[AG-TECH] H.264 bittersweet experience.

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

 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.
