lParam = (DWORD) cb;

Notifies a video compression driver to set the state of the compressor.

• Returns the number of bytes used by the compressor or zero to indicate an error.

wParam

Address of a block of memory containing configuration data. You can specify NULL for this parameter to reset the compressor to its default state.

lParam

Size, in bytes, of the block of memory.

The information used by ICM_SETSTATE is private and specific to a given compressor. Client applications should use this message only to restore information previously obtained with the ICM_GETSTATE message and should use ICM_CONFIGURE to adjust the configuration of a video compression driver.
