The video and an audio file are the same length

[shaikmdashiq]

Yes you need to change something like this, before writing to the output
Track audioTrack = audio.getTracks().get(0);
Track videoTrack = video.getTracks().get(0);

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

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

doesnt work =( can you check out my code or share yours (dropbox link doest work) ?
Movie video;
