Why won't my Custom SDK Applications from Video Savant 3.0 work with Video Savant 4.0?

Video Savant 3.0 and Video Savant 4.0 are two different programs and while their SDKs functions are similar, each program has it's own version of vssdkvc.lib that is specific to the version of Video Savant that it is built for and there are differences in the header files. When porting an SDK application from Video Savant 3.0 to Video Savant 4.0 you must rebuild it with the Video Savant 4.0 header files and libraries. Some function prototypes may have changed, some functions will have been renamed and some functions may have been removed if they are no longer appropriate for Video Savant 4.0. When you rebuild your Video Savant 3.0 SDK application with the Video Savant 4.0 SDK it is recommended that you look up the Video Savant 4.0 documentation for each Video Savant SDK function that you use in your application.

Why Can't I use my Video Savant 3.0 Stream Filters with Video Savant 4.0?

Video Savant 3.0 Stream Filters are not the same as Video Savant 4.0 Stream Filters. While many of the functions that you define have the same names and parameters, the calling conventions are different. When porting a Stream Filter from Video Savant 3.0 to Video Savant 4.0 you must update the definition of every Stream Filter function from the Video Savant 3.0 definition to the Video Savant 4.0 definition. In all cases this includes adding the PASCAL keyword to the function definition, but many other functions have changed. You should look in the Video Savant SDK Guide for the updated definition of each function that you define in your Stream Filter.

Why Can't I build Video Savant SDK applications with Borland C++ Builder?

The Video Savant 3.0 SDK includes a library to build SDK applications with Borland C++ Version 5.01, but not Borland C++ Builder. Borland C++ Builder is not related to the older Borland C++ and libraries built with Borland C++ cannot be linked to Borland C++ Builder applications. The library file "vssdkbc.lib" is for Borland C++, not for Borland C++ Builder. If you need to build a Borland C++ Builder application for Video Savant 3.0 contact IO Industries to obtain the library file vssdkbcb.lib. The Video Savant SDK Library vssdkbcb.lib exists for Video Savant 4.0 as well, but the Borland C++ library vssdkbc.lib does not.
