I’d like to know some opinions about an installation.
- 3 videoprojectors/screens (= 1 matrix only in jitter considering what I have to do)
- playing videos from files only, moving video matrices a bit and fading them
- playing multichannel sounds (no more than 4 x stereo) and no processing of sounds
videos are all DV formats (meaning that the global matrix won’t be more than 2160 x 576 pixels)
probably triplehead2go to use (?)
would a dedicated Mac Mini be enough ??
any helps or leads would be appreciated.
Hey, I’m using a triplehead like that as well, but for openGL rendering. 3 times 800×600 stitched together to 2400×600. For video I estimate a recent mac mini (core i processor) should be enough but make sure your videos are in a low CPU load codec like MJPEG.
thanks for your answer.
I target something like the i7 2,3Ghz + 8Go RAM
Ok about the codec stuff. That is important.
A big batch to push every content to MJPEG can easily be done by content providers.
i7 should be plenty.
Btw, instead of merging the 3 streams in 1 matrix you can upload ‘m to 3 videoplanes in one GL context. No heavy matrix operations needed. Use UYVY color mode for efficiency, see patches at http://abstrakt.vade.info/?p=147
Not sure how the integrated graphics processor of these mac mini’s handle this kind of GL operations though. You should compare the 2 approaches in practice.
targeting that proc because they have that budget and want to reuse the computer for other install. I think that could be good for their future.
thanks for the vade’s link. I have checked that one day. nice optimizations check list :)
