Well, I have my fast RTP Analysis architecture ready.
That means that pointers to all RTP frames are stored in a global list in
order to analyse only the frames of the selected RTP stream.
This list is calculated when the RTP Streams or -Analysis dialog boxes get
opened for the first time. The calculation needs a complete redissection of
all frames.
Now the question is:
1 - should the list be recalculated each time we open the dialog box?
(Annoying for frequent uses, but allows to release the memory when the
dialog box is closed)
or
2 - keep it in memory and recalculate it only when its content changes?
(This needs we have to tell somehow *when* the content has changed)
