The ICM_DECOMPRESSEX_END message notifies a video decompression driver to end decompression and free resources allocated for decompression. You can send this message explicitly or by using the ICDecompressExEnd macro.
ICM_DECOMPRESSEX_END
wParam = 0;
lParam = 0;
Returns ICERR_OK if successful or an error otherwise.
The driver frees any resources allocated for the ICM_DECOMPRESSEX_BEGIN message.
ICM_DECOMPRESSEX_BEGIN and ICM_DECOMPRESSEX_END do not nest. If your driver receives ICM_DECOMPRESSEX_BEGIN before decompression is stopped with ICM_DECOMPRESSEX_END, it should restart decompression with new parameters.
