![]() ![]() I have a 1080p signal hooked up to the input and a 1080p monitor hooked up to the output (loopthrough port on the decklink card). I have a Decklink 4K Extreme card with an nvidia quadro M5000 in an HPZ820.ġ.) When I run LoopThroughWithOpenGLCompositing.exe from the SDK, I get an "Expected both Input and Output DeckLink devices" error on initialization. I'm interested in getting this working at well. Let me know if this doesn't seem doable with GPUDirect. My actual application simply needs to access the frame buffer of the video card and output it directly to a decklink SDI output. Is that part of the Cuda tools, or possibly NVIDIA's OpenGL toolkit? Can you tell me where to find the DVP library? ![]() It's not clear where I find the DVP library. The BMD SDK docs indicate "GPUDirect support requires the use of the DVP library supplied by NVIDIA." ![]() I'm trying to make the LoopThroughWithOpenGLCompositing work on Linux with a Quadro K4200 card. Blackmagic desktop video sdk how to#If you are using Direct x11 then, please let me know and we can determine how to support your needs. The sample is called "loopThroughWithOpenGL compositing". Blackmagic Design does provide sample application and the code for this sample which you can modify in the SDK download via the OS folder and samples. The function is supported via OpenGL and at this time, there is no support for a CUDA transfer between the GPU and the video input / output device. GPU Direct is supported on Windows 7/8 64bit and Linux 64 bit using our SDK, current driver from BMD (10.4) and current Quadro card from NVIDIA equal to 4xxx and higher models 5xxx and 6xxx. You can register and download the SDK and manual by going to our support page, select capture and playback products, and then scroll down in the lower left most area to see available downloads.ĭesktop video or the DecklinK SDK supports all capture and playback including Ultrastudio, Intensity and Decklink products. The information for GPU Direct for video with Blackmagic Design capture and playback products is in our desktop video products SDK document. ![]()
