Presumably not what Russell is asking for, so OT but interesting anyway ... the
paragraph under those big letters:

"DeckLink cards are open standard capture cards and are perfect for the
development of Linux based video applications. The availability of a free, well
documented SDK makes it easy for you to develop specific solutions to meet your
needs, or to work with solutions that have been developed by others.
Blackmagic’s Design Media Express is also available for capture and playback
when using DeckLink with Linux operating systems."

So they seem to have open low-level access. Their mixers and switchers for
serious $$$ are built on embedded RT systems (controlled from hardware panels or
from remote software) but they don't say what kernel they are using. Their
colour/editing software DaVinci Resolve is available in Linux. That is exactly
what has been very useful in the past for me ... hardware sold by a company
which also sells commercial Linux based solutions. They are well motivated to
maintain the drivers for the devices they use, and they have the budget and
skills to do so. But their main customers have real budgets to, the gear is
expensive, but these two could be useful if you have the cash:

analogue, sync, SDI, more serious multi-channel audio, keying etc: $700-ish

analogue video, much more basic audio etc: $250-ish ...

    (the thunderbolt and USB3 versions are not for Linux, only the PCIe)

The standard log and capture and playlist software is included with the
hardware, and is Linux compatible ...

So all quite interesting, I haven't looked at this stuff for a while and it has
got much much less expensive, smaller and more powerful than it was a few years
ago (not surprisingly).
