Methods > Init and info > InitRecordingSystem method

Remarks

Initializes the control: the call to this method is mandatory and must be performed before calling any other method that will use a recording related functionality, possibly in the container form initialization function: calling this method inside the constructor function of the container form will not work and could cause unpredictable results.

If the multimedia engine shouldn't find any enabled or valid input or output device, the container application would be notified through the WarnNoInputDevice and WarnNoOutputDevice events.
