decklink-01The nablet DeckLink Capture Filter allows to reuse a single DeckLink SDI capture port in multiple DirectShow processes. This is especially useful when transcoding from one DeckLink SDI port to different formats where each transcoder graph is running in a separate process. The original Blackmagic DirectShow capture filter doesn’t offer this capability; you cannot even use multiple instances in the same graph.

Features

  • Up to 32 processes and more can share one single SDI capture port
  • Video and audio capture can be mixed in any configuration in multiple processes
  • High stability even when the CPU load exceeds 90% and higher
  • The capture filters can run as slaves using external command-line master without GUI
  • Multicore CPU systems with 16 processors + HT are supported
  • The capture filter can safely detect format changes and re- and disconnecting SDI devices
  • Full low-level integration into nablet’s MediaEngine (under development)
  • This diagram shows the shared SDI port for transcoding
