iOS视频播放之ijkplayer使用-六虎

记录ijkplayer从一窍不通到播映这个流程

Build iOS
履行git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios克隆ijkplayer-ios

cd到ijkplayer-ios文件夹下创立新分支并切换曩昔git checkout -B latest k0.8.8

分支创立完后运转脚本./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，运转脚本./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，参阅#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，并履行
./compile-ffmpeg.sh clean
./compile-ffmpeg.sh all

其实，在履行./compile-ffmpeg.sh all的时候已经报错了，只是挑选了忽略

现在，删掉armv7扔掉iPhone5s之前的机型。重新运转脚本./compile-ffmpeg.sh clean和./compile-ffmpeg.sh all

再次编译IJKMediaDemo.xcodeproj成功，挑选运转IJKMediaDemo
挑选Online Samples即可播映M3U8

Demo运转没问题就可以拷贝资源文件到自己的项目中去播映了。也可单独运转IJKMediaPlayer.xcodeproj生成IJKMediaFramework.framework

模拟器运转出来的只能在模拟器上运转，真机调试运转的只能在真机上运转，这里就需要兼并framework
这是两个不同的运转环境，需要兼并IJKMediaFramework.framework下的IJKMediaFramework
运转命令行：

lipo -create /Users/mac/Desktop/ijk/framework/phone/IJKMediaFramework /Users/mac/Desktop/ijk/framework/simulator/IJKMediaFramework -output /Users/mac/Desktop/ijk/framework/IJKMediaFramework

验证是否兼并成功就是lipo中的IJKMediaFramework是否生产，还有就是运用lipo -info查看文件特点吧算是会提示x86_64 arm64
arm64表明是真机的文件，x86_64表明是模拟器支持的文件，显现两个就表明兼并成功

留意区别debug版别仍是release版别，调试阶段运用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运用了，OC的项目导入#import <IJKMediaFramework/IJKMediaFramework.h>
Build一下 success，然后导入视频地址测验http://devimages.apple.com.edgekey.net/streaming/examples/bipbop_4x3/bipbop_4x3_variant.m3u8播映，编译link过错

导入ijkplayer的readme中提到的相关库

再次Build仍是link过错，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(显现播映界面)、button(操控播映、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

综上所述，只需有合成好的framework，把它拖到工程当中，Link相关库即可播映，请参阅OCDemo或SwiftDemo
如有问题，欢迎反馈，谢谢！

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.

处理： 在Target – Build Settings – Excluded Architectures增加如下：

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、兼并framework时报错

IJKMediaFramework have the same architectures (arm64) and can't be in the same fat output file

处理： 在Target – Build Settings – Excluded Architectures增加如下：

点击右侧加号，增加Any iOS Simulator SDK
在Any iOS Simulator SDK 后面增加arm64。这样编译出来的包中就不会包括arm64了。

3、进入Xcode/DerivedData/…/Products目录，运用 `lipo -create 真机途径模拟器途径 -output 真机途径` 将二者framework兼并输出： `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

将兼并后的framework拷贝到Release-iphoneos/IJKMediaFramework.framework 真机文件夹中掩盖

4、将兼并后的`真机IJKMediaFramework.framework`（Release-iphoneos/IJKMediaFramework.framework）增加到咱们项目中来

5、增加一些依靠的动态库。(Xcode13不需要增加了)

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)
    // 开始播映
    if !playerVC.isPlaying() {
      playerVC.prepareToPlay()
    }
  }
  override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    // 封闭播映器
    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!)
    // 缩放形式
    vc?.scalingMode = .aspectFit
    // 敞开自动播映
    vc?.shouldAutoplay = true
    return vc!
  }()
}
