Decklink SDI

Decklink SDI, vinput, ainput' name='keywords
Flussonic can capture video directly from a Decklink SDI or HDMI capture card.

You need to install Blackmagic drivers, update the card and then configure the stream as follows:

stream sdi {
  url decklink://0 enc="vb=1024k preset=superfast tune=zerolatency ab=32k";
}

Flussonic Media Server will take the first device (0) and use its autoconfiguration feature to capture video (search for active resolution).

Some Decklink models do not support automatic search for active resolution, and for those models you'll need to specify it manually by using the options mode and vinput. For example, if you have Intensity Pro with connected HDML source of 720p at 50 fps, you should configure it as follows:

stream sdi {
  url decklink://0 mode=hp50 vinput=3 external=true enc="vb=3096k ab=64k";
}
