IMSVidStreamBufferSourceEvent Interface
This topic applies to Windows XP Service Pack 1 or later.
The IMSVidStreamBufferSourceEvent interface is used to receive events from the MSVidStreamBufferSource object.
This interface is an outgoing connection-point interface. To receive events from a playback device, implement this interface and then call the IConnectionPoint::Advise method to establish a connection.
In addition to the methods inherited from IMSVidFilePlaybackEvent, the IMSVidStreamBufferSourceEvent interface exposes the following methods.
| Method | Description |
| CertificateFailure | The object failed to get an encryption/decryption license. |
| CertificateSuccess | The object succeeded in getting an encryption/decryption license. |
| ContentBecomingStale | Called when the stream buffer source lags behind the stream buffer sink. |
| RatingsBlocked | The object has blocked the stream, because the rating is not allowed under the current permissions. |
| RatingsChanged | The current rating has changed. |
| RatingsUnblocked | The object has unblocked the stream. |
| StaleDataRead | Called when the MSVidStreamBufferSource object reads from a temporary recording file that has been marked for deletion. |
| StaleFileDeleted | Called when a temporary recording file is deleted. |
| TimeHole | Called when playback reaches a gap in the recorded content. |
