[FFmpeg-user] How to extract the very starting frame for every second on a live videi input?

[emb-pro]

HI Nicolas,

This is also one of my trials to get the output.

-vf
"select='if(not(floor(mod(t,1)))*lt(ld(1),1),st(1,1)+st(2,n)+st(3,t));if(eq(ld(1),1)*lt(n,ld(2)+1),1,if(trunc(t-ld(3)),st(1,0)))'"
-vsync 0

The above command is extracting the frames, but they are not in the sync.

Regards.
