How to utilize dual core CPUs with DivX 6? Which encoding software supports SMP? only, software, support, systems

andy

:
The DivX 6.1 codec now offers multi-threading support, giving you better performance on all HyperThreaded, dual core and dual CPU (SMP) systems. A new 1-pass encoding mode can cut encoding time in half by eliminating the need for multipass encoding in certain applications.

I just don't know how.  
In VirtualDub 1.6.14, I get quot;DivX 6.1.1 Codec (2 Logical CPUs)quot;, but when encoding, only approximately 50% CPU utilization is shown in the Task Manager, so obviously only one core is really used. And in the Codec configuration dialog, there are only the normal 1-pass and 2-pass options, nothing special (like the quot;new 1-pass encoding modequot;).

Sooo... what's wrong? Do I have to use a different encoding application to make use of both cores? If so, which?Thank you very much for your help! Best regards,

My motherboard(Asus P4P800) supports something about quot;2 Logical CPUsquot; but I am not sure. But I must insert 2 RAM module in pair.

Whatever this DivX 6.1.1 Codec (2 Logical CPUs) is encodes my DVD 40% to 50% slower than DivX 6.0. but the encoded by DivX 6.2 or 6.1.1 seemed better than 6.0, maybe it was just my illusion . So i am sticking with the newer version, but encoding was slower.

obvious Q so sorry if you did it - did you specify 2 threads?

The codec is only part of the performance equation. Your system must also decode and perhaps apply processing to the video, or management of the buffer. There is also I/O to consider.

Performance is going to depend upon your particular environment.

As far as the codec is concerned, it will launch a thread for each processor detected. The number of processors detected is shown in the codec name in the compressors enumeration.

Well, why is CPU utilization 50%? With x264 usage is 99 % for both cores.

cpu use is 99% on 2 diff pcs for me.

both X2's

Where? How?

It shows two detected CPUs, but it doesn't run two threads, because otherwise I wouldn't get 50% CPU load, but more.

And what about the quot;new 1-pass encoding modequot;? Can't find it anywhere.
