About the Video Compression Manager
Typically, installable compressors operate with video-image data stored in audio-video interleaved (AVI) files. This overview explains the programming techniques used to access installable compressors through VCM and covers the following topics:
- VCM and the Video for Windows architecture
- Compressing and decompressing image data from your application
- Using VCM renderers to draw data from your application
- VCM functions and structures
Before you read this overview, you should be familiar with the Microsoft Win32 graphic services. In particular, bitmaps and bitmap-related structures, such as BITMAPINFO and BITMAPINFOHEADER, are used extensively by VCM. For additional information about the BITMAPINFO and BITMAPINFOHEADER structures, see Bitmaps.
