Hyperion on windows - USB Capture settings N/A

Hi.
I'm running latest hyperion.ng (2.0.0-alpha.8) on windows 64-bit. Installed using the .exe from github.
Platform capture works fine, but not USB capture. I have tested the USB capture card in VLC and it shows up.
In hyperion web ui, under Capturing Hardware > Instance Capture I can tick the Enable USB Capture box and save.
But below that, Platform Capture settings appear as normal, but the whole USB Capture settings section is missing.
I have a test install running on a spare rPi and the USB capture settings appear normally there, but this was installed using the hyperbian image and perhaps I am missing something for the same in windows...
Have I missed a step to install/enable this section?
Is this function available in Windows? Or is this an anomaly/bug?

Appreciate any pointers.
Many thanks

I found, maybe, an answer buried in a thread about librELEC...

@Awawa made a new release with this missing library but thank you for the clarification.

I want to ask you a question @Paulchen-Panther

When can we will expect USB capture on Windows release ? Or maybe it’s not on the planning ? Or not possible ?

Thanks

If anyone (possibly myself) decides to start implementing for Windows.

All functions under Linux and Windows should already work

No

I'm guessing then it's not implemented yet?
