[FEATURE] add video analyzer feature

[ZZZWG1019]

这是为了给fellou提的，不是eko，啊官网fellou.ai说想要用户分享工作流以改进，连个提交分享的页面都没有。
This is for fellou,not for eko.The official site fellou.ai says it wants users to share workflows for improvement, but it doesn't even have a page for submitting shares.

Feature Summary

Like Tencent Meeting ,understand the content while playing the video,or like "get笔记"Can export transcript from video url

Use Case

students,and developers，want to watch videos while someone accompanies me, analyzing and summarizing them.

Expected Outcome

Display text in real time on the right sidebar

Additional Context

get笔记(biji.com)：You can export subtitles with just a link. Summaries aren't always necessary; exporting a verbatim transcript is important.（给一个链接就能导出字幕，总结不总要，导出逐字稿重要）
