As video live input cards we implemented several input cards directly via the SDK.


Integrated Live Input Cards:

Deltacast:

  • Deltacast 3G-elp-20, BNC PCI Express Capture Card
  • Deltacast 3G-elp-40, BNC PCI Express Capture Card
  • Deltacast 3G-elp-d4C PCI Express Versatile I/O Card
  • Deltacast 3G-elp-d8C PCI Express Versatile I/O Card
  • Deltacast h4k2-elp 20 PCI Express Capture Card (2xHDMI2.0)
  • Deltacast 12G-ELP-H4C
  • Deltacast 12G-G1C-HDMI


Datapath:

  • VisionSC-DP2
  • VisionSC-UHD2
  • VisionSC-SDI4


Blackmagic:

  • DeckLink Quad HDMI Recorder
  • Decklink 8K Pro




In principle, however, any input card that works via DirectShow can be used in Pixera.
