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
https://github.com/plutinosoft/Platinum
Platinum: a modular UPnP Framework [Platinum depends on Neptune]
https://github.com/plutinosoft/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<WebPolicyDecisionListener>)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<objs.length;i++){\
imgScr = imgScr + objs[i].href + '+';\
};\
return imgScr;\
};";
[webView stringByEvaluatingJavaScriptFromString:jsGetImages];//注入js方法
NSString *urlResurlt = [webView stringByEvaluatingJavaScriptFromString:@"getUrls()"];
self.mUrlArray = [NSMutableArray arrayWithArray:[urlResurlt componentsSeparatedByString:@"+"]];
if (self.mUrlArray.count > 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];
}
}
}
