Build issue on Windows

[jebej]

Seems similar to issue #27 but the message is not the same:

There might be some kind of conflict with VideoIO

I'm also seeing a build error in Windows, not sure if its related:

I'm having the same issue with a different file.

Same issue with v0.4.0 and v0.3.0 on Windows:

I have to downgrade to v0.2.4 and it finally worked. In v0.2.4, FFMPEG is locally builded when installing by Pkg, so I would presume that a broken 'artifact` is uploaded.

[giordano]

Please update the registry, it should work now

[giordano]

@dlfivefifty FFMPEG cannot possibly work on Travis due their installation of Windows lacking audio/video system libraries: https://github.com/JuliaIO/FFMPEG.jl/issues/14#issuecomment-537288621. There is nothing we can do, the only solution is to test packages involving FFMPEG on Windows on other CI services, like AppVeyor or GitHub Actions

Many thanks. Now the LoadError is gone ! 😄

[bradcarman]

I'm experiencing this same issue. I'm using v0.4.1. This is on a Windows VM machine. On my host Windows machine FFMPEG v0.4.1 works fine. Note: This is Windows 10 Pro N, the N means media parts are not installed as I understand. Maybe I'm missing some critical media dll that is needed?

I discovered the solution. I suspected some codecs were missing, so I installed the Media Features Pack in Windows and now it's working!
