  - startRecording
```
IDvrStreamStore startRecording()
```
    Request that stream recording start.
    Used internally. Clients should call ILiveStreamDvrRecorder.startRecording(). Note that this call places the DVR stream store in the recording state. If the stream store is in the paused state, DVR recording will not occur.
    If there is not currently a stream store for recording, one will attempt to be created. A successful start will result in registered IDvrRecordingListeners to have their IDvrRecordingListener.recordingStarted(IDvrStreamStore) method called.
    Success only occurs if the stream canRecord IDvrStreamStore.canRecord() and the stream is not already in the recording state.
    
    Returns:
    
    store if successful. null otherwise.
  - stopRecording
```
IDvrStreamStore stopRecording()
```
    Request that stream recording stop.
    Used internally. Clients should call ILiveStreamDvrRecorder.stopRecording(). Note that this call places the DVR stream in the not recording state.
    A successful stop will result in registered IDvrRecordingListeners to have their IDvrRecordingListener.recordingStopped(IDvrStreamStore) method called.
    Success only occurs if the stream is already in the recording state IDvrStreamStore.isRecording().
    
    Returns:
    
    store if successful. null otherwise.
  - pauseRecording
```
IDvrStreamStore pauseRecording()
```
    Request that stream recording pause.
    Used internally. Clients should call ILiveStreamDvrRecorder.pauseRecording(). The stream does not have to be actively recording to be paused. For example, it could be paused before packets start flowing.
    A successful pause will result in registered IDvrRecordingListeners to have their IDvrRecordingListener.recordingPaused(IDvrStreamStore) method called.
    
    Returns:
    
    store if successful. null otherwise.
  - resumeRecording
```
IDvrStreamStore resumeRecording()
```
    Request that stream recording resume.
    Used internally. Clients should call ILiveStreamDvrRecorder.resumeRecording(). The stream does not have to be actively recording to be resumed. For example, it could have been paused before the stream started, and this call would move it out of the paused state.
    A successful resume will result in registered IDvrRecordingListeners to have their IDvrRecordingListener.recordingResumed(IDvrStreamStore) method called.
    
    Returns:
    
    store if successful. null otherwise.
  - loadArchivedStore
```
IDvrStreamStore loadArchivedStore(String vStreamName,
