/** \defgroup avi AVI - Windows Audio-Video Interleaved RIFF
* \section Description
*
* \par
* Windows Copyright Microsoft Corporation.
* \par
* Access to the AVI format uses Windows AVIFile library. Available in Windows Only. \n
* When writing a new file you must use an ".avi" extension, or the Windows API will fail. \n
* You must link the application with "im_avi.lib"
* and you must call the function \ref imFormatRegisterAVI once
* to register the format into the IM core library.
* In Lua call require"imlua_avi". \n
* Depends also on the VFW library (vfw32.lib).
* When using the "im_avi.dll" this extra library is not necessary. \n
* If using Cygwin or MingW must link with "-lvfw32".
* Old versions of Cygwin and MingW use the "-lvfw_ms32" and "-lvfw_avi32".
* \par
* See \ref im_format_avi.h
