ICM_DECOMPRESS_END message

  • Article

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;

Return Value

Returns ICERR_OK if successful or an error otherwise.

Remarks

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.
