急求： android怎么对mpg格式视频实现在线播放？？？
对于3GP格式的视频都直接可以进行播放，但是对mpg格式谈话对话框提示无法播放此视频。是不是mpg格式的还需要我特别进行格式转化呢？
播放视频使用的控件是VideoView。

public class MediaActivity extends Activity {

   public static final String TAG = "VideoPlayer";
    private VideoView mVideoView;
    private Uri mUri;
    private int mPositionWhenPaused = -1;

    private MediaController mMediaController;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_media);

        //Set the screen to landscape.
        this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        mVideoView = (VideoView)findViewById(R.id.video_view);

        //Video file
//        mUri = Uri.parse(Environment.getExternalStorageDirectory() + "/1.3gp");
//        mUri=Uri.parse("http://daily3gp.com/vids/family_guy_penis_car.3gp");
        mUri = Uri.parse("http://www.nuoter.com/qingnianjiwang.mpg");
        //Create media controller，组件可以控制视频的播放，暂停，回复，seek等操作，不需要你实现
        mMediaController = new MediaController(this);
        mVideoView.setMediaController(mMediaController);
    }

    public void onStart() {
        // Play Video
        mVideoView.setVideoURI(mUri);
        mVideoView.start();

        super.onStart();
    }

    public void onPause() {
        // Stop video when the activity is pause.
        mPositionWhenPaused = mVideoView.getCurrentPosition();
        mVideoView.stopPlayback();

        super.onPause();
    }

    public void onResume() {
        // Resume video player
        if(mPositionWhenPaused >= 0) {
            mVideoView.seekTo(mPositionWhenPaused);
            mPositionWhenPaused = -1;
        }

        super.onResume();
    }

    public boolean onError(MediaPlayer player, int arg1, int arg2) {
        return false;
    } 
 

    public void onCompletion(MediaPlayer mp) {
        this.finish();
    }
}

[解决办法]
用ffmpeg解码器加上去试试
