记录ijkplayer从一无所知到播放这个流程
- 先cd到你喜爱的目录下
- Build iOS
执行git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios克隆ijkplayer-ios
- cd到ijkplayer-ios文件夹下创建新分支并切换过去
git checkout -B latest k0.8.8
- 分支创建完后运行脚本
./init-ios.sh
pull gas-preprocessor base
pull ffmpeg base
pull ffmpeg fork armv7
pull ffmpeg fork arm64
pull ffmpeg fork i386
pull ffmpeg fork x86_64\
- cd到ios文件夹，运行脚本
./compile-ffmpeg.sh clean和./compile-ffmpeg.sh all
- 编译IJKMediaDemo.xcodeproj可能会报错
'libavformat/avformat.h' file not found
发现问题就在issues里找答案，参考#1251
1.进入ijkplayer-ios/ios/compile-ffmpeg.sh
2.找到这一行 FF_ALL_ARCHS_IOS8_SDK="armv7 arm64 i386 x86_64"
3.删除掉其中的 armv7
4.回到ijkplayer-ios/ios，并执行
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all
其实，在执行./compile-ffmpeg.sh all的时候已经报错了，只是选择了忽略
现在，删掉armv7抛弃iPhone5s之前的机型。重新运行脚本./compile-ffmpeg.sh clean和./compile-ffmpeg.sh all
- 再次编译IJKMediaDemo.xcodeproj成功，选择运行IJKMediaDemo
选择Online Samples即可播放M3U8
- Demo运行没问题就可以拷贝资源文件到自己的项目中去播放了。也可单独运行IJKMediaPlayer.xcodeproj生成IJKMediaFramework.framework
- 模拟器运行出来的只能在模拟器上运行，真机调试运行的只能在真机上运行，这里就需要合并framework
这是两个不同的运行环境，需要合并IJKMediaFramework.framework下的IJKMediaFramework
运行命令行：
lipo -create /Users/mac/Desktop/ijk/framework/phone/IJKMediaFramework /Users/mac/Desktop/ijk/framework/simulator/IJKMediaFramework -output /Users/mac/Desktop/ijk/framework/IJKMediaFramework
验证是否合并成功就是lipo中的IJKMediaFramework是否生产，还有就是使用lipo -info查看文件属性吧算是会提示x86_64 arm64
arm64表示是真机的文件，x86_64表示是模拟器支持的文件，显示两个就表示合并成功
-
注意区分debug版本还是release版本，调试阶段使用debug就行，这个切换在Xcode中product->scheme->edit scheme中更改
-
有了库文件就可以拖到自己的工程中使用了，OC的项目导入
#import <IJKMediaFramework/IJKMediaFramework.h>
Build一下 success，然后导入视频地址测试http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8播放，编译link错误
- 导入ijkplayer的readme中提到的相关库
- 再次Build还是link错误，不过这次编程了__gxx_personality_v0…，
- 这是还差一个库以前是libstdc++.tbd，现在是
libc++.1.tbd，导入即可；故事板中拉个uiview(显示播放界面)、button(控制播放、暂停)
#import "ViewController.h"
#import <IJKMediaFramework/IJKMediaFramework.h>
@interface ViewController ()
@property (atomic, retain) id <IJKMediaPlayback> player;
@property (weak, nonatomic) IBOutlet UIView *playView;
@property (weak, nonatomic) IBOutlet UIButton *playBtn;
@end
@implementation ViewController
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
if (![_player isPlaying]) {
[self.player prepareToPlay];
}
}
-(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
NSURL *url = [NSURL URLWithString:@"http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8"];
_player = [[IJKFFMoviePlayerController alloc] initWithContentURL:url withOptions:nil];
UIView *playerView = [_player view];
playerView.frame = self.playView.frame;
[self.view addSubview:playerView];
}
-(IBAction)clickedAction:(id)sender {
if (![_player isPlaying]) {
[self.player play];
[self.playBtn setTitle:@"Pause" forState:UIControlStateNormal];
}else {
[self.player pause];
[self.playBtn setTitle:@"Play" forState:UIControlStateNormal];
}
}
@end

补充
1、编译真机时报错
IJKMediaPlayer.xcodeproj The linked library 'libavformat.a' is missing one or more architectures required by this target: armv7.
解决： 在Target - Build Settings - Excluded Architectures添加如下：
EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64=arm64 arm64e armv7 armv7s armv6 armv8 EXCLUDED_ARCHS=$(inherited) $(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT))
2、合并framework时 报错
IJKMediaFramework have the same architectures (arm64) and can't be in the same fat output file
解决： 在Target - Build Settings - Excluded Architectures添加如下：
- 点击右侧加号，添加Any iOS Simulator SDK
- 在Any iOS Simulator SDK 后面添加arm64。 这样编译出来的包中就不会包含arm64了。
3、进入Xcode/DerivedData/.../Products目录，使用 lipo -create 真机路径 模拟器路径 -output 真机路径 将二者framework合并输出： cd /Users/lf/Library/Developer/Xcode/DerivedData/IJKMediaDemo-cvfdngeaecgjswfsdaurcwyraeah/Build/Products
lipo -create Release-iphoneos/IJKMediaFramework.framework/IJKMediaFramework Release-iphonesimulator/IJKMediaFramework.framework/IJKMediaFramework -output /Users/lf/Desktop/iOS/IJKMediaFramework
通过 lipo -info IJKMediaFramework 命令查看 framework 支持情况。可看到现在这个真机、模拟器都是支持的。
lipo -info /Users/lf/Desktop/iOS/IJKMediaFramework
将合并后的 framework 拷贝到 Release-iphoneos/IJKMediaFramework.framework 真机文件夹中覆盖
4、将合并后的 真机IJKMediaFramework.framework（Release-iphoneos/IJKMediaFramework.framework）添加到我们项目中来
5、添加一些依赖的动态库。(Xcode13不需要添加了)
AudioToolbox.framework
AVFoundation.framework
CoreGraphics.framework
CoreMedia.framework
CoreVideo.framework
libbz2.tbd
libz.tbd
MediaPlayer.framework
MobileCoreServices.framework
OpenGLES.framework
QuartzCore.framework
UIKit.framework
VideoToolbox.framework
6、样例代码
import UIKit
import IJKMediaFramework
class PhoneNumberLoginVC: BaseVC {
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// 开始播放
if !playerVC.isPlaying() {
playerVC.prepareToPlay()
}
}
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
// 关闭播放器
playerVC.shutdown()
}
override func initSubViews() {
super.initSubViews()
view.addSubview(playerVC.view)
playerVC.view.snp.makeConstraints { make in
make.edges.equalTo(view)
}
}
lazy var playerVC: IJKFFMoviePlayerController = {
let ijkFFOptions = IJKFFOptions.byDefault()
// 视频源地址
// 美国1
// let url = URL(string: "rtmp://media3.scctv.net/live/scctv_800")
// 中东
let url = URL(string: "rtmp://ns8.indexforce.com/home/mystream")
// 韩国朝鲜日报
// let url = URL(string: "rtmp://mobliestream.c3tv.com:554/live/goodtv.sdp")
let vc = IJKFFMoviePlayerController.init(contentURL: url, with: ijkFFOptions!)
// 缩放模式
vc?.scalingMode = .aspectFit
// 开启自动播放
vc?.shouldAutoplay = true
return vc!
}()
}
