Ich wollte hier fragen ob jemand eine Idee hat warum mein Programm meine Webcam nicht erkennt.
Ich versuch mich bisschen mit tracking zyu beschäftigen.
System Ubuntu 16
Kamara würde mit chees gestestet und funktioniert
Programm funktioniert mit video.
Das ist die ausgabe die ich durch getBuildInformation() bekomme
