• iOS上实现DLNA功能Github上搜一下大多是基于C++的Platinum,于是就想能不能靠OC实现一套方便iOS开发者.于是就有了MRDLNA这个库.

• DLNA投屏的相关的介绍,协议,具体XML内容就不细说了. 这里介绍一下 MRDLNA这个库的投屏使用.

支持Pod安装MRDLNA

一.搜索设备

设置好代理
self.dlnaManager = [MRDLNA sharedMRDLNAManager];
self.dlnaManager.delegate = self;
复制代码

调用开始搜索后就会搜索整个局域网中支持投视频的设备
- (void)viewWillAppear:(BOOL)animated{[super viewWillAppear:animated];[self.dlnaManager startSearch];
}
复制代码

二.发现设备后的回调

发现设备后在代理中可以拿到
- (void)searchDLNAResult:(NSArray *)devicesArray{NSLog(@"发现设备");self.deviceArr = devicesArray;[self.dlnaTable reloadData];
}//devicesArray中拿到的是CLUPnPDevice类型的对象
复制代码

• Demo中将搜索页面和投屏控制页面分开来的,所以在搜索页面搜索到设备后就把目标设备和播放Url设置给了dlnaManager

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{NSString *testUrl = @"http://223.110.239.40:6060/cntvmobile/vod/p_cntvmobile00000000000020150518/m_cntvmobile00000000000659727681";[tableView deselectRowAtIndexPath:indexPath animated:YES];if (indexPath.row < self.deviceArr.count) {CLUPnPDevice *model = self.deviceArr[indexPath.row];self.dlnaManager.device = model;self.dlnaManager.playUrl = testUrl;DLNAControlVC *controlVC = [[DLNAControlVC alloc] init];controlVC.model = model;[self.navigationController pushViewController:controlVC animated:YES];}
}
复制代码

三.投屏

- (void)viewDidLoad {[super viewDidLoad];self.dlnaManager = [MRDLNA sharedMRDLNAManager];[self.dlnaManager startDLNA];
}
复制代码

四.投屏后的播放控制

/**退出*/
- (IBAction)closeAction:(id)sender {[self.dlnaManager endDLNA];
}/**播放/暂停*/
- (IBAction)playOrPause:(id)sender {if (_isPlaying) {[self.dlnaManager dlnaPause];}else{[self.dlnaManager dlnaPlay];}_isPlaying = !_isPlaying;
}/**进度条seek单位是秒*/
- (IBAction)seekChanged:(UISlider *)sender{NSInteger sec = sender.value * 60 * 60;NSLog(@"播放进度条======>: %zd",sec);[self.dlnaManager seekChanged:sec];
}/**音量volume建议传0-100之间字符串*/
- (IBAction)volumeChange:(UISlider *)sender {NSString *vol = [NSString stringWithFormat:@"%.f",sender.value * 100];NSLog(@"音量========>: %@",vol);[self.dlnaManager volumeChanged:vol];
}/**切集*/
- (IBAction)playNext:(id)sender {NSString *testVideo = @"http://wvideo.spriteapp.cn/video/2016/0328/56f8ec01d9bfe_wpd.mp4";[self.dlnaManager playTheURL:testVideo];
}
