安卓开发 - B站开源的ijkplayer播放器配置使用_android getvideooutputframespersecond();

起因

最近需要使用到播放器，自带的播放器真的烂，网上其实资料根本不多，虽然有几个开源的大项目，但是都没有什么教程，说的非常模糊，找到的博客也同样说的很模糊，很难自己二次开发啊。
先说收ijkplayer的使用。引入项目大概需要以下四步

1. 引入依赖
2. 添加配置文件
3. 引入so库（我不知道有了依赖后还要不要这个库）
4. 代码引入

配置

依赖

在build.gradle中添加依赖，根据自己需求添加

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    androidTestCompile('com.android.support:support-annotations:26.1.0') {
        force = true
    }
    ......
    //哔站的ijkplayer
    compile 'tv.danmaku.ijk.media:ijkplayer-java:0.8.8'
    compile 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.8'

    compile 'tv.danmaku.ijk.media:ijkplayer-armv5:0.8.8'
    compile 'tv.danmaku.ijk.media:ijkplayer-arm64:0.8.8'
    compile 'tv.danmaku.ijk.media:ijkplayer-x86:0.8.8'
    compile 'tv.danmaku.ijk.media:ijkplayer-x86_64:0.8.8'
//
    compile 'tv.danmaku.ijk.media:ijkplayer-exo:0.8.8'
//    compile 'tv.danmaku.ijk.media:ijkplayer-java:0.6.2'

这就是所有需要的文件了。

引入库

点击此处下载编译好的so库。
在ijkplayerso文件夹中将libs文件夹中的几个文件夹复制到自己项目的app的libs文件夹中。

代码引入

布局文件

<FrameLayout
        android:layout_width="400dp"
        android:layout_height="300dp">
        <com.example.k.bilibiliapi.video.IjkVideoView
            android:id="@+id/video_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

缺点

只有基本的播放，没有设置缓冲图，没有控制按钮，返回的时候没有释放资源，会一直播放停不下来。

实在太卡了，我也不知道我为什么这么傻把代码全放上来，这就是基本的配置使用，等有空我会把文件上传了。
