The most likely reason for IDeckLinkInput::EnableVideoInput returning E_FAIL, is that the input resource is already tied up, either:
- The input has been enabled by another process, or
- The device is configured for half-duplex profile and the output is enabled. You can check the active profile by running the ActivateProfile SDK sample
