An alternative - which might be simpler for you - would be to write a 
new class (e.g. called "ContinuousByteStreamFileSource") that 
duplicates much of the functionality (and code) of the existing 
"ByteStreamFileSource" - except that it reads from its file 
continously - and just use this instead of "ByteStreamFileSource".

I.e, you would define your own subclass of 
"OnDemandServerMediaSubsession" that would be identical to the 
existing "MPEG2TransportFileServerMediaSubsession", except that it 
use a "ContinuousByteStreamFileSource" as input instead of a 
"ByteStreamFileSource".

As always, you should *not* need to modify any of the existing code.
