Android引入Ijkplayer

我们先通过gradle的方式进行引入，下一节我们讲一讲如何进行编译。

 implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'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'implementation 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'

我们对ijkplayer封装成一个videoview

package com.yuanxuzhen.ijkplayerdemo;import tv.danmaku.ijk.media.player.IMediaPlayer;public abstract class VideoPlayerListener implements IMediaPlayer.OnBufferingUpdateListener, IMediaPlayer.OnCompletionListener, IMediaPlayer.OnPreparedListener, IMediaPlayer.OnInfoListener, IMediaPlayer.OnVideoSizeChangedListener, IMediaPlayer.OnErrorListener, IMediaPlayer.OnSeekCompleteListener {
}

package com.yuanxuzhen.ijkplayerdemo;import android.content.Context;

import tv.danmaku.ijk.media.player.IjkMediaPlayer;public class VideoPlayerIJK extends FrameLayout {/*** 由ijkplayer提供，用于播放视频，需要给他传入一个surfaceView*/private IMediaPlayer mMediaPlayer = null;/*** 视频文件地址*/private String mPath = "";private SurfaceView surfaceView;private VideoPlayerListener listener;private Context mContext;public VideoPlayerIJK(@NonNull Context context) {super(context);initVideoView(context);}public VideoPlayerIJK(@NonNull Context context, @Nullable AttributeSet attrs) {super(context, attrs);initVideoView(context);}public VideoPlayerIJK(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);initVideoView(context);}private void initVideoView(Context context) {mContext = context;//获取焦点，不知道有没有必要~。~setFocusable(true);}/*** 设置视频地址。* 根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，那就创建一个新的surfaceViewmPath = path;createSurfaceView();} else {//否则就直接loadmPath = path;load();}}/*** 新建一个surfaceview*/private void createSurfaceView() {//生成一个新的surface viewsurfaceView = 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*/private class LmnSurfaceCallback implements SurfaceHolder.Callback {@Overridepublic void surfaceCreated(SurfaceHolder holder) {}@Overridepublic void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {//surfaceview创建成功后，加载视频load();}@Overridepublic void surfaceDestroyed(SurfaceHolder holder) {}}/*** 加载视频*/private void load() {//每次都要重新创建IMediaPlayercreatePlayer();try {mMediaPlayer.setDataSource(mPath);} catch (IOException e) {e.printStackTrace();}//给mediaPlayer设置视图mMediaPlayer.setDisplay(surfaceView.getHolder());mMediaPlayer.prepareAsync();}/*** 创建一个新的player*/private void createPlayer() {if (mMediaPlayer != null) {mMediaPlayer.stop();mMediaPlayer.setDisplay(null);mMediaPlayer.release();}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.setOnInfoListener(listener);mMediaPlayer.setOnSeekCompleteListener(listener);mMediaPlayer.setOnBufferingUpdateListener(listener);mMediaPlayer.setOnErrorListener(listener);}}public void setListener(VideoPlayerListener listener) {this.listener = listener;if (mMediaPlayer != null) {mMediaPlayer.setOnPreparedListener(listener);}}/*** -------======--------- 下面封装了一下控制视频的方法*/public void start() {if (mMediaPlayer != null) {mMediaPlayer.start();}}public void release() {if (mMediaPlayer != null) {mMediaPlayer.reset();mMediaPlayer.release();mMediaPlayer = null;}}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 long getDuration() {if (mMediaPlayer != null) {return mMediaPlayer.getDuration();} else {return 0;}}public long getCurrentPosition() {if (mMediaPlayer != null) {return mMediaPlayer.getCurrentPosition();} else {return 0;}}public void seekTo(long l) {if (mMediaPlayer != null) {mMediaPlayer.seekTo(l);}}
}

接下来开始使用
