- Two or more Blackmagic USB3 or PCI cards, either HDMI or SDI.
The PCI cards need Blackmagic's own drivers installed. The USB3 cards
- are driven through the “bmusb” driver embedded in bmusb/, using libusb-1.0.
- If you want zerocopy USB, you need libusb 1.0.21-rc1 or newer,
- as well as a recent kernel (4.6.0 or newer). Zerocopy USB helps not only
- for performance, but also for stability.

The patches/ directory contains a patch that helps zita-resampler performance.
It is meant for upstream, but was not in at the time Nageru was released.
