Hardware question : Mac Mini, opengl and HD

September 13, 2006 | 4:59 pm

Hi jit.list,

What sort of experience have people had with the Intel Minis? I’ve
used them for simple kiosk type applications and they work very well
for that, and for simple video playback and networking operations, but
I’m curious if anyone has tried doing HD playback on a macmini
(ideally using opengl) while also doing some simple compositing? And
background subtraction?

How much can they be asked to handle? Are the new Intels up to the
task? Is the integrated video card enough, or not so much?

Inquiring minds want to know!

(thank you)

In my experience testing Jitter on the Intel Mini, they perform quite
well as long as you are not doing anything too texture-memory intensive.
This means you will be limited in the number of jit.gl.slab or
jit.gl.texture objects you can reasonably use, and some shaders (i.e.
td.rota.jxs) may be too complex for the graphics card.

YMMV,
Andrew B.

Thanks Andrew. If that’s the case, I think they will do well, as the
project is a ways off (+6 months). I would expect any sort of
hardware change in that time would help rather than hinder and also
allow plenty of time to optimize the patch :)

Just a quick followup for the archives, I tested a 720p pjpeg encoded
video with 2 640 * 480 images composited on top at at the apple store
on a macbook. While not the ideal test platform, it gave me a good
idea of what to expect on mini hardware (integrated graphics,
comporable speed & memory) and was able to get about 25fps.

so yeah, it works :)
