How can I show videos in web browser widget?

Hello, I’m having an issue with the web browser widget, I’m linking to so users in a virtual comunity can have access to free movies while in the game. The page loads fine but as soon as the video player opens, the video won’t start. If i browse the same page outside of UE4 the video plays just fine. Any suggestions?


Have you solved this issue? I am experiencing the same in UE5.1. The video element is displayed (including controls and a poster image), but the play button is greyed out and nothing happens when I call the element’s play() function from JavaScript.

I dug a little deeper and found there were some video that did play. The reasons seems to be that Chromium does not support the H264 codec, presumably because it is proprietary. See also Audio/Video.
