Hi @KirylAkulich1 . Can you provide any more details about the context of this? Android/Webview version? A specific video or any video? Was it autoplay and autoplay stopped working without mute/unmute?

Hi. We have tested on Android 12/13. WebView version - Android System WebView 117.0.5938.60.
Unfortunately I can not provide any videos( It not even started to play. I tried to tap play button, but nothing happened.But If I set MediaPlaybackRequiresUserGesture setting to false - everything works. Do you have any idea why it could happen?

Was the same code working previously in earlier versions of the Webviews? What does you code look like?

[KirylAkulich1]

I can reveal some html element properties:

<iframe> has next properties: <iframe src="some_src" frameborder="0" allow="autoplay; fullscreen" allowfullscreen="" title="some_title"></iframe>

I have not updated web view. Previously video played correctly. Previously MediaPlaybackRequiresUserGesture flag was not used.

Are you able to see any debug information from the page loaded in the Webview? Like do you see any Javascript errors in the Javascript console for the page?

[KirylAkulich1]

Yes I am.
I do not see any specific errors.

I get some errors if try to drag progress bar

I have found a way to demo a problem:

Video plays only when it is muted. Code to reproduce https://codepen.io/KirylAkulich1/pen/WNLgzBK

I have found an interesting thing about playsinline=0& parameter. If I remove it then video is played fine in full/inline modes.
So what we have now: If playsinline=0& is present in video url then video is played only if MediaPlaybackRequiresUserGesture is set to false in WebView settings. If playsinline=0& is not present then is played.

Hey @KirylAkulich1, thanks for reporting this issue. I've added a ticket to our internal system to investigate. We'll reply to this issue when we have updates. Thanks!
