Facetime Video Calls fail with iSight (firewire)

[bbb555]

I've recently upgraded to Sierra and run versions 16A320 and a clean install of 16A323.
Both versions I haven't been able to do FaceTime video calls.
My setup is a Mac Pro with an external FW iSight camera.
Facetime audio calls work fine - FaceTime recognises when the isight is turned off or disconnect, but fails to display video.
The isight works fine since I can still do video calls using Skype and Lync.
Even Photo Booth still works fine.
Just in the FaceTime app won't display video.

Anyone else had this issue ?
