You would need to write one or more filters that:
1/ extracts data from the MPEG-2 Transport Stream
2/ parses this data into PES packets
3/ collects together the data from the PES packets that form a Video 
Elementary Stream
4/ parses this data to get the "picture_coding_type" from the picture 
header, and count those that are I-frames.

Needless to say, you would need to be familiar with the MPEG speci.
