各种视频播放功能的总结
1.直接上效果图
2.使用VideoView加载视频
private void playVideo() {
// //2、使用VideoView来播放。在布局文件中使用VideoView结合MediaController来实现对其控制。
// //6.0要手动添加权限
// myVideoView.setMediaController(new MediaController(this));//添加进度条
// myVideoView.setVideoURI(uri);
// myVideoView.start();
// myVideoView.requestFocus();
try {
MediaMetadataRetriever media = new MediaMetadataRetriever();
if (Build.VERSION.SDK_INT >= 14) {
media.setDataSource(videopath, new HashMap<String, String>());
} else {
media.setDataSource(videopath);
}
//获取第一帧
bitmap = media.getFrameAtTime(1, MediaMetadataRetriever.OPTION_CLOSEST_SYNC);
imageView.setImageBitmap(bitmap);
media.release();
// Glide.with(getApplicationContext())
// .load(videopath)
// .into(imageView);
//视频循环播放
//myVideoView.setVideoURI(uri);
myVideoView.setVideoPath(videopath);
myVideoView.start();//播放
// myVideoView.pause();//暂停、播放
MediaController mediaController = new MediaController(this);
// mediaController.onFinishInflate();//一进来时显示进度条
myVideoView.setMediaController(mediaController);//添加进度条
//注册在媒体文件加载完毕，可以播放时调用的回调函数。可循环播放视频
myVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
// mp.start();//离开界面还回后可以重新播放
mp.setLooping(true);//设置是否对播放的东东进行循环播放。
mp.setOnInfoListener(new MediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(MediaPlayer mediaPlayer, int what, int i1) {
//开始播放时，就把显示第一帧的ImageView gone 掉
if (what == MediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START) {
// video started; hide the placeholder.
imageView.setVisibility(View.GONE);
//videoView.seekTo(0);
return true;
}
Log.e("aaa", "00000000000000");
return false;
}
});
}
});
//
// //注册在媒体文件播放完毕时调用的回调函数。可设置循环播放视频
// myVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
// @Override
// public void onCompletion(MediaPlayer mp) {
// //myVideoView.setVideoURI(uri);
// myVideoView.setVideoPath(videopath);
// myVideoView.start();
// //mp.start();//这里设置该值，离开界面还回后不会重新播放
// }
// });
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "可能视频地址有问题", Toast.LENGTH_SHORT).show();
}
}
3.MediaPlayer+SurfaceView播放视频
public void play() {
String path = "http://192.168.88.149:999/images/IC/IC0000054/IC0000054_180420163814230_iOS.mp4";
try {
mMediaPlayer.reset();
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
//设置需要播放的视频
mMediaPlayer.setDataSource(this, Uri.parse(path));
mMediaPlayer.setLooping(true);//循环播放
//把视频画面输出到SurfaceView
mMediaPlayer.setDisplay(mSurfaceView.getHolder());
mMediaPlayer.prepare();//将资源同步缓存到内存中,一般加载本地较小的资源可以用这个
// mMediaPlayer.prepareAsync();//较大的资源或者网络资源建议使用prepareAsync方法,异步加载
mMediaPlayer.start();
} catch (IOException e) {
e.printStackTrace();
}
}
4.MediaPlayer+TextureView播放视频
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_texture_view);
setTitle("MediaPlayer+TextureView");
TextureView textureView = findViewById(R.id.textureView);
textureView.setSurfaceTextureListener(surfaceTezxtureListener);//设置监听函数 重写4个方法
videoImage = findViewById(R.id.videoImage);
seekBar = findViewById(R.id.seekBar);
seekBar.setOnSeekBarChangeListener(onSeekBarChangeListener);//seekbar改变监听
}
private SeekBar.OnSeekBarChangeListener onSeekBarChangeListener = new SeekBar.OnSeekBarChangeListener() {
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {//进度改变
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {//开始拖动seekbar
}
@Override
public void onStopTrackingTouch(SeekBar seekBar) {//停止拖动seekbar
if (mMediaPlayer != null && mMediaPlayer.isPlaying())//播放中
mMediaPlayer.seekTo(seekBar.getProgress());
}
};
private TextureView.SurfaceTextureListener surfaceTezxtureListener = new TextureView.SurfaceTextureListener() {
@Override
public void onSurfaceTextureAvailable(SurfaceTexture surfaces, int width, int height) {
surface = new Surface(surfaces);
new PlayerVideoThread().start();//开启一个线程去播放视频
}
@Override
public void onSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height) {//尺寸改变
}
@Override
public boolean onSurfaceTextureDestroyed(SurfaceTexture surfaces) {//销毁
surface = null;
mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = null;
return true;
}
@Override
public void onSurfaceTextureUpdated(SurfaceTexture surface) {//更新
}
};
private class PlayerVideoThread extends Thread {
@Override
public void run() {
try {
mMediaPlayer = new MediaPlayer();
Uri uri = Uri.parse("http://192.168.88.149:999/images/IC/IC0000054/IC0000054_180420163814230_iOS.mp4");
mMediaPlayer.setDataSource(TextureViewActivity.this, uri);//设置播放资源(可以是应用的资源文件／url／sdcard路径)
mMediaPlayer.setSurface(surface);//设置渲染画板
mMediaPlayer.setLooping(true);//循环播放
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);//设置播放类型
// mMediaPlayer.setOnCompletionListener(onCompletionListener);//播放完成监听,有循环播放不会有此监听
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {//预加载监听
@Override
public void onPrepared(MediaPlayer mp) {
videoImage.setVisibility(View.GONE);
mMediaPlayer.start();//开始播放
seekBar.setMax(mMediaPlayer.getDuration());//设置总进度
handler.post(mTicker);//更新进度
}
});
mMediaPlayer.prepare();
} catch (Exception e) {
e.printStackTrace();
}
}
}
private MediaPlayer.OnCompletionListener onCompletionListener = new MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {//播放完成
videoImage.setVisibility(View.VISIBLE);
seekBar.setProgress(0);
handler.removeCallbacks(mTicker);//删除执行的Runnable 终止计时器
}
};
5.使用第三方播放器（饺子播放器）
private String path = "http://192.168.88.149:999/images/IC/IC0000054/IC0000054_180420163814230_iOS.mp4";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_jiao_zi_video_player);
MyJZVideoPlayerStandard myJZVideoPlayerStandard = findViewById(R.id.jz_video);
MediaMetadataRetriever media = new MediaMetadataRetriever();
if (Build.VERSION.SDK_INT >= 14) {
media.setDataSource(path, new HashMap<String, String>());
} else {
media.setDataSource(path);
}
//获取第一帧
Bitmap bitmap = media.getFrameAtTime(1, MediaMetadataRetriever.OPTION_CLOSEST_SYNC);
media.release();
//用于Glide可以加载Bitmap图片
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] bytes = baos.toByteArray();
myJZVideoPlayerStandard.setUp(path, JZVideoPlayerStandard.SCREEN_WINDOW_NORMAL, "视频播放");
// Glide.with(this).load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png").into(myJZVideoPlayerStandard.thumbImageView);
Glide.with(this).load(bytes).into(myJZVideoPlayerStandard.thumbImageView);
// JZVideoPlayer.setJzUserAction(null);
}
public void jumpToText(View v) {
startActivity(new Intent(this, TextActivity.class));
}
6.视频下载
/**
* 检查并下载视频资源
*/
public void downLoadVideo(View v) {
File file = new File(path);
Log.e("TAG", "===>" + path);
//文件夹不存在，则创建它
if (!file.exists()) {
file.mkdir();
}
FileDownloader.setup(this);
FileDownloader.getImpl().create(videoUrl)
.setPath(path + "/" + videoName)
.setForceReDownload(false)//强制重新下载，将会忽略检测文件是否健在
.setListener(new FileDownloadListener() {
@Override
protected void pending(BaseDownloadTask task, int soFarBytes, int totalBytes) {
//等待，已经进入下载队列
Log.e("TAG", "pending");
}
@Override
protected void progress(BaseDownloadTask task, int soFarBytes, int totalBytes) {
//下载进度
Log.e("TAG", "--" + i++);
}
@Override
protected void retry(final BaseDownloadTask task, final Throwable ex, final int retryingTimes, final int soFarBytes) {
Log.e("TAG", "retry");
}
@Override
protected void completed(BaseDownloadTask task) {
//完成整个下载过程
i = 0;
}
@Override
protected void paused(BaseDownloadTask task, int soFarBytes, int totalBytes) {
//暂停下载
Log.e("TAG", "paused");
}
@Override
protected void error(BaseDownloadTask task, Throwable e) {
//下载出现错误
Log.e("TAG", "error===>" + e.getMessage());
}
@Override
protected void warn(BaseDownloadTask task) {
//在下载队列中(正在等待/正在下载)已经存在相同下载连接与相同存储路径的任务
Log.e("TAG", "warn");
}
}).start();
}
