java.lang.IndexOutOfBoundsException: index=0, limit=0

[viacheslavokolitiy]

Hi guys. I downloaded latest version of your library from maven central as gradle dependency. I trying to merge multiple videos into one, and got an exception from library My code

try {
                Movie movie = new Movie();
                Log.e("PATH", Integer.toString(filePaths.size()));
                for(String path : filePaths) {
                    Log.e("PATH", path);
                    H264TrackImpl track = new H264TrackImpl(new FileDataSourceImpl(path));
                    movie.addTrack(track);

                }
                Container out = new DefaultMp4Builder().build(movie);
                FileOutputStream fos = new FileOutputStream(new File("h264_output.mp4"));
                FileChannel fc = fos.getChannel();
                out.writeContainer(fc);
                fos.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

And got exception:

This is my code to combine audio and video. Could this issue be due to the encoding of my video file ? Any pointers would be helpful.

        H264TrackImpl h264Track = new H264TrackImpl(new MemoryDataSourceImpl(videoData));

        FileChannel fc = new FileOutputStream(new File(resultFile)).getChannel();
        mp4file.writeContainer(fc);

[sannies]

Encoding could be an issue. But it's not very likely in my eyes. Did you compile my code on your own? If yes: Did you use the aspectJ compiler to add the aspects?

I didn't compile the code. I included it as a maven dependency. Reg. the origin of my video source, I used the below command on a mp4 video i had and i used that as input to the above code. Any pointers would be helpful to resolve this issue.

ffmpeg -i video.mp4 -c:a copy -c:v libx264 -profile:v baseline -level 1 video.mp4

[sannies]

Hmm - ok, then it's definitively the video. I don't want to chase ghosts - so please send me an example file! My ffmpeg might be a different revision than your ffmpeg. I'm running ffmpeg on windows, you might run it on Mac (or linux or or or) . The input video might cause ffmpeg to produce different output as well.

This is the video.. https://www.dropbox.com/s/7uye009cuz3kuaf/darkknightnoaudio.mp4?dl=0

[sannies]

Hi Pranay, the video you sent me is already an MP4 that contains audio and video. So basically it's the result of the code you were psoting 8 hours ago. The H264TrackImpl is used to parse raw H264 Annex B stream, the AACTrackIMpl is used for raw AAC streams. Use MovieCreator to create a Movie object from the MP4 and then select the video track by calling getTracks().get(0) if you have a video-only MP4 file!

I'm not 100% sure what you are trying to do!

[svpranay]

Thank you so much for helping me out. I'll correct my code.

I'm just trying to merge a given video file (after removing the original audio) and add my custom audio to it.

[uditkumawat]

Hello sir, I am using MP4Parser for my project.I have one video file (audio+video) in .mp4 format and another audio file in .mp3 format . I have to merge two files (.mp4 and .mp3)such that audio of that video file should be muted and new audio should be there in place of that. Please help in this issue....I will be very thankful to you...

[uditkumawat]

Sir can't we use .mp3 file directly for audio merging

[sannies]

Mp3 in MP4 containers doesn't work very well. Please try to use AAC instead. What is your actual problem. What did you already try?

Hi, MP3 in MP4 containers is not working well. Don't do it is my advice. You might want to send the mp3 through Android's MediaCodec to get an AAC. Grüße, Sebastian

Hi! I need to merge video (mp4) and audio (aac), into 1 file (mp4). I did like this:

    public boolean mux(String videoFile, String audioFile, String outputFile) throws IOException {
    H264TrackImpl h264Track = new H264TrackImpl(new FileDataSourceImpl(videoFile));
    AACTrackImpl aacTrack = new AACTrackImpl(new FileDataSourceImpl(audioFile));

    Movie movie = new Movie();
    movie.addTrack(h264Track);
    movie.addTrack(aacTrack);

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

    FileChannel fc = new FileOutputStream(new File(outputFile)).getChannel();
    mp4file.writeContainer(fc);
    fc.close();

    return true;

where videoFile, audioFile and outputFile are paths like "/storage/emulated/0/DCIM/derzkayaaac.aac" etc. my multimedia files: http://dropmefiles.com/JTQlh

I got an error during execution : Caused by: java.lang.IndexOutOfBoundsException: index=0, limit=0 at java.nio.Buffer.checkIndex(Buffer.java:150) at java.nio.DirectByteBuffer.get(DirectByteBuffer.java:171) at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.readSamples(H264TrackImpl.java:297) at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.parse(H264TrackImpl.java:108) at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.(H264TrackImpl.java:90) at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.(H264TrackImpl.java:96) at com.googlecode.mp4parser.authoring.tracks.H264TrackImpl.(H264TrackImpl.java:100) at com.dev.illiakaliuzhnyi.derzkaya.Mp4ParserAudioMuxer.mux(Mp4ParserAudioMuxer.java:33) please help me out!

[sannies]

Hi, the H264TrackImpl is used to read raw h264 files. If the h264 is already in a MP4 container you should use the MovieCreator class to build a Movie object.You can then add the AACTrackImpl to the existing tracks and write the result to disk. BR, Sebastian

[amit-bst]

can you show it with an example ? actually i am also facing the same issue with same code, i understand that H264TrackImpl requires .h264 file format and we have mp4, still i am unable to figure out how can i remove the earlier audio from mp4 and then add my own mp3 or aac audio to that video.

[sannies]

Movie originalAudioAndVideo = MovieCreator.build("videoAndAudio.mp4"); Track nuAudio = new AACTrackImpl( new FileDataSourceImpl("nuAudio.aac"));

List<Track> nuTracks = new ArrayList<Track>();

for (Track track : originalAudioAndVideo.getTracks() ) { if (track.getHandler().equals("vide")) { nuTracks.add(track); } } nuTracks.add(nuAudio);

Movie nuMovie = new Movie(); nuMovie.setTracks(nuTracks);

FragmentedMp4Builder mp4builder = new FragmentedMp4Builder(); Container c = mp4builder.build(nuMovie); c.writeContainer(Channels.newChannel(new FileOutputStream("out.mp4")));

Thanks sannies, I tried this sample with the following files but the out video is not functional it sticks sometimes and no sound is there in this video. Here is the link to file https://www.dropbox.com/sh/n7r8jn7lfxf4zzw/AADpthlihBc630x61NimejoEa?dl=0

Hi, I am merging mp3 into mp4. It works fine on small length mp3 like 10 seconds, 20 seconds but when length exceeded like 53 seconds or 1:03 seconds, it gives IndexOutOfBound Exception. I think its on get(location). Can you please provide me the solution. Track audioTrack = audio.getTracks().get(0); video.addTrack(audioTrack);

[sannies]

So there is a list of tracks and when you try to access the first element you get an IndexOutOfBoundsException. What does that tell you? Perhaps that the list doesn't contain any element?

@sannies I tried to follow your instructions in the comment from August 13, 2015. But I get an NoSuchMethod error at this line: Movie originalAudioAndVideo = MovieCreator.build("videoAndAudio.mp4");

[GauravCreed]

`String outputVideo = new File(Utils.getDefaultStorage(AudioStatusActivity.this), "video" + new Random().nextInt() + ".mp4").getAbsolutePath(); String pathtoVideo = new File(Utils.getDefaultStorage(AudioStatusActivity.this) + "/" + "Videos" + "/" + "ffaec7.mp4").getAbsolutePath();

Movie originalAudioAndVideo = MovieCreator.build(pathtoVideo); Track nuAudio = new AACTrackImpl( new FileDataSourceImpl(newAudioPath)); List nuTracks = new ArrayList();

for (Track track : originalAudioAndVideo.getTracks() ) { if (track.getHandler().equals("vide")) { nuTracks.add(track); } } nuTracks.add(nuAudio);

Movie nuMovie = new Movie(); nuMovie.setTracks(nuTracks);

FragmentedMp4Builder mp4builder = new FragmentedMp4Builder(); Container c = mp4builder.build(nuMovie); c.writeContainer(Channels.newChannel(new FileOutputStream(outputVideo)));`

still not working....

[talesbarretoss]

Same issue here

[hauptkonto]

Hi. I'm having the same issue. While trying to convert from h264 to mp4 I get the IndexOutOfBoundsException. I know it does have something to do with the file and it's encoding, but still, ffmpeg is able to converti it succesfully (throwing some errors along the way). Is there a chance I can provide an h264 file so that you can take a look at it? Thanks in advance.

Best regards
