[x264-devel] FrameSkip option

[Samer Chikhani]

Dear all,
I'm trying to encode a sequence of 10seconds at 2 different frame rate 
say 30fps and 5fps. Using the option -fps in the x264 will lead to 2 
sequences of same size. What i need is to make the x264 coder drop some 
frames so it can meet the target frame rate and still be of duration 10s.
I know that using the reference software there is the option FrameSkip 
that does what i need. But what is the equivalent (if any) for the 
FrameSkip in the x264 codec? somehow i'm not able to find any...

Anyone has an idea about that?
