.mp4 support in browser widget--Windows

[Paul Dupuis]

Livecode on Windows (9.x.x and 10.x.x) still uses DirectShow for the 
video (vs the Microsoft Media Foundation (MMF), the current standard. 
DirectShow was always limited in the number of codec for various audio 
and video formats it supported natively. I stringly recommend for macOS 
Windows parity on video formats to install the free library of 
additional DirectShow supported codec that are a part of the LAV Filters 
package. See https://github.com/Nevcairiel/LAVFilters/releases

Just install the current version of LAV Filters and restart and you get 
a whole set of additional audio and video formats supported for Livecode 
for Windows.

In the music application I’ve been developing, we are now going into new, transformational frontiers in education with web-based video (such as YouTube) interacting with normal Livecode—but this works on macOS ONLY. I tested YouTube videos in the widget on Windows 10, and the YT player reports that the videos are unsupported.
