DivX encoding issues on hyperthreading cpu

bibibobo

anybody know why my hyperthreading cpu is only running at 50% when encoding divx video? should dr divx not be grabbing ~100% of the cpu??

Maybe it doesn't need to use 100%, maybe you don't have enough ram to process the information, maybe your hard-drive is too slow to load in the data. Who knows.

And I'll assume the Divx's you're encoding are legal. If they're not, I'll lock this.

I agree tbh.

I would have thought Dr. DivX should use 100% of cpu. If ur pc has a decent spec all round then there should be no problem.

What was a bit much? If you don't have anything of use to contribute, then don't.

whats with the threat of heavy handed moderation? - or am i reading this thread correctly.
anyway, i switched hyperthreading off in the bios and now dr divx is using 100% cpu so goodbye hyperthreading feature until divx issue a fix.

I like to warn people.

Ok,

i've finally given up on encoding my DVD's to DiVx, reasons:

1. take way too long (up to 3 hours!!!)
2. resultant file often has video and audio incorrectly matched (couldnt be arsed trying to correct in the likes of virtualdub etc). anyway the sound is mismatched at the end of the video rather than the beginning further complicating the correction task.
3. my new philips 630 divX player plays the files ok but has a crappy interface and aint the quickest to load.
4. divx encoder costs $20

I think the main reason i tried divx out is to have the ability to store dvd's on my pc (wouldnt be watching them on the pc though) as backups.

Conclusion:
I now DVD shrink all my DVD's and burn to cheap media DVD-R/+R as back-ups for the original disks which I own.

Divx Sucks!!!

Edited for Legal reasons.

hehe, im so tempted to say pms, but i won't

i've encode with divx and xvid on a 3.09 hyperthreaded p4 and have noticed absolutely no difference (timewise) between encoding with it on and with it off, come to think of it i don't think i've ever seen one application go above 50% cpu time with it on and there's no performance loss, actually with it off the pc slows to a crawl when an app takes up 100% cpu time

do a test, encoded something, say a minute long, with ht on and with ht off and tell us if theres any difference in the time it takes

It's not CPU usage you should be looking at but fps. Personally I wouldn't want anything using 100% of my CPU. I encode on Idle and leave it in the background while I do whatever I want. Doesn't bother me too much how long it takes.

Use xvid and Gordian Knot. Been encodeing things for years now and have never had to pay for the software or had mismatched audio/video
