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.
