Decklink SDI with SDK 10.6.5

Hi
Just starting out with BM development using a Decklink SDI card.
Trying to get the SignalGenCSharp sample to work with this with no success.

Its tripping up when setting the video output mode. Can anyone tell me if this card actually supports m_deckLinkOutput.EnableVideoOutput ?

The code is erroring with
"An unhandled exception of type 'System.UnauthorizedAccessException' occurred in SignalGenCSharp.exe

Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))"

cheers
Malcom

Bump

Doesn't anyone from BM read these forums?

Hi Malcom,

Please note that these are primarily user forums, please see the SDK Manual section "1.2  Overview" which provides an email address for direct developer enquiries.

The DeckLink SDI does support video output, but please note that the mentioned device is a half-duplex device - capable of capture and playback, but not both simultaneously.

EnableVideoOutput[1] may return E_ACCESSDENIED if it is unable to access the hardware - including if the device is already in use.

Please check if another application (possibly a previous instance of the same application) is not already using the device.

Cheers,

Thanks Nick

Yeah I thought that but the card is not being used by any other code. Several PC reboots just in case.
Have borrowed a SDI 4K card which works fine but the older SDI does not.
Would have liked to use the SDI as I do not need duplex.
