won't record already-playing video

[poindoink]

If I go to a site that has a video playing and I hit record, it won't start. I have to refresh the page. How do I get it to start recording already-playing video?

In my experience it can not be done.

Same here. I think the script is set to record at the beginning of the video. Do you get any error message on this?https://imagicon.info/cat/14-16/1.gif
