good work, thanks!

I wonder will component appear, to support FFMPEG engine video playback in Laz... for Delphi such a component exists. it is shareware, about 100$.

Addressed Windows-specific issues to ensure correct operation.
The initial implementation was developed and tested on a Linux environment, and these fixes resolve the problems discovered during Windows testing.

• Fixed libvgmplay for Windows, no longer requires the zlib library.
• Fixes for correct operation in Windows.
• Removed OpenMPT as some cross-compilation issues with the library have not yet been resolved.
• Added libXmp as a replacement for OpenMPT.
