Grumpy_Mike:
You could try a USB Hub.

Although I doubt if there is enough bandwidth in the system to support two video streams, but I don't know for sure.

And AR9342:MIPS 74Kc@560MHz, 2.4GHz, 5GHz (dual band) v.s. AR9331 MIPS 24Kc@400MHz, 2.4GHz

MIPS32 24 Kc delivers a performance of 1.6 DMIPS/MHz and 3.1 Coremarks/MHz.
MIPS32 74 Kc delivers a performance of 1.93 DMIPS/MHz and 3.48 Coremarks/MHz

AR9342:MIPS 74Kc@560MHz run 2 times faster than AR9331 MIPS 24Kc@400MHz.

Arduino Tian base on AR9342:MIPS 74Kc@560MHz is better candidate for this type application.
