Overview
Harmony 2ES and 4ES 5
Harmony 4ES Application Interface (API)
The source code for the Harmony Vidserve program is
provided for developers as an example of how to access the
driver. The current version of the driver uses a proprietary C
API interface, instead of a standard interface like MCI or Direct
Show. Applications can use the driver by calling the dynamic
link library,
4REELAPI.DLL. The files needed, 4REELAPI.LIB and
4REELAPI.H, are provided in the Vidserve.ZIP file, along with the
source code and MS VC++ 6.0 project makefile for Harmony
Vidserve.
4REELAPI.H declares all of the functions available in
the driver library.
Refer to the Harmony SDK manual for more information.
Harmony Driver VccReg.exe Editor Interface
The Driver Editor allows the user to access and change the
Harmony API driver parameters. For more information see
Editing Driver Settings on page 45.
