Reading frames for the stream is completely different thing then
synchronization with time - stream reader doens't know anything about
real time flow.
If you want to use synchronized playback - you should take a look
at aviplay class which provides playback synchronized with realtime.
(though you currently can't select different speed)
Time synchronization is relatively complicated thing and will not
be a part of stream reading class (e.g. you might want to drop frame,
seeking, skiping without waiting and many other thing)
So yes - it's correct you should use something like aviplay class does
(eventually you may propose some updates to this class - i.e.
if you would like to see implemented support for some new command
(check the list))
