[GEM-dev] pbs with GEM on macpro quad

[cyrille henry]

hello,
i'm curently working on a mac pro quad (and HCS pd39-2-extended RC1).
i've got 2 problems.

1 st : reading movie does create a new thread as i can see in activity 
monitor, but the cpu used by pd + reading movie does never exeed 100% 
(i.e 25% of the all CPUs).
is there a solution to improve this? i would like to be able to play 
many movie using 4 core of this computer.


i also have a problem with pix_coloralpha. it look like pix_coloralpha 
does not change the alpha chanel of the movie.
i test the same patch / same movie on linux where everything is working 
ok. is there something that i should know to use this on osX?

thanks
Cyrille
