大家好我想尝试使用mp4parser在Android中附加两个视频,但问题是结果视频的持续时间为00:00,尽管它占用视频1 +视频2的大小视频都是从同一手机的同一后凸轮捕获,具有完全相同的编码,因此encoding没有任何问题。我已经看过mp4parser官方网站提到的样本,它的代码几乎相同,但似乎有其他事先谢谢 这是我的代码

private void appendVideos() throws IOException
    {
        String f1 = Environment.getExternalStorageDirectory() + "/video1.mp4";
        String f2 = Environment.getExternalStorageDirectory()+ "/video2.mp4";

        Movie[] inMovies;

        inMovies = new Movie[]
                {
                MovieCreator.build(f1),
                MovieCreator.build(f2),
                };


        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()])));
        }

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

        RandomAccessFile ram = new RandomAccessFile(String.format(Environment.getExternalStorageDirectory() + "/output.mp4"), "rw");
        FileChannel fc = ram.getChannel();
        out.writeContainer(fc);
        ram.close();
        fc.close();
        Toast.makeText(getApplicationContext(), "success", Toast.LENGTH_SHORT).show();
    }

它与我合作。

只需执行此操作即可更改您的代码。

将isoparser-1.0-RC-37.jar替换为lib文件夹中的isoparser-1.0-RC-27.jar。

从下面的链接下载isoparser-1.0-RC-27.jar文件。 http://grepcode.com/snapshot/repo1.maven.org/maven2/com.googlecode.mp4parser/isoparser/1.0-RC-27
