Android VideoView的resume和seekTo

发布于 2024-09-04 19:03:14 字数 300 浏览 13 评论 0原文

我正在我的应用程序中使用 VideoView 播放视频。单击按钮后，它会记录视频的当前位置，然后应用程序会打开浏览器并显示一些网址。按下后退按钮后，应用程序将返回视频应用程序并从中断处恢复视频。

我查看了 Android Activity 生命周期，发现一旦视频 Activity 进入前台，就会调用 onStart() 方法。因此，我在 onStart() 中创建布局并通过查找当前位置来播放视频。

我的问题是，当视频恢复时，它从一开始就缓冲，然后寻找。既然它已经第一次缓冲了，有没有办法在执行seekTo时再次消除缓冲？

谢谢克里斯

我有类似的问题。我有一个 OnPreparedListener 在开始之前执行seekTo。除了视频开头出现音频故障外，seekTo 可以正常工作，就好像视频开始播放然后进行搜索一样。我不知道我的代码是否有助于解决所描述的缓冲问题，但它可能有助于阐明它。

  mVideoView.setVisibility(View.VISIBLE);
  //get current window information, and set format, set it up differently, if you need some special effects
  getWindow().setFormat(PixelFormat.TRANSLUCENT);
  //mVideoView.setVideoURI(Uri.parse(path));
  mVideoView.setVideoPath(path);
  //get focus, before playing the video.
  mVideoView.requestFocus();
  mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
           public void onPrepared(MediaPlayer mp) {                         
           mVideoView.seekTo(mImageSeek);
           mVideoView.start();
        }
     });

I am having a similar problem. I have an OnPreparedListener that does the seekTo prior to the start. The seekTo works except that there is an audio glitch that is coming from the very beginning of the video, as if it is starting to play and then seeking. I don't know if my code would help the buffering problem described but it may help illuminate it.

  mVideoView.setVisibility(View.VISIBLE);
  //get current window information, and set format, set it up differently, if you need some special effects
  getWindow().setFormat(PixelFormat.TRANSLUCENT);
  //mVideoView.setVideoURI(Uri.parse(path));
  mVideoView.setVideoPath(path);
  //get focus, before playing the video.
  mVideoView.requestFocus();
  mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
           public void onPrepared(MediaPlayer mp) {                         
           mVideoView.seekTo(mImageSeek);
           mVideoView.start();
        }
     });

代码

videoview = (VideoView) findViewById(R.id.videoview_play);
videoview.setVideoPath(dir + videoName);
//get focus, before playing the video.
videoview.setMediaController(new MediaController(this));
videoview.requestFocus();
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                                       public void onPrepared(MediaPlayer mp){                         
                                         videoview.seekTo(5000);
                                         videoview.start();
                                       }
                                });

定义您的资源视频视图，然后使用您必须添加的 .setMediaController(new MediaController(this));
希望

videoview.requestFocus();

在使用PrepareListener之前

它能帮助你

Define your Resource videoview then use this code

videoview = (VideoView) findViewById(R.id.videoview_play);
videoview.setVideoPath(dir + videoName);
//get focus, before playing the video.
videoview.setMediaController(new MediaController(this));
videoview.requestFocus();
videoview.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                                       public void onPrepared(MediaPlayer mp){                         
                                         videoview.seekTo(5000);
                                         videoview.start();
                                       }
                                });

you have to add .setMediaController(new MediaController(this));
and
