Methods
The IMFContentProtectionDevice interface has these methods.
| Method | Description |
|---|---|
| GetPrivateDataByteCount |
Gets the required number of bytes that need to be prepended to the input and output buffers when you call the security processor through the InvokeFunction method. When you specify this number of bytes, the Media Foundation transform (MFT) decryptor can allocate the total amount of bytes and can avoid making copies of the data when the decrytor moves the data to the security processor. |
| InvokeFunction |
Calls into the implementation of the protection system in the security processor. |
