Hello Herr Kost,

So, If I understand your response, VST plugins compiled for Windowx/MacOSX
would need to be recompiled to run as plug-ins using Gstreamer.

Wine just give a Windows emulation for x86 emulation I gather.

Our software manager has decided to build our Dolby, DTS, etc. plug-ins to
use Gstreamer as interface which I believe is fine, I just need other VST
applications to be ported to Gstreamer.

I wish I had some quick way to evaluate Gstreamer plug-ins versus VST
approach. Perhaps this will take some effort to gather benchmarks on
latency.

Danke fur alles
