AVIFile Reference

  • Article

[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 It has been superseded by Source Reader.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.]
