macOS开发AirPlay||DLNA总结

DLNA的全称是DIGITAL LIVING NETWORK ALLIANCE(数字生活网络联盟)， 其宗旨是Enjoy your music, photos and videos, anywhere anytime， DLNA(Digital Living Network Alliance) 由索尼、英特尔、微软等发起成立、旨在解决个人PC，消费电器，移动设备在内的无线网络和有线网络的互联互通，使得数字媒体和内容服务的无限制的共享和增长成为可能，目前成员公司已达280多家。

1、使用第三方库Neptune和Platinum

下载Platinum工程，carthage update安装，打开universal-apple-macosx工程编译生成Platinum.framework和Neptune.framework

Neptune : a C++ Runtime Library

Platinum: a modular UPnP Framework [Platinum depends on Neptune]

2、对Platinum库进行封装实现DLNA扫描连接等功能

开启代理，启动搜索

[[[ZM_SingletonControlModel sharedInstance] DMRControl] setDelegate:self];
//启动DMC去搜索设备
if (![[[ZM_SingletonControlModel sharedInstance] DMRControl] isRunning]) {
    [[[ZM_SingletonControlModel sharedInstance] DMRControl] start];
}

搜索到设备，开始连接

#pragma mark - ZM_DMRProtocolDelegate
- (void)onDMRAdded {
    NSLog(@"%s",__FUNCTION__);
    
    NSArray *devices = [[NSMutableArray alloc] initWithArray:[[[ZM_SingletonControlModel sharedInstance] DMRControl] getActiveRenders]];
    [devices enumerateObjectsUsingBlock:^(ZM_RenderDeviceModel  * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSLog(@"搜索到设备%@", obj.name);
    }];
    
    if (devices.count <= 0) {
        return;
    }
    
    NSLog(@"开始连接设备");
    
    [[[ZM_SingletonControlModel sharedInstance] DMRControl] chooseRenderWithUUID:[devices[0]uuid]];
    ZM_RenderDeviceModel *model = [[[ZM_SingletonControlModel sharedInstance] DMRControl] getCurrentRender];
    
    self.title = [NSString stringWithFormat:@"已连接盒子%@", [devices[0] name]];
    
    NSLog(@"连接设备设备名%@，设备地址%@", model.name, model.descriptionURL);
}

开始播放视频连接

    if ([[[ZM_SingletonControlModel sharedInstance] DMRControl] getCurrentRender]) {
        [[[ZM_SingletonControlModel sharedInstance] DMRControl] renderSetAVTransportWithURI:@"视频地址" metaData:nil];
        [[[ZM_SingletonControlModel sharedInstance] DMRControl] renderPlay];
    }

3、实现播放webview视频连接功能

#pragma mark - WebPolicyDelegate
//获取每次加载页面的request
- (void)webView:(WebView *)webView decidePolicyForMIMEType:(NSString *)type
        request:(NSURLRequest *)request
          frame:(WebFrame *)frame
decisionListener:(id)listener{
    
    NSLog(@"request=======%@",request);
    
    NSString *aUrlString = request.URL.absoluteString;
    
    if (![aUrlString hasSuffix:@"mkv"]) {
        return;
    }
    
    [listener ignore];
    
    //这里是js，主要目的实现对url的获取
    static  NSString * const jsGetImages =
    @"function getUrls(){\
    var objs = document.getElementsByTagName(\"a\");\
    var imgScr = '';\
    for(var i=0;i 0) {
        self.currentIdx = [self.mUrlArray indexOfObject:aUrlString];
        
        if (self.currentIdx < 0) {
            return;
        }
        
        NSLog(@"开始播放%@", aUrlString);

        if ([[[ZM_SingletonControlModel sharedInstance] DMRControl] getCurrentRender]) {
            [[[ZM_SingletonControlModel sharedInstance] DMRControl] renderSetAVTransportWithURI:self.mUrlArray[self.currentIdx] metaData:nil];
            [[[ZM_SingletonControlModel sharedInstance] DMRControl] renderPlay];
        }
    }
}
