In a MAUI Blazor app, when you try to make an iframe video to run full screen in android devices, nothing happens.

Steps to Reproduce

  1. Create a new MAUI Blazor app

Example below <iframe width="684" height="385" src="https://www.youtube.com/embed/sGYIDKx6cY0" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

@efonsecab thank you for the report. For this part:

Try to make the video to play full screen

Do the usual controls for attempting to show full screen show up, but when you tap it, nothing happens? Or does the full screen button not even show up?

jfversluis commented 2 years ago

Maybe (partially) related to #4807 ? @efonsecab did you also test on iOS or Windows? Does it work properly there?

Yes, the controls appear, it's just that the full screen action is not executing. I just confirmed the issue also happens when using Azure Media Player. I updated the Relevant log output for this scenario.

@efonsecab to help us isolate this issue, can you please confirm if the issue also reproduces in the base MAUI WebView (without Blazor)?

Yes, same issue with a normal MAUI app with a WebView.

Seems related/duplicate of this: https://github.com/dotnet/maui/issues/7720

Works fine on Windows . ``` <iframe allowfullscreen="allowfullscreen" ..../>

I'm facing this issue as well. I have on my Maui App 7.0.x a webview playing a video and it does not allow for full screen in Android. On iOS it works natively.

vhugogarcia commented 1 year ago

Hello friends, I found a solution and I wrote an article about how to implement it, hopefully you find it helpful :)

In this post, I will show you how to enable the feature allowing users to watch videos in full-screen mode on .NET MAUI WebViews for Android, using a simple custom handler and some native code. https://dev.to/vhugogarcia/net-maui-webviews-how-to-play-videos-in-full-screen-1j03

Thank you all!
