Windows 11 will have the issue. Livecode on Windows 10 or 11 uses
DirectShow. Try the LAV Filters to get the formats you want. .mp4 is
fine, I am not sure about .mp5 support. See the LAV Filters read me and
documentation.

Thanks, Paul.
So, Windows 11 shouldn’t have this issue?

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.

Hi, the browser widget doesn’t support .mp4 (or .mp5, both part of the HTML5
standard) in Windows.
This is disappointing, especially as LC 10 becomes web based. 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.
I understand that there is licensing involved. MPEG LA, now VIA Licensing
Alliance, has a fee structure. For hardware decoders, for example:
For the first 1 to 50,000 decoders No Royalty*
For decoders 50,001 and more $ 0.25**

<https://www.via-la.com/licensing-2/mpeg-4-visual/mpeg-4-visual-license-fees/>
Is this an obstacle for LiveCode as software, and dependent on the underlying
hardware?
My understanding from past LC forum posts is, to allow the widget to play the
videos a flag is turned on and the widget recompiled.
I’m happy to pay for the licensing myself if I got to 50K customers!
