Android视频播放框架Vitamio集成及使用MediaPlayer+SurfaceView、VideoView+MediaController实现播放网络视频
工作内容：
准备工作【集成Vitamio】
1.使用Vitamio框架中的VideoView,MediaController播放本地视频和网络视频
2.使用Vitamio的MediaPlayer+SurfaceView(用于得到SurfaceHolder)来播放视频
3.自定义MediaController，让其播放控制栏更好用【可以放其他的控件来控制VideoView的播放状态】
【注意：使用前需先执行vitamio的初始化操作【Vitamio.initialize(this)】】
学习分享：
使用Vitamio的原因是：Vitamio能够解析很多格式的视频（MKV，FLV，MP4，MOV，TS，RMVB,MMS, RTSP, RTMP, HLS(m3u8) 等常见的多种视频流媒体协议，包括点播与直播），而我们系统自带的VideoView仅可以播放MP4，,3GP格式的视频。
【集成Vitamio】
1.在github上下载/clone“vitamio”地址：https://github.com/yixia/VitamioBundle
2.将VitamioBundle解压后，通过new —— import Module导入vitamio文件夹【出错，修改build.gradle中的compileSdkVersion，buildToolsVersion与你常用的一致即可】导入成功。
3.将vitamio添加为你原来的app的Module依赖，完成即可使用。
一、使用Vitamio框架中的VideoView,MediaController播放本地视频和网络视频
1.java代码：
import android.net.Uri;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import java.io.File;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.Vitamio;
import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;
public class Demo_5_Activity extends AppCompatActivity {
private VideoView videoView;
private TextView tvProgress;
private TextView tvDownloadSpeed;
private String urlString = "http://112.253.22.157/17/z/z/y/u/zzyuasjwufnqerzvyxgkuigrkcatxr/hc.yinyuetai.com/D046015255134077DDB3ACA0D7E68D45.flv";
private MediaController controller;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_demo_5_);
File file = Environment.getExternalStorageDirectory();
File file1 = new File(file,"a11.mp4");
//判断Vitamio是否已经初始化【并且初始化】
if (Vitamio.initialize(this)) {
videoView = (VideoView) findViewById(R.id.vitamio);
// videoView.setVideoURI(Uri.parse(urlString));//播放网络视频
videoView.setVideoPath(file1.getPath());//播放本地视频
controller = new MediaController(this);//视频控制器
videoView.setMediaController(controller);//关联控制器
videoView.start();
}
initView();
setListener();
}
private void setListener() {
//设置缓冲进度的监听
videoView.setOnBufferingUpdateListener(new MediaPlayer.OnBufferingUpdateListener() {
@Override
public void onBufferingUpdate(MediaPlayer mp, int percent) {
tvProgress.setText(percent + "%");
}
});
//设置缓冲下载监听
videoView.setOnInfoListener(new MediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
switch (what) {
//开始缓冲
case MediaPlayer.MEDIA_INFO_BUFFERING_START://开始缓冲时的视图变化
tvProgress.setVisibility(View.VISIBLE);
tvDownloadSpeed.setVisibility(View.VISIBLE);
mp.pause();
break;
//缓冲结束
case MediaPlayer.MEDIA_INFO_BUFFERING_END://缓冲好后的视图变化（可播放）
tvProgress.setVisibility(View.GONE);
tvDownloadSpeed.setVisibility(View.GONE);
mp.start();
break;
//正在缓冲
case MediaPlayer.MEDIA_INFO_DOWNLOAD_RATE_CHANGED:
tvDownloadSpeed.setText("当前网速:" + extra + "kb/s");//下载是速度
break;
}
return true;
}
});
//设置准备监听（判断一准备好播放）
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
videoView.setBufferSize(512*1025);//设置缓冲区大小
}
});
}
private void initView() {
tvProgress = (TextView) findViewById(R.id.tv_progress_home);
tvDownloadSpeed = (TextView) findViewById(R.id.tv_download_home);
}
}
二、使用Vitamio的MediaPlayer+SurfaceView(用于得到SurfaceHolder)来播放视频
java代码：
import java.io.IOException;
import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;
import io.vov.vitamio.MediaPlayer;
import io.vov.vitamio.Vitamio;
import io.vov.vitamio.utils.Log;
import read.liu.com.videoplayer.R;
public class MediaActivity extends AppCompatActivity {
private long playTime = 0;
private MediaPlayer mediaPlayer;
private SurfaceHolder surfaceHolder;
private String urlString = "http://112.253.22.157/17/z/z/y/u/zzyuasjwufnqerzvyxgkuigrkcatxr/hc.yinyuetai.com/D046015255134077DDB3ACA0D7E68D45.flv";
private boolean isPlay = false; //用于记录是否在播放
@BindView(R.id.sf_media)
SurfaceView sfMedia;
@BindView(R.id.ib_play_media)
ImageButton ibPlayMedia;
@BindView(R.id.pb_media)
SeekBar pbMedia;
@BindView(R.id.ib_fullscreen_media)
ImageButton ibFullscreenMedia;
private int progress1 = 1;
private Uri uri;
private Handler handler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
pbMedia.setProgress(progress1);
if((playTime-progress1*1000)<=1000){
Log.e("-----------","播放结束");
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_media);
ButterKnife.bind(this);
Vitamio.initialize(this);//初始化Vitamio
init();
}
private void init() {
//关联mediaplayer和surfaceView
surfaceHolder = sfMedia.getHolder();
surfaceHolder.setFormat(PixelFormat.RGBA_8888);//设置播放的清晰度（像素格式）
mediaPlayer = new MediaPlayer(MediaActivity.this);
mediaPlayer.setLooping(false);
uri = Uri.parse(urlString);
surfaceHolder.addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceCreated(SurfaceHolder holder) {
try {
mediaPlayer.setDisplay(surfaceHolder);//关联mediaplayer和surfaceview
mediaPlayer.setDataSource(MediaActivity.this, uri);//设置播放数据源
mediaPlayer.prepareAsync();//异步准备
//异步准备监听
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
playTime = mediaPlayer.getDuration();
pbMedia.setMax((int)playTime/1000);//设置seekbar的最大值
isPlay = true;
mediaPlayer.start();
startTimeTast();
ibPlayMedia.setImageResource(read.liu.com.wait.R.drawable.ic_adjust_black_24dp);
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
});
mediaPlayer.setOnInfoListener(new MediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
switch (what) {
//开始缓冲
case MediaPlayer.MEDIA_INFO_BUFFERING_START://开始缓冲时的视图变化
mp.pause();
break;
//缓冲结束
case MediaPlayer.MEDIA_INFO_BUFFERING_END://缓冲好后的视图变化（可播放）
mp.start();
break;
//正在缓冲
case MediaPlayer.MEDIA_INFO_DOWNLOAD_RATE_CHANGED:
break;
}
return true;
}
});
//添加拖动条监听事件
pbMedia.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
//判断是用户拖动进度条产生的改变
if(fromUser){
mediaPlayer.seekTo(seekBar.getProgress()*1000);
progress1 = progress;
}
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});
}
private void startTimeTast() {
new Thread(){
@Override
public void run() {
while (isPlay){
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
handler.sendEmptyMessage(0);
progress1++;
}
}
}.start();
}
@OnClick({R.id.ib_play_media, R.id.pb_media})
public void onClick(View view) {
switch (view.getId()) {
//点击了播放/暂停按钮
case R.id.ib_play_media:
if (isPlay) {
ibPlayMedia.setImageResource(read.liu.com.wait.R.drawable.ic_adjust_black_24dp);
mediaPlayer.pause();
isPlay = false;
} else {
ibPlayMedia.setImageResource(read.liu.com.wait.R.drawable.ic_play_arrow);
mediaPlayer.start();
isPlay = true;
}
startTimeTast();
break;
case R.id.pb_media:
break;
}
}
//退出后注销mediapalyer
@Override
protected void onDestroy() {
super.onDestroy();
if (mediaPlayer != null) {
mediaPlayer.stop();
mediaPlayer.release();
}
}
@OnClick(R.id.ib_fullscreen_media)
public void onClick() {
//点击全屏按钮——将播放参数传入下一个全屏的界面
}
}
