Bug Summary

Hello, good morning, I am currently using invidio.io artificial intelligence to create videos, and when I finish creating the video a banner appears telling me that the browser's video player is not valid.

Reproduction Steps

Go to the invideo.io website
Go to the generate text to video section
Create a video from prompts
You will be able to see that once the process is finished, the sign appears that the browser's video player is not valid.

Expected Behavior

The expected behavior is that the previously mentioned sign does not appear, that the web browser video player is not valid and so I can view the video that I have created with artificial intelligence

Actual Behavior

The aforementioned poster appears preventing me from seeing the video I created

There are sites and platforms that are exclusively for Chrome or Edge chromium browsers, while support is resolved and extended to new formats and new technologies, you can change the user agent and without leaving Firefox you can emulate Midori as if you were in Chrome.
