thanks,

sorry for bothering with these dumb questions, but i`m in the middle of 
the project with psp,
and the only solution seems to be ffplay,

how i can find out which are keyframes and how to decode them,
shell i call decode_thread ?

i would be very grateful for some step by step guide,
since i`m a bit newbie,

i hope is not to much to ask for...

best,
wojciech
