Context & Problem:
- I want a way to serve an AviSynth media stream into NLEs etc., e.g. Sony Vegas. I have done this for years under Windows XP-SP3 (32-bit).
- Partly just for the flexibility of having this option.
- Partly (as explained at http://blog.davidesp.com/archives/388), as a workaround to another problem with old software under Windows 7.
- However an attempt at installation in Windows 7 failed – because (I now know) the installer is obsolete (and hence incompatible) with respect to Windows 7.
- VFAPI requires to be installed, via .bat/.inf files, so that for example it appears in the Registry.
- But the installer fails under Windows 7. It is compatible with XP but not Windows 7 (or Vista).
- It is possible to manually “hack-install” VFAPI into Windows 7, but that causes me anxiety…
Possible Solutions:
- Possibly the tricks reported at http://www.sonycreativesoftware.com/forums/ShowMessage.asp?ForumID=4&MessageID=750967 (which in any case is a great article about motion-estimation-based slow-motion in AviSynth) might get VFAPI working on my W7 system.
- Or there may be a better way…AVSP
- Instead, use AVFS – AviSynth Virtual File System: http://avf.sourceforge.net/
- To simplify life, there is a single download (zip file) of a suite of apps & plugins associated with AViSynth at http://www.animemusicvideos.org/guides/avtech3/amvapp.html. This suite used to include VFAPI and now instead includes AVFS.
