In other words: your decoder is able to convert GOPs with the
initial F frames and the included Pand B frames to I frames
sequences only?  Hey, I'd like to know if there is a
open source library around which can do this in software.
libmpeg2 is not an option AFAIK there is no decoding required
to do this.
