Automatic registration of codecs from the "vfwcodecs" folder

To successfully open AVI files using the "Audio/video interleave input driver (internal)," you need VFW codecs.

It's best to install these codecs on your system. However, VirtualDub2 v2.5.3 now allows you to temporarily register codecs from the "vfwcodecs" folder (the Lagarith and Xvid codecs are included).

There are some restrictions for registering codecs from the "vfwcodecs" folder:

1. The codec architecture (32 or 64 bit) must be the same as VirtualDub2.
2. The total path to the codec file must not exceed 128 characters.
3. The path must not contain spaces.
4. Additional DLLs must be placed in the VirtualDub2 folder (the same location as VirtualDub2.exe).

This method isn't universal. Some VFW codecs may not work for unknown reasons.
