The v4l2RTSPserver is an open source project from 'mpromonet' which we make use of in the RPOS project.
So you are probably better off asking the question on the mpromonet github pages.

But, looking at the error, I wonder if you have a different version of live555 that the v4lrtspserver does not compile against
