Descoberta de perfil (Perfil da câmera V2)

No esquema do Perfil da câmera 1507, a descoberta de perfil é centrada no dispositivo. Ou seja, o aplicativo deve determinar primeiro qual dispositivo o aplicativo deseja consultar e enumerar os perfis disponíveis para esse dispositivo.

As APIs de perfil de câmera existentes são suportadas para o perfil de câmera V2 e a API é estendida para fornecer informações adicionais de que o novo esquema suporta:
