The ICCompressQuery macro queries a video compression driver to determine if it supports a specific input format or if it can compress a specific input format to a specific output format. You can use this macro or explicitly call the ICM_COMPRESS_QUERY message.
DWORD ICCompressQuery(
hic,
lpbiInput,
lpbiOutput
);
Returns ICERR_OK if the specified compression is supported or ICERR_BADFORMAT otherwise.
When a driver receives this message, it should examine the BITMAPINFO structure associated with lpbiInput to determine if it can compress the input format.
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in vfw.h.
