[theora-dev] inter-frame vs intra-frame

[Jonathan Fabrizio]

Hi,
     The specification does not give any indication on when recording 
intra-frame. Obviously the first frame is an intra frame but after what 
is the strategy used in Theora ? I think an intra frame is recorded 
whenever consecutive frames become too different ? Is there any 
criterion ? What's happen in case of periodic changes (*blinking *lights 
for exemple) ?
     Thanks
J.F.
