ICM_COMPRESS_GET_FORMAT

See also ICM_COMPRESS_QUERY, ICM_DECOMPRESS_GET_FORMAT

wParam = (DWORD) (LPVOID) lpbiInput;
lParam = (DWORD) (LPVOID) lpbiOutput;

Requests the output format of the compressed data from a video compression driver.

• Returns ICERR_OK if successful or an error otherwise.

wParam

Address of a BITMAPINFO structure indicating the input format.

lParam

Address of a BITMAPINFO structure to return the output format. You can specify zero for this parameter to request only the size of the output format.

If lParam is nonzero, the driver should fill the BITMAPINFO structure with the default output format corresponding to the input format specified for wParam. If the compressor can produce several formats, the default format should be the one that preserves the greatest amount of information.
