Then the app have to store all those messages in memory unless the pipeline is
active during the full session of analysis and we have to support seeking too
in this case. Because the user should be able to check the frames forth and
back. 
Suppose the user set the number of frames to be analyzed is equal to 1000, then
it needs to store a long list of structures in memory which in unnecessary (if
pipeline is not active whole the time). The situation will be even worse if the
user just try to analyze the whole number of frames in the media file(with out
specifying the number of frames to be analyzed).

Make the pipeline active and parse the stream again and again is another
option.
