大家好，我正在尝试在android中附加两个视频mp4parser，但问题是生成的视频是00:00持续时间，尽管它占据了video1 + video2的大小，这两个视频都是从同一手机的同一个后置摄像头以完全相同的编码捕获的所以encoding没有任何问题。我已经查看了 mp4parser 官方网站引用的示例，它几乎是相同的代码，但似乎还有其他东西提前谢谢这里是我的代码
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();
}
