Seems, that today's CPUs are capable of doing full TS decoding without any significant CPU load (for 68Mbit stream with 20 channels it is less than 5% 3GHz CPU). More, sw. decoder is not a small atomic thing, and can do many additional things. If the PID filter is in the kernel in such case, there is a chance, that we've get additional memcpy() etc. > The (performance) difference between driver and software will be little, I > expect. More, we can miss CPU power and increase kernel size. _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
