我正在开发一个应用程序来使用 mp4parser 合并 n 个视频。要合并的视频是在前置摄像头和后置摄像头中拍摄的。如果我将这些视频合并为单个，则可以很好地合并所有视频，但是通过前置摄像头拍摄的替代视频将合并为倒置。我能做什么。请任何人帮助我。

这是我合并视频的代码：

try {


String f1,f2,f3;


f1 = Environment.getExternalStorageDirectory() + "/DCIM/testvideo1.mp4";// video took via back camera


f2 = Environment.getExternalStorageDirectory() + "/DCIM/testvideo2.mp4";// video took via front camera


f3 = Environment.getExternalStorageDirectory() + "/DCIM/testvideo3.mp4";// video took via front camera


        Movie[] inMovies = new Movie[] {
          MovieCreator.build(f1),
          MovieCreator.build(f2),
          MovieCreator.build(f3) 
         };
            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")) { …
