Hi,

I am using the GPU Intensity Pro on a 64Bit Windows 7 Enterprise HP Desktop Computer at work together with Sony HDR-CX570 camcorder.

The Microsoft Lync 2013 Basic Client 32-bit version 15.0.4.4701.1000 is used with the latest patch KB2956174.

I have connected a video signal to the Intensity Pro and I would like to use this input in Microsoft Lync 2013 for video calls. BUT I have NO VIDEO signal in Lync.  In Lync Options->Video Device settings->Select the camera you want to use for video calls (Declink Video Camera is used). The preview window in Lync is always black i.e. there is no video input signal from camera. In video conference call there is NO VIDEO, too. The GPU drivers used are latest Blackmagic's Desktop Video 10.4 drivers for the Intensity Pro.

The Intensity Pro drivers are working properly because when I use the Blackmagic Media Express utility I can see preview video from the camera and I can change the video resolutions through graphic cards properties   no problem at all. I use the direct input from a camera and it works.

The Intensity Pro is shown in the Device Manager and no errors at all.

Within Lync I can access to change the video settings but the changes are not accepted and the small screen is still black. So please let me know how to fix the problem.

Hi,

Did the issue still happen if use the computer default camera?

Check if another program on your computer is using the camera. If so, close that program and try again.

Please also test using another computer.

Hi,

The issue didn't happen with e.g. Logitech Webcam C270 connected over USB port. It always works on any PC and Lync 2013. The preview and conference call with Lync works properly.

There are no other applications running and using the camera.

I have tested the configuration Sony-GPU (Blackmagic Intensity Pro using HDMI cable)- Lync 2013 on four different desktop computers with the same procedure and result is partially successful:

1.) 2 PCs - Lync preview - NOK (black screen preview)

                - Lync conference call - OK - during Lync video conference call other side can see my video and I can see self preview on main screen.

2.) 2 PCs - Lync preview - NOK (black screen preview)

                - Lync conference call - NOK - during Lync video conference call other side cannot see my video and I cannot see self preview  (black small screen) video on main screen.

Best regards,
