How many NVDEC sessions are supported?

There is a table here ( ) that tells how many ENCODER sessions are supported. But it does not tell how many DECODER sessions are supported on different platforms. Does anyone know? Is there any way to figure this out? I understand that this might depend on frame size - but then again maybe (like the encoder) it does not… There is simply no information available anywhere as near as I can tell.

Related to that is there anything I can do to maximize the number of sessions on a given hardware platform?

(I write video surveillance software supporting large numbers of cameras so this is an important topic for me!)
