The ICSetState macro notifies a video compression driver to set the state of the compressor. You can use this macro or explicitly call the ICM_SETSTATE message.
DWORD ICSetState(
hic,
pv,
cb
);
Returns the number of bytes used by the compressor if successful or zero otherwise.
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 ICGetState and ICConfigure macros and should use the ICConfigure macro to adjust the configuration of a video compression driver.
