We need to support a variety of applications on our 3D scientific 
visualisation client workstations, running SL6x x86-64 using the 
proprietary Nvidia 3D Xwindows drivers (and Nvidia CUDA5 along with OpenCL).

When I installed rpmfusion for vlc production current (2.0.6) for IA-32 
on my laptop, there were no issues.  When I attempt to install the same 
thing here, I find:

Test Transaction Errors:   file /usr/lib64/libBasicUsageEnvironment.so.0

I have found:

http://www.live555.com/liveMedia/

but nothing for live-2012 (nor my guess of live2012) that seems relevant 
to this issue.

I am not asking for specifics on debugging -- however, I do not 
recognize either live555 nor live-2012 except from the above search 
yields -- indicating that live555 provides a "set of C++ libraries for 
multimedia streaming, using open standard protocols (RTP/RTCP, RTSP, 
SIP)" -- that makes sense for an application such as vlc.  Does anyone 
know anything about these "packages"?  Will one suffice for the other 
and thus a manual install with a force nodeps override will in fact work?

Technical question:  for a .so file or an executable, ldd will inform as 
to the required dependencies.  What is the functional equivalent for a 
rpm file to ldd, preferably an equivalent that will list both the 
dependencies in terms of actual files (e.g., foobar.so.3.7.19-mnj) and 
(hopefully) the RPMs from a particular repository (e.g., SL, rpmfusion, 
etc., depending upon the distribution that supplied the RPM) that supply 
such files?

Otherwise, I am back to the issue of finding the "non-free" and other 
CODECs needed for vlc current production release built from source (not 
SRPM, but source).

Any information would be appreciated.
