Fantastic, thanks a lot for that quick and very precise answer. I've managed to update the code quickly, however, I'm just facing a little issue : I am not completely sure what the "reuseFirstSource" parameter in the OnDemandServerMediaSubsession() constructor means.
I set it to True as explained in the documentation. I initially thought I could instantiate one single H265VideoStreamDiscreteFramer object (and one single "customized" class for its FramedSource input source), however I quickly got an execution violation as both the framer and the input source objects are destroyed in OnDemandServerMediaSubsession::sdpLines() by the "Medium::close(dummyRTPSink);" line. So, I guess I'll have to instanciate both the framer, and my custom input source to that, each time createNewStreamSource() gets called. Or do I have to only instanciate a new frame, but use the same single input source object ?

Should I write a custom class, that > inherits from “OnDemandServerMediaSubsession” ? Yes. However, this requires reimplementing just two virtual functions in this subclass: “createNewStreamSource()” and “createNewRTPSink()”. “createNewStreamSource()” should be simple: Just create an instance of your source object, and pass it to “H265VideoStreamDiscreteFramer::createNew()”. And the code for “createNewRTPSink()” will probably be exactly the same as that in “H265VideoFileServerMediaSubsession.cpp”.
