Hi there.
When you say to scrap video, do you mean to download the video or to store its URL along with the title of the video? Or, I should download the video that has a name same as the title of the video?
What would be the mechanism of the extension, should it auto-scroll forever and try finding those videos or on an extension click, it should scan the page for those videos and download them?
Anyways, feel free to hit me up so we can talk more about this. I am very responsive. All the best
