• 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;

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];
}

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

• 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];
    }
}

三.投屏

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

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];
}
