1.认识ijkplayer
最近公司准备开发一款视频播放及直播的应用，找了许多开源的框架，大部分都是基于ffmpeg开发的。最开始准备用Vitamio框架开发的，相关的文章也比较丰富，结果对于非个人移动应用均需购买Vitamio使用授权。不过B站开源的ijkplayer也不错，而且也不需要商业授权。
ijkplayer是一个基于FFmpeg的轻量级Android/iOS视频播放器。FFmpeg的是全球领先的多媒体框架，能够解码，编码， 转码，复用，解复用，流，过滤器和播放大部分的视频格式。它提供了录制、转换以及流化音视频的完整解决方案。它包含了非常先进的音频/视频编解码库libavcodec，为了保证高可移植性和编解码质量，libavcodec里很多code都是从头开发的。
2.环境配置
项目中引入ijkplayer环境有两种方式。
2.1在Gradle中引入
# required
allprojects {
repositories {
jcenter()
}
}
dependencies {
# required, enough for most devices.
compile 'tv.danmaku.ijk.media:ijkplayer-java:0.6.1'
compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.6.1'
# Other ABIs: optional
compile 'tv.danmaku.ijk.media:ijkplayer-armv5:0.6.1'
compile 'tv.danmaku.ijk.media:ijkplayer-arm64:0.6.1'
compile 'tv.danmaku.ijk.media:ijkplayer-x86:0.6.1'
compile 'tv.danmaku.ijk.media:ijkplayer-x86_64:0.6.1'
# ExoPlayer as IMediaPlayer: optional, experimental
compile 'tv.danmaku.ijk.media:ijkplayer-exo:0.6.1'
}
2.2在Ubuntu下编译源码得到
Ubuntu需要安装homebrew, git, yasm
# install homebrew, git, yasm
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install git
brew install yasm
# add these lines to your ~/.bash_profile or ~/.profile
# export ANDROID_SDK=<your sdk path>
# export ANDROID_NDK=<your ndk path>
# on Cygwin (unmaintained)
# install git, make, yasm
开始编译
git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-android
cd ijkplayer-android
git checkout -B latest k0.6.1
./init-android.sh
cd android/contrib
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
cd ..
./compile-ijk.sh all
# Android Studio:
# Open an existing Android Studio project
# Select android/ijkplayer/ and import
#
# define ext block in your root build.gradle
# ext {
# compileSdkVersion = 23 // depending on your sdk version
# buildToolsVersion = "23.0.0" // depending on your build tools version
#
# targetSdkVersion = 23 // depending on your sdk version
# }
#
# Eclipse: (obselete)
# File -> New -> Project -> Android Project from Existing Code
# Select android/ and import all project
# Import appcompat-v7
# Import preference-v7
#
# Gradle
# cd ijkplayer
# gradle

3.播放器使用
可能是网络的问题，使用Gradle导入会花费很长时间，如果遇到超时，还得重头来一遍，太费时间了。后来我就直接在Ubuntu下编译后，在Android Studio下导入该项目。我先介绍下Demo中利用ijkplayer播放视频的过程。
3.1初始化播放器
IjkMediaPlayer.loadLibrariesOnce(null);
IjkMediaPlayer.native_profileBegin("libijkplayer.so");
3.2初始化IjkVideoView
//这里使用的是Demo中提供的AndroidMediaController类控制播放相关操作
mMediaController = new AndroidMediaController(this, false);
mMediaController.setSupportActionBar(actionBar);
mVideoView = (IjkVideoView) findViewById(R.id.video_view);
mVideoView.setMediaController(mMediaController);
3.3设置本地视频文件位置或服务器地址，然后播放
mVideoView.setVideoPath(mVideoPath);
mVideoView.start();
3.4Activity销毁时，需要释放资源
@Override
public void onBackPressed() {
mBackPressed = true;
super.onBackPressed();
}
@Override
protected void onStop() {
super.onStop();
//点击返回或不允许后台播放时 释放资源
if (mBackPressed || !mVideoView.isBackgroundPlayEnabled()) {
mVideoView.stopPlayback();
mVideoView.release(true);
mVideoView.stopBackgroundPlay();
} else {
mVideoView.enterBackground();
}
IjkMediaPlayer.native_profileEnd();
}
4.自定义播放器
当然官方提供的Demo只是演示视频播放的基本操作，对于视频播放的控制、全屏等操作，还要自己动手做。
4.1部分声明
private static final int SIZE_DEFAULT = 0;
private static final int SIZE_4_3 = 1;
private static final int SIZE_16_9 = 2;
private int currentSize = SIZE_16_9;
private IjkVideoView video;
private SeekBar seekBar;
4.2视频播放比例
这里需要修改IjkVideoView部分代码后，才支持按比例播放
//修改相关代码
private static final int[] s_allAspectRatio = {
IRenderView.AR_ASPECT_FIT_PARENT,
IRenderView.AR_ASPECT_FILL_PARENT,
IRenderView.AR_ASPECT_WRAP_CONTENT,
IRenderView.AR_MATCH_PARENT,
IRenderView.AR_16_9_FIT_PARENT,
IRenderView.AR_4_3_FIT_PARENT
};
private int mCurrentAspectRatioIndex = 3;//0
private int mCurrentAspectRatio = s_allAspectRatio[3];//0
private int mCurrentRender = RENDER_TEXTURE_VIEW;
//增加下面方法
public IRenderView getmRenderView() {
return mRenderView;
}
public int getmVideoWidth() {
return mVideoWidth;
}
public int getmVideoHeight() {
return mVideoHeight;
}
设置视频播放比例
public void setScreenRate(int rate) {
int width = 0;
int height = 0;
if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {// 横屏
if (rate == SIZE_DEFAULT) {
width = video.getmVideoWidth();
height = video.getmVideoHeight();
} else if (rate == SIZE_4_3) {
width = screenHeight / 3 * 4;
height = screenHeight;
} else if (rate == SIZE_16_9) {
width = screenHeight / 9 * 16;
height = screenHeight;
}
} else { //竖屏
if (rate == SIZE_DEFAULT) {
width = video.getmVideoWidth();
height = video.getmVideoHeight();
} else if (rate == SIZE_4_3) {
width = screenWidth;
height = screenWidth * 3 / 4;
} else if (rate == SIZE_16_9) {
width = screenWidth;
height = screenWidth * 9 / 16;
}
}
if (width > 0 && height > 0) {
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) video.getmRenderView().getView().getLayoutParams();
lp.width = width;
lp.height = height;
video.getmRenderView().getView().setLayoutParams(lp);
}
}
4.3屏幕方向切换
private void fullChangeScreen() {
if (getRequestedOrientation() == ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {// 切换为竖屏
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
} else {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
}
4.4全屏播放
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
//重新获取屏幕宽高
initScreenInfo();
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {//切换为横屏
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) video.getLayoutParams();
lp.height = screenHeight;
lp.width = screenWidth;
video.setLayoutParams(lp);
} else {
LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) video.getLayoutParams();
lp.height = screenWidth * 9 / 16;
lp.width = screenWidth;
video.setLayoutParams(lp);
}
setScreenRate(currentSize);
}
4.5播放进度
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
....
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
video.seekTo(seekBar.getProgress()*video.getDuration()/100);
...
}
});
//视频开始播放时使用handle.sendMessageDelayed更新时间显示
private void refreshTime(){
int totalSeconds = video.getCurrentPosition() / 1000;
int seconds = totalSeconds % 60;
int minutes = (totalSeconds / 60) % 60;
int hours = totalSeconds / 3600;
String ti=hours > 0 ? String.format("%02d:%02d:%02d", hours, minutes, seconds):String.format("%02d:%02d", minutes, seconds);
time.setText(ti);
}
