Bug 275456 – Canvas to Video with captureStream no Autoplay

• Status: NEW
• Component: Media

Video Elements that have captureStream() as input won't autoplay. Or they do, but I don't know when. U can see in this example that u have to drag the teapot.

In my project the canvas is not interactive so I don't know how to trigger the autoplay. Here is a simple example

Your example autoplays for me on macOS. 

If you are testing on iOS, have  you tried adding the `playsinline` attribute (https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video#playsinline)?

Strange, for me it's not. I updated the Hardware section. So I'm testing on Safari 17. But also mobile with the playsinline attribute, it's not working for me. iOS 17.4.1
