In the Descriptors from OpenCV I have the following line: descriptor2 = DescriptorExtractor.create(DescriptorExtractor.BRIEF);

But there is Also a DescriptorExtractor.OPPONENT_BRIEF

What is the exact difference between the two? I tried to google Opponent_brief for OpenCV, but got no good answer anywhere.

The opponent color space is used, see http://docs.opencv.org/modules/features2d/doc/common_interfaces_of_descriptor_extractors.html?highlight=opponent#opponentcolordescriptorextractor . Note: You need a 3-chan input-image and the output-descriptor-size will be three times the normal size.
