Sebastian Dröge d61b415230 Add properties for selecting capture/output frame buffers to use 
And calculate them automatically be default based on the number of frame
buffers available and the number of channels.

This works around various bugs in the AJA SDK when selecting these
manually.

See AJA support ticket #5056.
