ffmpeg would give you ffmpeg's idea of which frames were which. There is,
however, no hard rule about which frames are any particular type. Any b frame
can be replaced by an i frame or a b frame, and any p frame can be replaced by
an i frame. b frames take the least storage but the most time to decode, so
the storage vs time tradeoff has to be made in light of what storage transfer
bandwidth and what processing power is known to be available.
