Video Compression Manager

[The feature associated with this page, AVIFile Functions and Macros, is a legacy feature. It has been superseded by Source Reader. Source Reader has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader instead of AVIFile Functions and Macros, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The video compression manager (VCM) provides access to the interface used by installable compressors to handle real-time data. Applications can use installable compressors to perform the following tasks:

  • Compress and decompress video data.
  • Send a renderer compressed video data and have it draw it to the display.
  • Compress, decompress, or draw data with application-defined renderers.
  • Use renderers to handle text and custom data.

This overview covers the following topics.
