mencoder - skip frames


hi guys,

i would like to copy some frames from a video.
I am trying this command to copy the whole video:

Code:
mencoder  -of avi -nosound -ovc copy When_Galaxies_collide__Latest_images_from_NASA_and_Hubble.flv  -o  out.flv
1. how can i do to copy some frames after skipping another ones?

2. how can i do to get just one frame; i mean on image (jpg) ?

thanks in advance,

Hector

Assuming that you know the starting and trailing cut points, first cut off the tail, then cut off the start section. If you would start by cutting the head, then you would need to recalculate the end position when dealing with the tail.

Just a sample:
Quote:
mencoder -endpos "00:20:33" -ovc copy -oac copy \
"in.avi" -o "out.avi"
mencoder -ss "00:11:15" -ovc copy -oac copy \
"out.avi" -o "final.avi"
Arch Linux
