[GEM-dev] .mov linux optimisation

[cyrille henry]

hello,

i noticed that reading a 640x480 30fps .mov file with gem use 70% of my 
cpu. (2.13 centrino)

the same file read with vlc use less than 10%

is there anything i can do optimise movie in gem?

here is my ./configure output.

thanks
Cyrille
