I apologize should I abuse the forum. I haven't seen any forums for C++ depthai discussions.
Here is my problem:
Using an OAK-D I'm trying to get a depth and a color video stream. Just adding the color stream to the stereo_example.cpp causes a run time error:
`terminate called after throwing an instance of 'std::runtime_error'
what(): Communication exception - possible device error/misconfiguration. Original message 'Couldn't read data from stream: 'left' (X_LINK_ERROR)'

I'm on depth-ai v2.0.0 and this are the changes in stereo_example.cpp

    to false.
    Currently extended stereo modes are not supported with color camera.

    Thanks, that helped. Any pointers where I can lookup dependencies like that and hints on how to synchronize the depth/disparity and the color stream.
