[FFmpeg-user] Output image sequence duplicate first image

[Edward Park]

Hi,

> Use the output option -r or the fps filter to control the frequency of the image grabs. They will show different behaviour wrt the beginning of the grab cycle.

The identical frames at the start is surprising for me, why would that happen and not be counted as a duplicate? Does it happen when the frames aren't in the order that they're presented at the beginning?
