Windows - Gem video not loading
On Windows it's not possible to load any video (any codec). There's a post on the forum with more information. The problem is also on Windows 10.

It appears that even with the latest Gem on Windows, the DS backend being used there won't load any common video files. I have the same issue, but I haven't had the time to look into it, much less a solution. There must be a way to get this working, DS is supposed to handle all those formats.
The backend that does work (at least in Gem 0.93), is Quicktime (QT), but that's tricky to build (IIRC because of licensing issues the required Windows library can't be included, and I'm pretty sure that there's no libquicktime in msys2 either). I actually had the QT backend working with 32 bit vanilla at least, using some binaries of Gem 0.93+git-something I found on the web somwhere. I think that this is what the post cited by @eeight is about.
FWIW: Here, a GEM maintainer suggested to install the K-Lite Codec Pack.
After doing so, [pix_film] was able to load MP4 (h264 encoding) with no problem in Pd-vanilla and Purr Data on Windows. (I didn't test other encodings because h264 runs the world now.)
Is this the solution? Well, I'm not sure... it worked for umlaute@github and it worked for me, and it would probably work for most users. I don't know if it's guaranteed to work on every system.
But at least it suggests that the problem isn't GEM doing something fundamentally wrong. It seems more likely that it's unable to use whatever codecs that Windows Media Player or VLC have access to.
Edited by H. James HarkinsIs this the solution?
- it has a "freeware" license that means I can't and won't ship it (plus I'd rather not suggest to install it to users)
- it isn't in msys2 (probably for exactly the same licensing reason)
What's the problem with leveraging VLC? It should be able to decode all the things.
