I suggest writing your own "FramedSource" subclass - using the code 
from the existing "ByteStreamFileSource" class as a model, to 
implement the "doGetNextFrame()" virtual function (assume that 
"READ_FROM_FILES_SYNCHRONOUSLY" is defined).  In your case - because 
you're reading from frames stored in memory - it should be very 
simple.  (Be sure to set "fPresentationTime" and 
"fDurationInMicroseconds" for each frame.)
