S_OK

Remarks

By default, quality control is disabled. With quality control disabled, the DMO delivers every sample.

With quality control enabled, the DMO attempts to deliver samples on time. It can skip late samples if necessary.

If you enable quality control, call the IDMOQualityControl::SetNow method to specify the earliest time stamp that the DMO should process. Otherwise, the call to SetStatus succeeds but the DMO does not perform quality control.
