[PATCH v3 0/5] MR6442: winedmo: Introduce a new DLL as a MF FFmpeg backend.

[Rémi Bernon]

This introduces a new alternative FFmpeg-based implementation for the
MF byte stream handlers, while keeping the current GStreamer-based as
default.

The new implementation can be enabled by setting the DWORD value:

  DisableGstByteStreamHandler = 1

in the HKCU\Software\Wine\MediaFoundation registry key.
