YouTube 网址参数问题.YouTube 不使用 HTTP 范围 [英] YouTube URL parameters issue. YouTube not using HTTP ranges

问题描述

我想了解 YouTube 视频的所有参数，因为 YouTube 现在不使用 HTTP 范围元素，而是在其 URL 中使用自己的范围参数，因此我无法像我看到的那样使用 Wireshark 进行会话许多 HTTP 200 可以与 video/x-flv 一起使用，因此我的播放器在读取 HTTP 响应及其范围时无法将它们关联起来.以下是 YouTube 为单个视频发送的示例 URL.是否也有任何可用的文档?

I want to understand all the parameters of a YouTube video as YouTube is now not using the HTTP range element but using its own range parameters inside its URL and thus I am not able to make a session using the Wireshark as i see so many HTTP 200 ok with video/x-flv and thus my player is not able to associate them as it reads the HTTP responses and its ranges. Here are the sample URLs what YouTube is sending for a single video. Is there any documetation available for this as well?
