ICM_SETSTATE
The ICM_SETSTATE message notifies a video compression driver to set the state
of the compressor. You can send this message explicitly or by using the ICSetState macro.
ICM_SETSTATE
wParam = (DWORD) (LPVOID) pv;
lParam = (DWORD) cb;
Parameters
pv
Address of a block of memory containing configuration data. You can specify
NULL for this parameter to reset the compressor to its default state.
cb
Size, in bytes, of the block of memory.
Return Values
Returns the number of bytes used by the compressor if successful or zero
otherwise.
Remarks
The information used by this message 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 the ICM_CONFIGURE message to adjust the configuration of a video compression driver.
