G'day All
Just thought I would post some CPU usage statistics whilst MPEG4
streaming.
I am currently encoding and decoding on a Dell T3400 Core 2 Quad CPU
machine running Fedora 8!
* 3 x Mpeg4 streams as Large
* 1 x DV Stream @ 36 megs a second
Core 1 - 28%
Core 2 - 29%
Core 3 - 46%
Core 4 - 47%
Note: these values change every second, but average usage across all 4
cores is around 40%.
Output on TOP
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
29456 jastest 30 10 202m 19m 6004 R 38 1.0 488:18.97 vic

1482 jastest 30 10 94784 31m 7312 R 33 1.5 18:18.08 vic
1486 jastest 30 10 94664 30m 7316 S 33 1.5 17:11.20 vic
2798 root 20 0 419m 55m 13m S 13 2.8 162:08.95 X
I hope this information is useful to some.
Cheers,
Jason.

I've not yet tried MPEG4 (I only update vic t'other day), but I'll give
that a
bash.
Machine is AMD X2 4400+, 2Gb ram, Fedora 8.
