Crashes with detectobject

vvvv beta bug
1

I have found a bug with DetectObject from the addonpack.

I’ve tried both 45beta34.1_x86 and 45beta34.2_x86 under Windows 8.

The issue is if you change texture source (eg a new filetexture) for DetectObject sooner or later I will get a ‘vvvv has stopped working’ crash. For me it’s after only 3 - 5 texture changes.

Test patch with test files attached.

Same for me. vvvv_45beta34.2_x86 crashes with a Runtime Error when I try DetectObject(Freeframe) and with the DetectObject(Imagepack). The haarcascades are not within the Imagepack, so I use these files for both trackers: opencv/data/haarcascades at master · opencv/opencv · GitHub

I use win10

@tobyk i was able to work around your problem by having the size of the textures not change. ie. on the FileTexture (EX9.Texture) i set a fix value for Width and Height via inspektor.
