Opencv

Hi guys,

I'm having a problem when i'm running a QC composition. I'm using the CVTools.plugin and placed it in the correct QC Patches folder. When is run my QC composition is giving me errors like described underneath. The plugin is working cause it's making use of some nodes within the plugin like OpenCVBGR2Gray patch. I'm surfing the web for a few hours now and I can't seem to fix it. Has anyone got an idea or a post for me with a solution. I'd tried running QC in 32-bit mode already an moving around the plugins.

these are my specs. MacBook MacBook5,2 Intel Core 2 Duo 2 GHz Mem: 2 GB Currently I'm running SL 10.6.2

these are the errors

Re: Opencv

Have you actually got Structure Tools installed? You'll be needing it if you haven't :-)

I know this sort of message might be consequent upon the failure of the CV Tools plugin, although I could say the same of any composition that relies upon the CV Tools or another plugin for that matter that is provoking problems [version number / framework changes, etc ].

Thing is, it's non-reproducible as a problem for me using the example compositions made available by Kineme, in fact they are working very well indeed.

It may be that the problem is partly caused by your having a composition that utilises a prior OpenCV before OpenCV from Kineme at least, became CVTools.

The file attached does work for me in QC 64 bit & 32 bit on 10.6.x .

Hope that clarifies and helps.

[ BTW - you're not the henry jalink with escaption.nl by some chance ? - pardon the potential homonymic / namesake confusion aforehand ] .

Re: Opencv

Hi henry,

I'm having the same problem, everything is placed in the correct directory...

Have you manage to solve it?
