java - Muxing MP4和AAC(jcodec，MP4Parser)

我有一个用jcodec生成的MP4文件。

然后，我有了一个用Android的MediaCodec生成的AAC文件。

我想将它们混合在一起成为一个文件，并且由于我不想将我的Android API限制得太高，所以我选择MP4Parser。



这是我当前的代码：

H264TrackImpl h264Track = new H264TrackImpl(new FileDataSourceImpl("input.mp4"));
AACTrackImpl aacTrack = new AACTrackImpl(new FileDataSourceImpl("input.aac"));

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

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

FileOutputStream fileOutputStream = new FileOutputStream(new File("output.mp4"));
FileChannel fc = fileOutputStream.getChannel();
mp4file.writeContainer(fc);
fileOutputStream.close();

代码在以下行崩溃：

H264TrackImpl h264Track = new H264TrackImpl(new FileDataSourceImpl("input.mp4"));

以此作为堆栈跟踪：

（崩溃发生在this function at this line中。）



所以我不太确定那是什么意思？ jcodec是否输出与MP4Parser不兼容的MP4文件（可在所有视频播放器中使用）？

我应该寻找什么来解决这个问题？

感谢任何建议。



编辑

用错误的方式去做，这可行

Movie movie = MovieCreator.build(_videoFile.getAbsolutePath());

AACTrackImpl aacTrack = new AACTrackImpl(new FileDataSourceImpl(_aacFile));
CroppedTrack aacCroppedTrack = new CroppedTrack(aacTrack, 1, aacTrack.getSamples().size());
movie.addTrack(aacCroppedTrack);

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

FileOutputStream fileOutputStream = new FileOutputStream(_outputFile);
FileChannel fc = fileOutputStream.getChannel();
mp4file.writeContainer(fc);
fileOutputStream.close();

最佳答案

这对我有用...

        DataSource videoFile = new FileDataSourceImpl(filePath);

        Movie sor = MovieCreator.build(videoFile);

        List<Track> videoTracks = sor.getTracks();
        Track h264Track = null;

        for (Track t : videoTracks
             ) {
            if(t.getHandler().contains("vid"))
            {
                h264Track = t;
