How to stop AutoPlay video in the browser?

To stop the AutoPlay of videos in a web browser, you can use the `autoplay` query parameter when embedding a video on a website or web application. 

For example, you can set `autoplay` to `false` or `0` to prevent autoplay:

https://your-video-player-url.com?autoplay=false

Or:

https://your-video-player-url.com?autoplay=0

Please note that the availability and behaviour of these parameters depend on the video player and platform being used.

Note: ‘true’ = ‘1’ and ‘false’ = ‘0’. You can use either ‘true’ or ‘1’, and ‘false’ or ‘0’.
