Error de la cámara 2 android 6.0

Por favor ayude a entender lo que significa: E / Camera: Error 2. Mi cámara-código no funciona en android 6.0 solamente y el otro funciona. Este código es para escanear un código qr. En la vista previa 6.0 no está incluido, pero puede incluir flash.
Los permisos de tiempo de ejecución están activos. A veces: W / System.err: java.lang.RuntimeException: getParameters falló (parámetros vacíos) en onPreviewFrame.
