Blackmagic cards

Blackmagic cards are an option to capture high definition contents, both camera and laptop sources. Depending on the card installed and the input type you should be able to configure it following these instructions.

Driver installation

Note: The project concerning gstreamer plugin for 10.10 has been discontinued and the plugin has been included in an official gstreamer package. We recommend upgrading to Ubuntu 12.04 in order to use Blackmagic cards.

Blackmagic has partial support for Linux. To install their driver you should download the latest one on:

Choose Linux, your card series and your Model and press Search. Download the latest Desktop Video for Linux.
To install it, run as root the following commands:

apt-get install libjpeg62
dpkg -i <name_of_driver_package.deb>
modprobe blackmagic

There is a full guide on how to install the driver and other information on:

Check if the driver and the card are loaded and ready

Run on a terminal:

lspci | grep Blackmagic
lsmod | grep blackmagic
ls /dev/blackmagic/*
