Description

Specifies a content key in a call to the VideoDecoderBeginFrame function.

Members

`hOutputView`

A handle to the driver's private data for the video decoder output view. This handle was created through a call to the CreateVideoProcessorOutputView function.

`pContentKey`

A pointer to a content key that was used to encrypt the video frame data. If no content key was used, set this member to NULL. If the caller provides a content key, the caller must use the session key to encrypt the content key.

For more information, see the VideoDecoderBeginFrame function.

`ContentKeySize`

The size, in bytes, of the content key that is specified in the pContentKey member.
