Grip & Intermediate Vision Examples Errors

[SLAB-Mr.Thomas]

Our team wants to evaluate embedded C++ Grip code on the roboRIO. We can't find a complete C++ example on how to do it. Comments here on Chief Delphi point out some errors in the Grip generated C++ code and to use the check box when generating the code from Grip but no explanation of why to use the check box or not.

We thought the Intermediate Vision example available in Eclipse new WPILib example project might give some clues on what to do but that example fails to run correctly.

We can get the "raw" camera image from the roboRIO USB 0 camera to display on either of the Driver Station dashboards (default or C++) (essentially the Simple Vision example) but attempting the use the additional video stream for the "Rectangle" results in no output except the error message:

CS: ERROR: serve_Rectangle: Too many simultaneous client streams (MjpegServerImpl.cpp.403)

Selecting the Rectangle instead of the USB 0 camera device on the Dashboard does not change the error.

Any suggestions on how to get the embedded Grip C++ code to work and also the Intermediate Vision example?

Thanks.
