This is my video player module for Joomla 4.0 and later versions.
I use it on my private website.
The video itself is a standard HTML5 video element using either the src attribute or source elements, and the player controls are the built-in controls of the browser.
What my module provides in addition is a playlist which can be used to navigate to sections of the video, display of loading or seeking status and the possibility to switch between different groups of video sources, typically for choosing different video qualities.
For each of these source groups it is possible to specify multiple video sources to support different video formats.
All parameters are defined in the module's settings, which provide also inline help texts.
There are installable packages available for download, see the releases, and there is an update site for updates.
So feel free to use it.
But there is no documentation yet, and currently I won't be able to provide any support, so you would have to explore on your own how it works.
This might change when I find the time.
