视频捕获是什么意思？

[vividFeng]

What does video capture mean? Does it allow the video element to get the focus event or save the video like screen recording? I only know that turning on video capture shows on and turning off shows off, but I don't know what it does. If it saves the video like screen recording, where is the video file?

It's an API for allowing extension to manipulate media stream, like adjust volume: https://developer.chrome.com/docs/extensions/reference/api/tabCapture

Maybe it is necessary to add relevant comments. Users who are not familiar with this API will only associate it with video recording and video image capture.
