N100s absolutely curb stomp Pis and have very good video hardware encoders/decoders to boot
My cursory research indicates that a low end ryzen would make sense if you are building the board yourself. Right now, I haven’t found a new ryzen mini pc sub 200$. New N100 minis can be had for 150-175$, and if you don’t care so much about power N95 minis are even cheaper.
