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.
Note The audio compression manager (ACM) provides system-level support for audio
compression and decompression drivers. For a description of the audio
compression services, see Audio Compression Manager.
