Question

我尝试通过mp4parser lib连接两个mp4视频。但是我收到了错误。这是我的代码

public void appendTwoVideo(String mp4_1,String mp4_2) throws IOException {
    Movie[] inMovies = new Movie[]{MovieCreator.build(mp4_1),
            MovieCreator.build(mp4_2)};

    List<Track> videoTracks = new LinkedList<Track>();
    List<Track> audioTracks = new LinkedList<Track>();

    for (Movie m : inMovies) {
        for (Track t : m.getTracks()) {
            if (t.getHandler().equals("soun")) {
                audioTracks.add(t);
            }
            if (t.getHandler().equals("vide")) {
                videoTracks.add(t);
            }
        }
    }

    Movie result = new Movie();

    if (audioTracks.size() > 0) {
        result.addTrack(new AppendTrack(audioTracks.toArray(new Track[audioTracks.size()])));
    }
    if (videoTracks.size() > 0) {
        result.addTrack(new AppendTrack(videoTracks.toArray(new Track[videoTracks.size()])));
    }

    IsoFile out =  new DefaultMp4Builder().build(result);

    FileChannel fc = new RandomAccessFile(String.format("output.mp4"), "rw").getChannel();
    fc.position(0);
    out.getBox(fc);
    fc.close();
}

排队

IsoFile out =  new DefaultMp4Builder().build(result);

我收到错误

错误：（296,53）错误：不兼容的类型：容器无法转换为IsoFile。

任何人都可以帮我解决错误或者如何以其他方式连接两个视频？

我找到了解决方案

只是不要使用IsoFile。使用Container作为类型，使用

将容器写入磁盘

    WritableByteChannel wbc = new FileOutputStream(

            new File(outputDirectory, filename)).getChannel();

    try {

        container.writeContainer(wbc);

    } finally {

        wbc.close();

    }
