IStreamBufferSink2::UnlockProfile method (sbe.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
The UnlockProfile method unlocks the Stream Buffer Sink filter's profile. After the profile is unlocked, you can change the name of the stub file.
Syntax
HRESULT UnlockProfile();
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The profile is not currently locked. |
|
The method succeeded. |
Remarks
The filter graph must be stopped when you call this method. If the recording session has not been started, this method invalidates the recording. To re-create the recording, call IStreamBufferSink::LockProfile again. If the profile is not already locked, the UnlockProfile method has no effect and returns S_FALSE.
If the graph is running, stopping the graph automatically unlocks the profile without the need to call UnlockProfile.
