Error with two tracking webcam

Hi,

I get an error if i try to use two webcams tracking . The two webcams start and opencv capture well . But the filters aren't activated . I need help please !!

Thx for your help, i sent a noWorky . There's a lot of Gson errors but all work well exect the tracking .

I think the important error is this one :
