[SOLVED] QCamera, WDM Streaming and DirectShow



  • Hi everyone!

    I have BlackMagic DeckLink Quad card for capturing video stream from SDI. And I want to capture it from application writtent with Qt. And I have a question: can QCamera capture WDM Streaming video? Or I should use something like DirectShow?

    Thanks for helping!

    PS. There is no DeckLink in QCamera::availableDevices().
    PS2. How to connect DirectX SDK to QtCreator?

    Hi and welcome to devnet,

    AFAIK it's normal that you don't have the 4 devices listed as cameras, technically these inputs are not cameras.

    What you can do is use the DeckLink SDK. BlackMagic provides a pretty good SDK that is cross-plaform and Qt friendly (look at their examples. they use Qt)

    Hope it helps



  • Thank you very much! I didn't know that there is DeckLink SDK, I thought, that DeckLink has only WDM drivers and DirectShow Filters.

    Have a good day, happy New Year and thank you again!
