iOS视频播放之ijkplayer使用

记录ijkplayer从一无所知到播放这个流程

  1. 先cd到你喜爱的目录下

    image
  2. Build iOS
    执行git clone https://github.com/Bilibili/ijkplayer.git ijkplayer-ios克隆ijkplayer-ios

    image
  3. 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

    image
  4. 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

    image
  5. cd到ios文件夹,运行脚本./compile-ffmpeg.sh clean./compile-ffmpeg.sh all

  1. 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./compile-ffmpeg.sh all

  1. 再次编译IJKMediaDemo.xcodeproj成功,选择运行IJKMediaDemo
    选择Online Samples即可播放M3U8

    image
  2. 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

    image
    image
  3. 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

image

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

  1. 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

  2. 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
    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

  1. 导入ijkplayer的readme中提到的相关库
![image](//upload-images.jianshu.io/upload_images/3115781-60e2de39702554f9.png?imageMogr2/auto-orient/strip|imageView2/2/w/942/format/webp)
  1. 再次Build还是link错误,不过这次编程了__gxx_personality_v0…,

  1. 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 
@interface ViewController ()
@property (atomic, retain) id  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

  1. 综上所述,只要有合成好的framework,把它拖到工程当中,Link相关库即可播放,请参考OCDemo或SwiftDemo
    如有问题,欢迎反馈,谢谢!
