java - 代号一限制用户只能录制3秒视频

Question

我需要代号为一的用户录制的视频，我已经完成了。但我想限制用户录制长度不超过 3 秒的视频。

有什么方法可以在录制后剪切视频或者可以在3秒后停止录制吗？

Answer 1

我在另一个帖子上发现了这个，还没有经验，但这可能对你有帮助。

Media = MediaManager.createMediaRecorder("filename.xyz", MediaManager.getMediaRecorderingMimeType());
Button doneButton = new Button("DONE");

doneButton.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent evt) {
            stopRecord(false);
        }
    });

   public void stopRecord(boolean timeElapsed)
   {
       answertiming.cancel();
       media.pause();
       media.cleanup();
       if(timeElapsed)
            Dialog.show("SUCCESS","Your time is up system has saved your answer, The file path for the recording is " + p, "OK",null);
       else
            Dialog.show("SUCCESS","You have successfully answered the question System has saved your answer, The file path for the recording is " + p, "OK",null);
   }

我现在的方法是在这个时间前后加入一个 3 秒的计时器

UITimer timer = new UITimer(new Runnable() {
            @Override
            public void run() {
                 stopreRecord(true);
});
timer.schedule(3000, false, f);
