在Android中录制后，FFMpeg将文本添加到实际视频文件中

Question

使用JavaCV在Android设备中录制视频并使用视频播放进行播放。现在想要在播放时在视频上显示文本，这是在录制视频后输入的。播放视频时必须在所有视频播放器中看到此文本。

我已经通过链接How to add text on video recording?，这也是预期的

这是录制视频后调用的方法。

private void playRecordedVideo(Uri videoUri, boolean playVideoInLoop)
{
    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);

    videoView.setLayoutParams(layoutParams);

    videoView.setVisibility(View.VISIBLE);
    videoView.setVideoURI(videoUri);
    if(playVideoInLoop)
    {
        MediaController mediaController = new MediaController(MainActivity.this);
        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);
        videoView.setOnPreparedListener (new OnPreparedListener() {                    
            @Override
            public void onPrepared(MediaPlayer mp) {
                mp.setLooping(true);
            }
        });
    }
    else
    {
        videoView.setMediaController(null);
    }
    videoView.start();
    btnStart.setText(getString(R.string.txt_finish));
}
