java.lang.ArrayIndexOutOfBoundsException: length=8; index=8

[m-o]

Hi, I am having strange problem. I am recording vidoe files from Android surface(originally from GoPro3) and I am adding audio track.
I get exception on some files. I can play those files, ffprobe does not show anything strange. And the error shows only in combination with audio track.

Example:
Load mp4 - load video8, extract video track, add to new Movie, save - ok;
Load mp4 - load video9, extract video track, add to new Movie, save - ok;
Load mp4 - load video8. extract video, add to new Movie, load .aac file, add to movie, ok;
Load mp4 - load video9. extract video, add to new Movie, load .aac file, add to movie, error;

Files are here: https://www.dropbox.com/sh/jvrd5qovoz488du/AACbFSWHNCxqVO1CE1dTwGIca?dl=0

Here is my code:

public void openFiles(){
        String dir = Environment.getExternalStorageDirectory()+"/";
        try {
            String video = dir + "video_track9.mp4";
            Movie originalVideo = MovieCreator.build(video);
            List<Track> tracks = originalVideo.getTracks();
            Track videoTrack = null;
            for (int i = 0; i < tracks.size(); i++) {
                Track t = tracks.get(i);
                if (t.getHandler().equals("vide")){
                    videoTrack = tracks.get(i);
                }
            }
            if(null != videoTrack) {
                Log.d("Main", "start saving: ");
                Uri uri = Uri.parse(dir + "/twentysec.aac");
                AACTrackImpl aacTrack = new AACTrackImpl(new FileDataSourceImpl(uri.getPath()));
                Movie movie = new Movie();
                movie.addTrack(aacTrack);
                movie.addTrack(videoTrack);
                Container mp4file = new DefaultMp4Builder().build(movie);
                FileChannel fc = new FileOutputStream(dir + "test_output_track9.mp4").getChannel();
                mp4file.writeContainer(fc);
                fc.close();
                Log.d("Main", "saving done: " + video);
            }
            else{
                Log.d("Main", "mo video track");
            }
        } catch (IOException e) {
            e.printStackTrace();
            Log.d("Muxing",e.toString());
        }
    }

And here is full exception:

The problem is, I do not know where to look for the error. Is it in video or audio track?
Also, when I tried to use FragmentedMp4Builder - the movie was saved. But library I use for reading the final file had problems reading it, so FragmentedMp4Builder is not a solution for me...
The error log shows error on line:

Container mp4file = new DefaultMp4Builder().build(movie);

Thanks for repsonse!

[m-o]

Edit: I tried to use diferent audio file, and the problems are the same: vide8 ok, video9 error.

[sannies]

Are you using one of the latest builds?
When I do:

public static void main(String[] args) {
    String baseDir = "c:\\users\\sannies\\Downloads\\";
    Movie vt8 = MovieCreator.build(baseDir + "video_track8.mp4");
    Movie vt9 = MovieCreator.build(baseDir + "video_track9.mp4");
    Track audio = new AACTrackImpl(new FileDataSourceImpl(baseDir + "twentysec.aac"));
    vt8.addTrack(audio);
    vt9.addTrack(audio);
    Mp4Builder builder = new DefaultMp4Builder();
    Container c = builder.build(vt8);
    c.writeContainer(new FileOutputStream("vt8.mp4").getChannel());
    c = builder.build(vt9);
    c.writeContainer(new FileOutputStream("vt9.mp4").getChannel());
}

in the master branch both videos just work fine (Do I assume correctly that the audio is silence?)

Would you please try version 1.1.2 from https://oss.sonatype.org/content/repositories/comgooglecodemp4parser-1071/

That should help!

[m-o]

I had version 1.0.6. When I added 1.1.2 I am getting error on both files:

java.lang.NoSuchMethodError: No interface method sort(Ljava/util/Comparator;)V in class Ljava/util/List; or its super classes (declaration of 'java.util.List' appears in /system/framework/core-libart.jar)
            at com.googlecode.mp4parser.authoring.builder.DefaultMp4Builder.createStco(DefaultMp4Builder.java:477)
            at com.googlecode.mp4parser.authoring.builder.DefaultMp4Builder.createStbl(DefaultMp4Builder.java:362)

On line:

Container container = mp4file.build(originalVideo);

And yes, the file is mute. It is just for testing purposses, I will be adding real audio later.

[sannies]

Ohhh my ...
I accidentally used List.sort(Comparator) which is only available in Java 8 and therefore not on Android and earlier version of the JSDK. I'm replacing it with Collections.sort(List, Comparator) and build a new build. Gimme 10 minutes

1.1.3 and
https://oss.sonatype.org/content/repositories/comgooglecodemp4parser-1072

Hi, thank you for the prompt fix. But after I updated the library and cleaned the project, when I try to combine files I get similar error:

 Process: com.example.marek.audiorecorder, PID: 19590
    java.lang.NoSuchMethodError: No interface method sort(Ljava/util/Comparator;)V in class Ljava/util/List; or its super classes (declaration of 'java.util.List' appears in /system/framework/core-libart.jar)

            at com.googlecode.mp4parser.authoring.builder.DefaultMp4Builder.build(DefaultMp4Builder.java:127)

[sannies]

Oh my, there was a second one. Could you please grab the master branch and
build it on your own. I removed this second List.sort that caused you to
trip but there might be more. I don't have the time to build a new release
right now or do a thorough review.

Thank you!

Ok, thank you. I will try to build it.

[m-o]

Hi, I made build but it gives me error on all files:

I do not know, if I made some mistake when building the .jar.
I will be off the internet for few days, so I will be back to this issue after weekend.

Hi, I am still getting this error. I dot know, what I am doing wrong. Could you please create build off current version? Thank you!

[sannies]

Please find 1.1.4 here:
