I disagree.

This is more flexible, and allows to have the module selectable
in the UI, in a relevant way.

Moreover, if the Dx-runtime is reinstalled, it will work directly,
without needing to nuke the VLC plugins cache.

We do that with ALL DirectX related libraries, DSound, DDraw, D3D, DxVA,
D2D1, as recommended by MicroSoft.
