Can anyone suggest which CPU is cost effective for a full-duplex video phone (1:1, not a conference) at 320x240 resolution? The application is not mobile but communication is over 802.11. The OS is Linux and needs a SOC with USB, LCD controller, camera, etc. If the CPU has enough horsepower for video phone it can do the other things it needs to do without problem.
I'm having trouble optimizing CPU cost plus CODEC license fees.
