How to enable an MPO video capture device/AB virtual channels in Live View

Enabling AB Virtual channels:

First to enable AB virtual channels we need to import a file called DSMPOVirtualChannelEnumerator.dll.

The file is located in \\192.168.40.6\Development\mp2\Common Files\Test

Before copying and pasting the dll. file first it is wise to close all running instances of Airbox.

The file must be copied to C:\Program Files (x86)\Common Files\DMT.

After that the file must be registered in CMD using the regsvr32 command.

If you check Airbox you should have the channels enabled in Software Streaming Devices.

Enabling MPO Video capture device:

In the exact same folder: \\192.168.40.6\Development\mp2\Common Files\Test are located two files:
MPOVideoCapture.ax
LiveInputsEditor
From there we import them into: C:\Program Files (x86)\Common Files\DMT.

We unregister the old versions if they are any using the regsvr32 /u command in CMD.

You can also rename the older manually by typing or using the ren command in CMD.

The renaming is necessary convention, because if the newer versions are corrupted, we can easily revert back the old ones that are working.

The newly imported files must be registered so we can use they're implementations in the software e.g. Airbo

Finally we should have the following options:
