Android ijkplayer的使用解析

ijkplayer是Bilibili基于ffmpeg开发并开源的轻量级视频播放器，支持播放本地网络视频，也支持流媒体播放。支持Android&iOS。

ijkplayer的编译这里不多阐述，我也是直接获取别人编译完成的so库文件，直接使用的。如果你对ijkplayer的编译感兴趣，可以百度一下，有很多文章。

使用ijkplayer

导包

ijkplayer源码官方下载地址：https://github.com/Bilibili/ijkplayer
上面是官方提供的ijkplayer的源码地址，但是它是没有编译过的。下面我给大家分享一份编译好的ijkplayer源码，由于比较大，分了三个包才上传完成，需要三个包都下载后才能一起解压：
编译好的ijkplayer.part1
编译好的ijkplayer.part2
编译好的ijkplayer.part3

我们下载完成，进入android/ijkplayer目录：

注：
链接库ijkplayer-arm64，ijkplayer-armv5，ijkplayer-armv7a，ijkplayer-x86，ijkplayer-x86_64是不同体系架构的动态链接库，在当前工程结构里面作为一个模块，如果不想做兼容多平台问题，可以删除其他目录结构，单独保留自己需要的平台目录。

新建一个工程：
（1）把ijkplayer-armv7a/src/main/libs下的文件拷贝到新工程app目录的libs下。
（2）把ijkplayer-java/build/outputs/aar/ijkplayer-java-release.aar复制到新工程app目录的libs下。
（3）修改APP下的build.gradle, 主要设置.so及.aar的位置:

（4）复制ijkplayer-example下面的tv.danmaku.ijk.media.example.widget.media到新的工程，删掉一些不需要类。

（5）IjkVideoView里面还是有很多如exo等没用的东西，删！具体可以参见我后面的Demo。

（6）Manifest

封装ijkplayer

上面只是ijkplayer的一个基本用法。我们可以对ijkplayer进行一次封装，让ijkplayer使用起来更加简单。

功能：

• 使用Vitamio的VideoView进行视频播放
• 视频左侧界面（左1/2以内）上下滑动调节亮度
• 视频右侧界面（右1/2以外）上下滑动调节声音
• 双击切换视频窗口布局
• 非直播状态，可以左右滑动调节当前播放进度
