MyPLVideoTextureViewDemo
这是一个自己学习android视频播放的demo。
基于PLDroidPlayer.
使用PLDroidPlayer的PLVideoTextureView
包含功能：
- 支持屏幕右边手势上滑 --加大音量
- 支持屏幕左边手势上滑 --加大亮度
- 缓冲
- 根据尺寸自动转换横屏
- 双击放大
PLDroidPlayer
PLDroidPlayer 是一个适用于 Android 平台的音视频播放器 SDK，可高度定制化和二次开发，为 Android 开发者提供了简单、快捷的接口，帮助开发者在 Android 平台上快速开发播放器应用。
PLDroidPlayer目前基于ijkplayer, 感谢 ijkplayer ，相应的修改详见：https://github.com/pili-engineering/ijkplayer

用法
1. sdk集成
首先，下载最新版本的
PLDroidPlayer SDK
2. 导入 SDK
3. 添加依赖
compile files('libs/pldroid-player-1.3.1.jar')
compile 'com.qiniu:happy-dns:0.2.+'
compile 'com.qiniu.pili:pili-android-qos:0.8.+'
4. 添加权限
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
5. 布局
<com.pili.pldroid.player.widget.PLVideoTextureView
android:id="@+id/videoView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"/>
6. 播放器设置（需要用到sdk中demo里的MediaController）
6.1 初始化
mVideoView = (PLVideoTextureView) findViewById(R.id.videoView);
6.2 设置加载动画
mLoadingView = (ProgressBar) findViewById(R.id.LoadingView);
mVideoView.setBufferingIndicator(mLoadingView);
6.3 音量与亮度的初始化
mVolumeBrightnessLayout = findViewById(R.id.operation_volume_brightness);
mOperationBg = (ImageView) findViewById(R.id.operation_bg);
mOperationPercent = (ImageView) findViewById(R.id.operation_percent);
6.4 获取最大音量
mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
mMaxVolume = mAudioManager
.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
6.5 初始化手势识别器
mGestureDetector = new GestureDetector(this, new VideoActivity.MyGestureListener());
6.6 播放参数配置
AVOptions options = new AVOptions();
// the unit of timeout is ms
// 准备超时时间，包括创建资源、建立连接、请求码流等，单位是 ms
// 默认值是：无
options.setInteger(AVOptions.KEY_PREPARE_TIMEOUT, 10 * 1000);
options.setInteger(AVOptions.KEY_GET_AV_FRAME_TIMEOUT, 10 * 1000);
// Some optimization with buffering mechanism when be set to 1
// 解码方式，codec＝1，硬解; codec=0, 软解
// 默认值是：0
int isLiveStreaming =IS_LIVE_STREAMING;
options.setInteger(AVOptions.KEY_LIVE_STREAMING, isLiveStreaming);
// 当前播放的是否为在线直播，如果是，则底层会有一些播放优化
// 默认值是：0
if (isLiveStreaming == 1) {
// 是否开启"延时优化"，只在在线直播流中有效
// 默认值是：0
options.setInteger(AVOptions.KEY_DELAY_OPTIMIZATION, 1);
}
// 1 -> hw codec enable, 0 -> disable [recommended]
// int codec = getIntent().getIntExtra("mediaCodec", 0);
int codec = MEDIA_CODEC;
// 解码方式，codec＝1，硬解; codec=0, 软解
// 默认值是：0
options.setInteger(AVOptions.KEY_MEDIACODEC, codec);
// whether start play automatically after prepared, default value is 1
options.setInteger(AVOptions.KEY_START_ON_PREPARED, 0);
mVideoView.setAVOptions(options);
6.7 关联播放控制器
// You can also use a custom `MediaController` widget
mMediaController = new MediaController(this, false, isLiveStreaming == 1);
mVideoView.setMediaController(mMediaController);
6.8 设置播放监听
mVideoView.setOnInfoListener(mOnInfoListener);
// mVideoView.setOnVideoSizeChangedListener(mOnVideoSizeChangedListener);
mVideoView.setOnBufferingUpdateListener(mOnBufferingUpdateListener);
mVideoView.setOnCompletionListener(mOnCompletionListener);
mVideoView.setOnSeekCompleteListener(mOnSeekCompleteListener);
mVideoView.setOnErrorListener(mOnErrorListener);
mVideoView.setVideoPath(mVideoPath);
mVideoView.setDisplayAspectRatio(mDisplayAspectRatio);
mVideoView.setOnPreparedListener(mOnPreparedListener);
6.9 根据尺寸旋转方向监听
mVideoView.setOnVideoSizeChangedListener(new PLMediaPlayer.OnVideoSizeChangedListener() {
@Override
public void onVideoSizeChanged(PLMediaPlayer plMediaPlayer, int width, int height) {
// Logger.i("width:" + width + "---heightL:" + height);
System.out.println("width:" + width + "---heightL:" + height);
if (width > height&&mVideoRotation==0) {
//旋转方向
System.out.println("旋转方向");
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
//如果视频角度是90度
if(mVideoRotation==90)
{
//旋转视频
System.out.println("旋转方向" + mVideoRotation);
mVideoView.setDisplayOrientation(270);
}
}
});
6.10 开启播放器
mVideoView.setVideoPath(mVideoPath);
mVideoView.start();
7. 播放器监听实现
7.1 旋转角度
public void onClickRotate(View v) {
mRotation = (mRotation + 90) % 360;
mVideoView.setDisplayOrientation(mRotation);
}
7.2 缓冲设置
private PLMediaPlayer.OnInfoListener mOnInfoListener = new PLMediaPlayer.OnInfoListener() {
@Override
public boolean onInfo(PLMediaPlayer plMediaPlayer, int what, int extra) {
switch (what) {
case PLMediaPlayer.MEDIA_INFO_BUFFERING_START:
System.out.println("正在缓冲----\"");
//开始缓存，暂停播放
if (mVideoView != null) {
mVideoView.pause();
}
needResume = true;
mLoadingView.setVisibility(View.VISIBLE);
break;
case PLMediaPlayer.MEDIA_INFO_BUFFERING_END:
case PLMediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START:
System.out.println("缓冲完成----");
//缓存完成，继续播放
if (needResume)
if (mVideoView != null) {
mVideoView.start();
}
mLoadingView.setVisibility(View.GONE);
break;
case PLMediaPlayer.MEDIA_INFO_BUFFERING_BYTES_UPDATE:
//显示 下载速度
System.out.println("download rate:" + extra);
//mListener.onDownloadRateChanged(arg2);
break;
case 10001:
//保存视频角度
mVideoRotation=extra;
break;
}
System.out.println("onInfo:" + what + "___" + extra);
return false;
}
}
7.3 手势监听实现
private class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
/** 双击 */
@Override
public boolean onDoubleTap(MotionEvent e) {
if(mDisplayAspectRatio == PLVideoTextureView.ASPECT_RATIO_FIT_PARENT){
mDisplayAspectRatio = PLVideoTextureView.ASPECT_RATIO_PAVED_PARENT;
}else {
mDisplayAspectRatio = PLVideoTextureView.ASPECT_RATIO_FIT_PARENT;
}
if (mVideoView != null) mVideoView.setDisplayAspectRatio(mDisplayAspectRatio);
return true;
}
/** 滑动 */
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2,
float distanceX, float distanceY) {
float mOldX = e1.getX(), mOldY = e1.getY();
int y = (int) e2.getRawY();
Display disp = getWindowManager().getDefaultDisplay();
int windowWidth = disp.getWidth();
int windowHeight = disp.getHeight();
if (mOldX > windowWidth * 4.0 / 5)// 右边滑动
onVolumeSlide((mOldY - y) / windowHeight);
else if (mOldX < windowWidth / 5.0)// 左边滑动
onBrightnessSlide((mOldY - y) / windowHeight);
return super.onScroll(e1, e2, distanceX, distanceY);
}
}
7.4 改变声音大小
private void onVolumeSlide(float percent) {
if (mVolume == -1) {
mVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
if (mVolume < 0)
mVolume = 0;
// 显示
mOperationBg.setImageResource(R.drawable.video_volumn_bg);
mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
}
int index = (int) (percent * mMaxVolume) + mVolume;
if (index > mMaxVolume)
index = mMaxVolume;
else if (index < 0)
index = 0;
// 变更声音
mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, index, 0);
// 变更进度条
ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
lp.width = findViewById(R.id.operation_full).getLayoutParams().width
* index / mMaxVolume;
mOperationPercent.setLayoutParams(lp);
}
7.5 滑动改变亮度
private void onBrightnessSlide(float percent) {
if (mBrightness < 0) {
mBrightness = getWindow().getAttributes().screenBrightness;
if (mBrightness <= 0.00f)
mBrightness = 0.50f;
if (mBrightness < 0.01f)
mBrightness = 0.01f;
// 显示
mOperationBg.setImageResource(R.drawable.video_brightness_bg);
mVolumeBrightnessLayout.setVisibility(View.VISIBLE);
}
WindowManager.LayoutParams lpa = getWindow().getAttributes();
lpa.screenBrightness = mBrightness + percent;
if (lpa.screenBrightness > 1.0f)
lpa.screenBrightness = 1.0f;
else if (lpa.screenBrightness < 0.01f)
lpa.screenBrightness = 0.01f;
getWindow().setAttributes(lpa);
ViewGroup.LayoutParams lp = mOperationPercent.getLayoutParams();
lp.width = (int) (findViewById(R.id.operation_full).getLayoutParams().width * lpa.screenBrightness);
mOperationPercent.setLayoutParams(lp);
}
总结
这是自己在学习android视频播放的一个demo，只是基本使用，其中还有许多缺陷。
