Running dynamic pipeline of compositor gets segmentation fault

[David Ing]

Perhaps I am mistaken but I dont think  you can concatenate a string
literal with an integer using the + operator.  Other methods are shown
here:

Also I wonder if it is necessary to pause the pipeline before you start
removing pads and linking new ones.
