The PCI cards need Blackmagic's own drivers installed. The USB3 cards
are driven through the “bmusb” driver, using libusb-1.0. If you want
zerocopy USB, you need libusb 1.0.21 or newer, as well as a recent

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.
It is taken to be by Steinar H. Gunderson <sesse@google.com> (ie., my ex-work
email), and under the same license as zita-resampler itself.

it will make the USB3 threads do so, which will make them a lot more stable.
