[Live-devel] Proper use of StreamReplicator

No, I meant “getNextFrame()” - i.e., the regular call that an object makes to get data from an upstream “FramedSource”.  You need to provide your own ‘after getting’ and ‘on close’ functions and data.  There are numerous examples of this in the code.

No, it works just fine.  It just needs to be used properly.

In any case, I’ve pretty much used up all the free help I can give you on your project right now.
