Android 视频播放器第三方框架之ijkplayer
一：介绍
ijkplayer是b站开源的超级好用的视频播放器喔，置信大家都早有耳闻。ijkplayer Android和ios都可用，还反对多种视频的硬解码
二：应用
第一步：增加依赖
dependencies {
//个别这2个曾经足够用了，这是增加了一个armv7a的cpu架构，反对armv7a和arm64笼罩了大部分手机
//required, enough for most devices.
implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'
implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'
// Other ABIs: optional
//这里x86 x86_64针对平板和模拟器
implementation 'tv.danmaku.ijk.media:ijkplayer-armv5:0.8.8'
implementation 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'
implementation 'tv.danmaku.ijk.media:ijkplayer-x86:0.8.8'
implementation 'tv.danmaku.ijk.media:ijkplayer-x86_64:0.8.8'
//ExoPlayer as IMediaPlayer: optional, experimental
implementation 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'
}
第二步：增加3个so库
看到咱们是在libs下配置的·so库
须要app在build.gradle下
android{
defaultConfig{
ndk {
//抉择要增加的对应cpu类型的.so库。,打包编译只会减轻一个armeabi-v7a，so库
abiFilters 'armeabi-v7a'
}
}
//应为在libs下配置的须要定位到，如果是在src/main创立jniLibs文件夹就须要上面
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
}
三个so库libijkffmpeg.so封装解码的应用，libijkplayer.so视频播放的，libijksdl.so
第三步：创立一个View
public class MyIjkVideoView extends FrameLayout {
private Context mContext;//上下文
private IMediaPlayer mMediaPlayer = null;//视屏播放
private TextView subtitleDisplay;//字幕View
private SurfaceView surfaceView;//视图次要实用于被动更新，例如频繁地刷新
private VideoPlayerListener listener;//jiant
/**
* 视频文件地址
*/
private String mPath = "";
private boolean mEnableBackgroundPlay = false;//是否开启后盾服务
public MyIjkVideoView(@NonNull Context context) {
super(context);
initVideoView(context);
}
public MyIjkVideoView(@NonNull Context context, @Nullable AttributeSet attrs) {
super(context, attrs);
initVideoView(context);
}
public MyIjkVideoView(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initVideoView(context);
}
/**
* 初始化VideoView
*/
private void initVideoView(Context context) {
mContext = context;
//是否开启后盾播放，如果开启了后盾播放，就启动一个Service来做后盾播放。
initBackground();
//初始化渲染器，创立SurfaceView或TextureView，并addView()。（IjkVideoView是FrameLayout）
initRenders();
//焦点
setFocusable(true);
setFocusableInTouchMode(true);
requestFocus();
//字幕View
subtitleDisplay = new TextView(context);
subtitleDisplay.setTextSize(24);
subtitleDisplay.setGravity(Gravity.CENTER);
FrameLayout.LayoutParams layoutParams_txt = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT,
FrameLayout.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM);
addView(subtitleDisplay, layoutParams_txt);
}
private void initRenders() {
}
private void initBackground() {
//这里相当于没有进去，具体须要再解决
if (mEnableBackgroundPlay) {
MediaPlayerService.intentToStart(getContext());
mMediaPlayer = MediaPlayerService.getMediaPlayer();
}
}
/**
* 设置视频地址。
* 依据是否第一次播放视频，做不同的操作。
*
* @param path the path of the video.
*/
public void setVideoPath(String path) {
if (TextUtils.equals("", mPath)) {
//如果是第一次播放视频，那就创立一个新的surfaceView
mPath = path;
createSurfaceView();
} else {
//否则就间接load
mPath = path;
load();
}
}
/**
* 新建一个SurfaceView
*/
private void createSurfaceView() {
//生成一个新的surface view
surfaceView = new SurfaceView(mContext);
surfaceView.getHolder().addCallback(new LmnSurfaceCallback());
LayoutParams layoutParams = new LayoutParams(LayoutParams.MATCH_PARENT
, LayoutParams.MATCH_PARENT, Gravity.CENTER);
surfaceView.setLayoutParams(layoutParams);
this.addView(surfaceView);
}
/**
* surfaceView的监听器,外部类
*/
private class LmnSurfaceCallback implements SurfaceHolder.Callback {
@Override
public void surfaceCreated(@NonNull SurfaceHolder holder) {
//在SurfaceView创立
}
@Override
public void surfaceChanged(@NonNull SurfaceHolder holder, int format, int width, int height) {
//在SurfaceView扭转,加载视屏
load();
}
@Override
public void surfaceDestroyed(@NonNull SurfaceHolder holder) {
//在SurfaceView销毁
}
}
/**
* 加载视屏
*/
private void load() {
//每次都要从新创立IMediaPlayer
createPlayer();
try {
mMediaPlayer.setDataSource(mPath);
} catch (IOException e) {
e.printStackTrace();
}
//给mediaPlayer设置视图
mMediaPlayer.setDisplay(surfaceView.getHolder());
mMediaPlayer.prepareAsync();
}
private void createPlayer() {
//去除旧的
if (mMediaPlayer != null) {
mMediaPlayer.stop();
mMediaPlayer.setDisplay(null);
mMediaPlayer.release();
}
//新建一个新的
IjkMediaPlayer ijkMediaPlayer = new IjkMediaPlayer();
ijkMediaPlayer.native_setLogLevel(IjkMediaPlayer.IJK_LOG_DEBUG);
//开启硬解码 ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "mediacodec", 1);
mMediaPlayer = ijkMediaPlayer;
if (listener != null) {
mMediaPlayer.setOnPreparedListener(listener);
mMediaPlayer.setOnErrorListener(listener);
mMediaPlayer.setOnCompletionListener(listener);
}
}
public void setListener(VideoPlayerListener listener) {
this.listener = listener;
if (mMediaPlayer != null) {
mMediaPlayer.setOnPreparedListener(listener);
}
}
public interface VideoPlayerListener extends IMediaPlayer.OnPreparedListener,
IMediaPlayer.OnCompletionListener,
IMediaPlayer.OnErrorListener {
}
/**上面配置一些暂停，开始，进行等办法*/
public boolean isPlaying() {
if (mMediaPlayer != null) {
return mMediaPlayer.isPlaying();
}
return false;
}
public void start() {
if (mMediaPlayer != null) {
mMediaPlayer.start();
}
}
public void pause() {
if (mMediaPlayer != null) {
mMediaPlayer.pause();
}
}
public void stop() {
if (mMediaPlayer != null) {
mMediaPlayer.stop();
}
}
public void reset() {
if (mMediaPlayer != null) {
mMediaPlayer.reset();
}
}
public void release() {
if (mMediaPlayer != null) {
mMediaPlayer.reset();
mMediaPlayer.release();
mMediaPlayer = null;
}
}
}
在布局中应用View
<com.ruan.mygitignore.MyIjkVideoView
android:id="@+id/ijk_video"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
第四步：调用
MyIjkVideoView ijkVideoView=findViewById(R.id.ijk_video);
String url = "https://wdl.wallstreetcn.com/41aae4d2-390a-48ff-9230-ee865552e72d";
//加载本地库
IjkMediaPlayer.loadLibrariesOnce(null);
IjkMediaPlayer.native_profileBegin("libijkplayer.so");
//监听
ijkVideoView.setListener( new MyIjkVideoView.VideoPlayerListener() {
@Override
public void onCompletion(IMediaPlayer iMediaPlayer) {
Log.d("aa","实现");
}
@Override
public boolean onError(IMediaPlayer iMediaPlayer, int i, int i1) {
Log.d("aa","失败");
return false;
}
@Override
public void onPrepared(IMediaPlayer iMediaPlayer) {
Log.d("aa","筹备");
}
});
//设置门路
ijkVideoView.setVideoPath(url);
//开始加载
ijkVideoView.start();
