YouTube实时流API中的cam在哪里? [英] Where is cam in YouTube live streaming API?

问题描述

我无法加载我的视频实时流式传输在YouTube上.我浏览了YouTube文档，尝试在Google上搜索，但没有获得成功的结果.

I am not able to load my video live streaming on YouTube. I have gone through the YouTube documentation, tried searching on Google but no result to get success.

我有一个运行完整的PHP示例代码，可以在YouTube上实时流式传输视频，并且正在广播视频，但消息却是

1. 使用代码段和状态(即插入方法)创建广播.
2. 使用CDN(1080p，rtmp)和带有摘要插入的代码段创建实时流.
3. 使用广播绑定方法将它们绑定在一起.

当我进入https://www.youtube.com/my_live_events时，它显示了创建的新事件，但我没有发现缺少使用实时流的cam的地方.

When I go to my https://www.youtube.com/my_live_events it is showing new event created, but I am not getting where is cam missing to use live streaming.

推荐答案

在步骤2中创建Live Stream对象时，将在响应中的cdn-> ingestionInfo下返回ingestionAddress.这是您的RTMP端点，您需要使用返回的streamName作为流密钥来发送视频.

When you create your Live Stream object in step 2, an ingestionAddress will be returned in the response under cdn -> ingestionInfo. This is your RTMP endpoint where you need to send your video, using the streamName returned as the stream key.

您的回复将类似于以下内容(我混淆了我的一些个人YouTube信息):

Your response will look something like this (I've obfuscated some of my personal YouTube info):

{
    cdn =     {
        format = 480p;
        ingestionInfo =         {
            backupIngestionAddress = "rtmp://b.rtmp.youtube.com/live2?backup=1";

            ingestionAddress = "rtmp://a.rtmp.youtube.com/live2";
            streamName = "xxxxxx";
        };
        ingestionType = rtmp;
    };
    etag = "\"xxxxxx\"";
    id = "xxxxxx";
    kind = "youtube#liveStream";
    snippet =     {
        channelId = "xxxxxx";
        description = "";
        publishedAt = "2015-04-15T14:33:43.000Z";
        title = "live_stream_test";
    };
}
