3.1.2 下载并编译iOS版的

ijkplayer

#下载 ijkplayer-ios
git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios
#到` ijkplayer-ios`目录中
cd ijkplayer-ios
#切换到 `k0.5.1` 分支
git checkout -B latest k0.5.1
#运行iOS初始化脚本
./init-ios.sh
#进入到 iOS 文件夹
cd iOS
#清空编译
./compile-ffmpeg.sh clean
#编译全部,比较耗时,需要等待
./compile-ffmpeg.sh all
#使用Xcode打开ios文件夹下面的 IJKMediaPlayer 项目,分别在模拟器和真机上编译IJKMediaFramework.framework.

lips -create 文件1
文件2 -o 要生成文件

注意:在测试阶段可以使用合并后的framework,当打包时候最好只使用真机的framework以减小安装包的大小

IJKMediaFramework.framework

- (void)viewDidLoad {
[super viewDidLoad];
//1. 根据当前环境设置日志信息
//1.1如果是Debug状态的
#ifdef DEBUG
//  设置报告日志
[IJKFFMoviePlayerController setLogReport:YES];
//  设置日志的级别为Debug
[IJKFFMoviePlayerController setLogLevel:k_IJK_LOG_DEBUG];
//1.2否则(如果不是debug状态的)
#else
//  设置不报告日志
[IJKFFMoviePlayerController setLogReport:NO];
//  设置日志级别为信息
[IJKFFMoviePlayerController setLogLevel:k_IJK_LOG_INFO];
#endif

// 2. 检查版本是否匹配
[IJKFFMoviePlayerController checkIfFFmpegVersionMatch:YES];
// 3.  创建IJKFFMoviePlayerController
// 3.1 默认选项配置
IJKFFOptions *options = [IJKFFOptions optionsByDefault];
// 3.2 创建播放控制器
IJKFFMoviePlayerController *ffMoviePlayerController = [[IJKFFMoviePlayerController alloc] initWithContentURLString:@"rtmp://192.168.41.35:1935/gzhm/room" withOptions: options];
//4. 屏幕适配
// 4.1 设置播放视频视图的frame与控制器的View的bounds一致
self.player.view.frame = self.view.bounds;
// 4.2 设置适配横竖屏(设置四边固定,长宽灵活)
self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
//  4.3 设置播放视图的缩放模式
self.player.scalingMode = IJKMPMovieScalingModeAspectFit;
//  4.4 设置自动播放
self.player.shouldAutoplay = YES;
//  4.5 自动更新子视图的大小
self.view.autoresizesSubviews = YES;
//  4.6 添加播放视图到控制器的View
[self.view addSubview:self.player.view];
}

#pragma mark - 视图即将显示
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
//  当试图即将展示的时候开始播放
[self.player prepareToPlay];
}
#pragma mark - 视图已经消失
- (void)viewDidDisappear:(BOOL)animated {
[super viewDidDisappear:animated];
//  关闭播放
[self.player shutdown];
}

- (IBAction)play:(id)sender {
//  播放
[self.player play];
}
- (IBAction)pause:(id)sender {
// 暂停
[self.player pause];
}
