I have troubles getting the color stream working in my Astra Pro. I downloaded the AstraSDK-0.5.0-20160426T102621Z-darwin-x64 to my Mac, then based on the ReadMe file to build the sample. Then the samples is compiled into samples/build/bin/ . There are SimpleDepthViewer, SimpleStreamViewer, SimpleColorViewer… Only SimpleDepthViewer works correctly, however, both SimpleStreamViewer and SimpleColorViewer show a black screen. Did anybody have this issue before? Can anybody help me for this problem? Thanks.
