I am typing those via my phone, and cannot test any code soon.

İf you are using pipe processes with ffmpeg executable, the 
terminal output can be a mix of outputs of ffmpeg and your main 
process. This makes difficult to search for errors. I think since 
your main process is interrupted due to an error (maybe an opencl 
error), ffmpeg stops too. Please note that the centroid tracking 
example does not use ffmpeg-d (you can modify the code to use it 
though).

For Mac you should use bindbc-glfw by deleting the subconf:

	"subConfigurations": {
		"dcv:plot": "use-glfw-d"

You can also try using equivalent DCV functions instead of opencl 
to eliminate opencl errors.
