Hi Louis,

	First of all, let's be honest GDCM does not handle out of the bog 
encapsulated MPEG. I tried it as a proof of concept, that's all. In fact 
the work to be done to handle those is quite difficult. The only MPEg 
library that is BSD-compatible -that I found- is a C lib which work with 
FILE* (duh!), the real problem is that GDCM manipulate istream. So there 
will be a transition to do right here already. I think -I don't 
remember- but the MPEG lib expect the mpeg stream to start at offset 0, 
which is not the case for DICOM-MPEG file.
	All boils down to how much time you have to develop, and how much C/C++ 
skill you have.

	As a side note, GDCM and CMake are cross plateform tool, so the 
compilation on GNU/Linux should be very similar to the step for 
compilation on Win32.
