java - 复用 MP4 和 AAC(jcodec、MP4Parser)

Question

我有一个使用 jcodec 生成的 MP4 文件。

然后我就有了一个使用 Android 的 MediaCodec 生成的 AAC 文件。

我想将它们混合到一个文件中，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();

<小时/>

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。)

所以我不太确定这意味着什么？ jcodec 输出的 MP4 文件(顺便说一句，它适用于所有视频播放器)是否与 MP4Parser 不兼容？

我应该考虑什么来解决这个问题？

感谢任何建议。

编辑

以前的方法是错误的，但这个方法有效

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();

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;
