The ICM_DECOMPRESS_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 ICDecompressEnd macro.
ICM_DECOMPRESS_END
wParam = 0;
lParam = 0;
Returns ICERR_OK if successful or an error otherwise.
The driver should free any resources allocated for the ICM_DECOMPRESS_BEGIN message.
ICM_DECOMPRESS_BEGIN and ICM_DECOMPRESS_END do not nest. If your driver receives ICM_DECOMPRESS_BEGIN before decompression is stopped with ICM_DECOMPRESS_END, it should restart decompression with new parameters.
Windows NT: Requires version 3.1 or later.
Windows: Requires Windows 95 or later.
