Hello,
Souhaitant migrer mes caméras de MotionEye sous Frigate, je bute sur la configuration de 2 caméras USB branchés sur le pi accueillant HA supervised; je connais leur adresse /dev/video0 (une vieille Logitech Quickcam Ultra Vision) et /dev/video2 (une vieille Gopro Hero3) et elles sont visibles sous VLC ; j’ai beau faire preuve de tout le chamanisme (dixit @golfvert 
), de nombreux essais et de recherches web (y compris éplucher https://docs.frigate.video/) mais je n’arrive toujours pas à les faire fonctionner; quelqu’un aurait-il une idée de la manière de les configurer ? 
Voici les éléments que j’ai :
