Breeze v.5.5.x works with Windows 2000 / XP / Vista.
The minimum hardware requirements to the computer are the following:
- CPU: Pentium III or higher
- RAM: 128 Mbytes or more
Current version of Breeze has been tested on x86 platforms with up to:
- CPU: total, 4 processors or/and cores, running at the frequencies up to 3.8 GHz
- RAM: 16 gigabytes.
It is IMPORTANT to remember that CPU and RAM resources required for processing
video or graphics depend on structure and complexity of processed video data.
Usually most important are size of picture frame, level of video compression,
frame rate of video sequences and number of simultaneously processed video
streams.
For example, size of QCIF picture is 176 x 144 = 25344 pixels. Size of HDTV
1080p video picture is 1920 x 1080 = 2073600 pixels, or about 80 time bigger
than size of QCIF picture. Often it means that processing HDTV 1080p picture
will require about 80 times more computations than processing of QCIF picture.
Breeze has been tested for processing of pictures with the size up to 6000 x
3000 pixels, or about 10 times bigger than HDTV 1080p (about 1000 times bigger
than QCIF).
Usually encoding and /or decoding of highly compressed video or graphics
requires a big CPU power. Fast reversible replaying of video sequences (instant
playback) is done usually via storing a big number of frames in RAM. It may
require a big quantity of RAM, up to 2 gigabytes and more.
Breeze essentially is a multiple stream processor. On the computers equipped
with multiple processors (with single or multiple cores), Breeze may process
data in multiple threads, utilizing all CPU resources.
As a result, in the case of most demanding tasks, if it is required by the
complexity of job, Breeze may utilize all CPU and RAM resources available at
the computer.
Multiple processor / core computer configurations are highly recommended when
Breeze is used for playing two or more video sequences simultaneously. This is
especially important for playing a high definition video, and when big
magnification of video images (up to 10x), "Picture In Picture" or "Picture
From Picture" are used.
