在 TextureView 上播放视频 [英] Playing video on TextureView

问题描述

在 Android TextureView 的文档中，它说你可以使用一个 TextureView 来播放视频:但我似乎无法找到如何做到这一点的任何例子.有人知道吗?

In the documentation of Android TextureView it says that you can use a TextureView to play video: But I cant seem to find any example of how to do this. Does anyone know?

我需要使用 textureView 因为我想为视频制作动画.我想播放 .3gp/.mp4 格式的视频，而不是来自相机的视频 :)

I need to use a textureView because I want to animate the video. I want to play a video in .3gp/.mp4 format, not video from the Camera :)

任何帮助将不胜感激..

Any help would be appreciated..

Public class MediaPlayerDemo_Video extends Activity implements TextureView.SurfaceTextureListener {


 private MediaPlayer mMediaPlayer;

 private TextureView mPreview;

 @Override
 public void onCreate(Bundle icicle) {

      super.onCreate(icicle);

      mPreview = new TextureView(this);
      mPreview.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
      mPreview.setSurfaceTextureListener(this);

      extras = getIntent().getExtras();

      setContentView(mPreview);
 }

 @Override
 public void onSurfaceTextureAvailable(SurfaceTexture surface, int width, int height) {
 Surface s = new Surface(surface);

 try {
       mMediaPlayer= new MediaPlayer();
       mMediaPlayer.setDataSource("http://daily3gp.com/vids/747.3gp");
       mMediaPlayer.setSurface(s);
       mMediaPlayer.prepare();
       mMediaPlayer.setOnBufferingUpdateListener(this);
       mMediaPlayer.setOnCompletionListener(this);
       mMediaPlayer.setOnPreparedListener(this);
       mMediaPlayer.setOnVideoSizeChangedListener(this);
       mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
       mMediaPlayer.start();
      } catch (IllegalArgumentException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (SecurityException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalStateException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }   
} 

动画效果非常好.
