.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'
}

# 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

目录结构

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);
}
}
