ICM_DECOMPRESS_GET_FORMAT

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

Requests the output format of the decompressed data from a video decompression driver.

• Return ICERR_OK if successful or an error otherwise.

wParam

Address of a BITMAPINFO structure describing the input format.

lParam

Address of a BITMAPINFO structure to return the output format. You can specify zero 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.
