[gst-devel] gst directshow wrapper weirdness

[Ali Sabil]

Hello again,

Now I finally managed to fix the stdcall symbol naming problem (the @x
that get appended), by making use of Aliasing (both symbols are
available now), now Regsvr32 succeeds, but I still get this error saying
that it failed at creating the FakeSink filter.

Any help/idea/suggestion would be very welcome.

Thanks
