Can anyone running a linux and win32 box try to run this example and see if it completely drains you of CPU. I have tried it with 3 macs and I can't seem to do much more in PD. Also does anyone know of a less cpu intensive way to track objects in PD using a mac like pix_multiblob does. I would like to track at least 20 objects. My project is dead unless I figure out a better way. Thanks, Alain

I made a 400x300 motion JPEG-a movie 15 fps with 5 solid blue circles moving on a black

background

to test pix_mutiblob. I open it up with pix_film, flip it with pix_flip and send it to pix_multiblob. I

suddenly

notices PD getting very, very slow. When I look at the cpu usage in activity monitor (if you can

believe

activity monitor) I get 100-104% cpu usage. I cant do anything else in PD because PD gets so slow.

I

am using a dual 2Ghz G5 with ATI Radeon 9800 XT and 3GB of internal memory. Is this normal?

What

can I do to lower cpu usage? What else can I use within Gem to get the same results? I eventually

want

to be able to track 20-30 objects but It looks like it would be imposible at this rate. Thanks, Alain
