ijkplayer 是一款做视频直播的框架, 基于ffmpeg, 支持 Android 和 iOS,
<h2>一. 下载ijkplayer</h2>
ijkplayer下载地址:https://github.com/Bilibili/ijkplayer
下载完成后解压, 解压后文件夹内部目录如下图:
1.png
<h2>二. 编译 ijkplayer</h2>
说是编译ijkplayer, 其实是编译 ffmpeg, 在这里我们已经下载好了ijkplayer, 所以 github 上README.md中的Build iOS那一步中有一些步骤是不需要的.
下面开始一步一步编译:
1.打开终端, cd到ijkplayer-master文件夹中, 也就是下载完解压后的文件夹, 如下图:
2.png
进入到这个文件夹
2.执行命令行./init-ios.sh, 这一步是去下载ffmpeg的, 时间会久一点, 耐心等一下.如下图:
3.png
3.在第2步中下载完成后, 执行cd ios, 也就是进入到ios目录中, 如下图:
4.png
进入ios 文件夹
4.进入
ios文件夹后, 在终端依次执行./compile-ffmpeg.sh clean和./compile-ffmpeg.sh all命令, 编译 ffmpeg, 也就是README.md中这两步, 如下图:
5.png
编译时间较久, 耐心等待一下.
<h2>三. 打包IJKMediaFramework.framework框架</h2>
集成ijkplayer 有两种方法:
一种方法是按照IJKMediaDemo工程中那样, 直接导入工程IJKMediaPlayer.xcodeproj,在这里不做介绍, 如下图:
6.png
导入IJKMediaPlayer.xcodeproj
第二种集成方法是把ijkplayer 打包成framework导入工程中使用. 下面开始介绍如何打包IJKMediaFramework.framework, 按下面步骤开始一步一步做:
1.首先打开工程IJKMediaPlayer.xcodeproj, 位置如下图:
7.png
打开后是这样的, 如下图:
8.png
2.工程打开后设置工程的 scheme, 具体步骤如下图:
9.png
10.png
3.设置好
scheme 后, 分别选择真机和模拟器进行编译, 编译完成后, 进入 Finder, 如下图:
11.png
进入 Finder 后, 可以看到有真机和模拟器两个版本的编译结果, 如下图:
12.png
下面开始合并真机和模拟器版本的 framework, 注意不要合并错了, 合并的是这个文件, 如下图:
13.png
打开终端, 进行合并, 命令行具体格式为:
lipo -create "真机版本路径" "模拟器版本路径" -output "合并后的文件路径"
合并后如下图:
15.png
下面很重要, 需要用合并后的IJKMediaFramework把原来的IJKMediaFramework替换掉, 如下图, 希望你能看懂:
16.png
上图中的1、2两步完成后, 绿色框住的那个IJKMediaFramework.framework文件就是我们需要的框架了, 可以复制出来, 稍后我们需要导入工程使用.
</h2>四. iOS工程中集成ijkplayer</h2>
新建工程, 导入合并后的IJKMediaFramework.framework以及相关依赖框架以及相关依赖框架,如下图:
1803339-391a45a214aae76a.png
导入 framework及依赖框架.png
导入框架后, 在
ViewController.m进行测试, 首先导入IJKMediaFramework.h头文件, 编译看有没有错, 如果没有错说明集成成功.
<h1>ijkplayer 集成完毕下面是代码</h1>
- 主要是从下载的IJKsdk中扒的一些通知，监听
- 创建毛玻璃
- 初始化控件
