Though a quick search through online forums suggest that module isn't compiled into Ubuntu's version of VLC by default, so you may need to compile your own version:

Edit: Just checked because I was curious. The default installs of VLC do not include Blackmagic support but you can compile versions from the source for Linux that include it (if you also download the support files from Blacklink first).
Big productions can afford Decklinks and media servers like Disguise D3.
So long as they keep NDI Tools free. It would be great if they could also eventually build in some of the functionality of Dante (NDI is something like Dante but for video) since the Dante software toolkit is very much not free. I think Newtek has been on the right track.
Indeed, we use three of the Flex 4K Out boxes to three projectors doing alpha blending to form a single virtual screen via ProPresenter and it works great!
Especially since someone donated an M1 Mac Mini, not realizing it only supported two traditional external monitors. With NDI we could have an external monitor for the operator display then let ProPresenter generate three virtual monitors via NDI. We can send differently formatted "screens" via NDI to our OBS computer for streaming too - different configurations of lower thirds for texts, full screen mirroring of the main presentation display - whatever we need. NDI really works a treat and I will NEVER go back to analog video again!
We also use the Birddog NDI PTZ cameras for streaming and some crude IMAG too - it's amazing how well NDI works.
Maybe some of those guys scraped together enough money to buy one of the new macbooks (since it got HDMI back). Being forced to spend another $200 to get rid of a stupid orange dot would really sting.
Of course, I'm also confident that software workarounds will exist in the meantime.
edit: looking at your updated post, it is called a "playback card."
This way, you know EXACTLY what the program is computing, nothing else.
Also what’s the use case where they can’t export the video and transfer it as a file or byte stream?
Use case: live (minimizing latency), no compression, compatibility with other gear.
The cheapness of greenscreen effects makes it pretty cheap to use in TV shows a lot these days though.
I think the migration costs (including the learning curves) might seem like a poor tradeoff.
