ever heard of 3ivX?

take a look here for more info..

could it be current DivX players aren't optimized at all? if so, could we see a major performance increase in it?

I'm wondering this, because currently I have a K6-2 400 as my main machine (hey it does the job nicely), and I highly doubt I'll get any good quality DivX videos to play well on here. could 3viX be the answer?
 
As long as the horizontal resolution of the movie is less than 704 (i.e 640, 512, 352) you should be fine with your system. Just kill all other apps running in the background and set the CPU usage slider to 0.

I haven't heard of 3ivX, but DivX is just the MS MPEG-4 codecs with 4 bytes hacked. The MS implementation of MPEG-4 is decent and seems to beat most other implementations. However, one that it does NOT beat (IMHO) is Apple's implementation, which is actually the latest version of QuickTime (but probably with their own tweaks). Anyways I got a 640x480 movie trailer that only gave me 9% CPU usage on a P3-800 and it looked GREAT. Or it could just be QT has some better encoders.

Anyways it's possible that if an open source group comes out with their own MPEG-4 codec, it could be better than Microsoft's, but that would certainly render all current "DivX" files unplayable because they depend on the MS codec, and wouldn't be able to play on anything else without utilizing "DivX" code - which as I said before, is a hack of Microsoft-owned DLLs.

It seems as if MSFT is completely ignoring the DivX trend, probably because it doesn't intrude on any of their core businesses, but if they wanted to, they could file a lawsuit against Gej and everyone else involved in DivX. (The same way Fraunhofer is going after everyone who makes MP3 encoders, saying that THEIR code is in EVERY mp3 encoder, since they effectively invented it - or so they claim).
 
hmm.. ok, but I heard some people mentioning a quality slider in media player (I'm assuming they're using a DivX plugin for that).. they said that even 1ghz Athlons can't play full speed with that at the max.. is that true?
 
The quality slider is what I'm referring to when I say CPU usage slider. Basically it dictates CPU usage of the output "filter".

Anyways, what you are saying is true if the DivX file is encoded at 720x480. That is a very high rez and I doubt an Athlon 1.1GHz could handle CPU usage of 4 with that, since my P3-800 can barely handle 2.

Basically Microsoft's MPEG4 (DivX) has a weakness to resolutions greater than 640x480. At 640x480, my processor can handle CPU usage of 4 unless there is a HELLUVA lot of action - so I usually keep it at 3 and everything is cool (although I won't get much RC5 blocks done while watching the movie 😉

For movies that are 512x384 and lower... I can keep it at 4 and usually only incur 50% CPU usage MAX. So I think you are okay with a K6-2 400mhz, just stay away from the 720x480 flicks. Smart people who rip DVDs to DivX make sure they RESIZE them. 😉
