我正在开发 LL-HLS 功能。
在Safari中播放我开发的LL-HLS时,EXT-X-RENDITION-REPORT标签似乎在ABR更改resoution时不起作用
更改分辨率时,提出以下要求。
在 hls.js 中,当更改为不同的分辨率时,确认立即包含 _HLS_msn 和 _HLS_part 查询字符串。
操作系统:macOS (Ventura 13.2.1) 浏览器:Safari 16.3

Safari 中的网络
我尝试在 EXT-X-RENDITION-REPORT 标记的 URL 属性中以各种模式(例如绝对路径和相对路径)放置路径,但是没有用。
这是 EXT-X-RENDITION-REPORT 标签的行为吗?如果没有,请告诉我需要更正的部分,我将不胜感激。
