Description

你好！当从文件里读取URLs来并使用cookies来下载B站大会员高清1080P+的视频时，只有前两个（有时只有第一个）视频的下载是“高清 1080P+/60”，之后的下载开始视频质量变成了“高清 1080P“。比如当我从“list.txt"文件读取并下载以下四个视频：

https://www.bilibili.com/video/av44924522
https://www.bilibili.com/video/av44665613
https://www.bilibili.com/video/av44740863
https://www.bilibili.com/video/av44362828

开启debug模式后，命令行的记录如下：pastebin [link（抱歉记录很长，我不确定该如何筛选）；删除cookies后的记录：pastebin link；下载的第一个视频是1080P+，第二个开始变成了1080P。

请问大家有过类似的问题吗，有没有什么建议的解决方法呢？

十分感谢！
