.mp4 support in browser widget--Windows

[Peter Bogdanoff]

OK thanks.

Many of our users are college undergrads, some of which appear to have never installed an application on their own computer. Now I have to get them to do a second installation as well.

By any chance, can I get my LC application to initiate the LAV filters install?

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

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.
