[FFmpeg-user] Extract a frame

[nonya bidness]

Thanks for that, I did try the timestamps and it does indeed work.  The
reason I was trying the previous method is that with the timestamp, I was
unable to get FFMpeg to stitch together a time lapse of the images trying
to use 2019-%14d or similar.  Do you have any suggestions on how to go
about doing that?
