Xvid and multipros

[beber75]

Hi, i'd like to test (and use) the xvid multiproc codec but i couldn't find them.
The only site that is talking about is "uManiac's place" but the file is always missing.
Could somebody provide me a valid link where i could download them?

XivD smp is broken in the last versions.
and it was _very_ experimental !!!
(buggy, slower, ect...)

but when B-frames would be finished (in some years ;))
smp would allow to code 2 b-frames in parallel, so there would be more interest in the thing.

I wonder if this would really speed up things. Usually you're not only encoding, but in case of dvd ripping decoding and resizing as well which should, as I understand multiproc systems, be all distributed among the processors.

The encoding can be done in several threads, which use more processors and speed up things in a MP environment.
The thread overhead slows down encoding on a single processor system though, so it's not advisable to use a MP build on a SP system.

I started to adopt the SMP code to reflect recent internal changes in xvid, but it produced messy output with 4 threads (with just 1 thread, everything worked fine).

So you have to wait until someone with more insights into the core than me fixes that, sorry :-/

I already get very close to full utilization of both processors when serving AviSynth into VirtualDub w/XviD. While explicit support for SMP in the codec would be cool, I'd like to point out that SMP users are already very happy indeed. :)
