I need to output a summary of a video as an animated gif. Ideally, I would have 8 equally-spaced frames from the video, and play them back one at a time, each for 0.25 seconds. So I'd have a 2 second animated gif.
This is what I have so far:
As you can see, I'm taking eight frames from the first eight seconds of video. What can I use to take eight frames from $timeOfVideo/7 time periods. Note that I'm dividing the time of the video by 7, not 8, so that I will have the first and last frames of the video in the gif.
My second problem is shortening the duration that each frame is shown. Currently, each frame is shown for 1 second. How can I reduce that to 0.25 seconds?
I am starting to think that ffmpeg is a better tool for the job, however, surprisingly I cannot find relevant examples in Google. Can ffmpeg do what I need? Can mplayer, for that matter? Something else?

Hello there!
Slightly off topic maybe, but maybe someone can help us. For a videoshow which will be called reality 6.1 we need a video file from a unix kernel that is compiling. Does anyone know how to capture this, or does anyone have such a vid?
cheers,

PLAYMPEG(1) General Commands Manual PLAYMPEG(1)NAME
plaympeg - MPEG audio (MP3) and video (MPEG-1) player
SYNOPSIS
plaympeg [options] file ...
DESCRIPTION
plaympeg is an MPEG audio and video player that uses the SDL MPEG Player Library. It can play back MPEG audio (layer 1, 2 and 3), MPEG
video (MPEG-1) and MPEG system (audio and video combined) files. MPEG-2 video files (as found on DVDs) are not supported.
The video player works best on a 16 bit color depth X11 display, it works on other color depths with reduced speed as well. You'll need a
CPU with 300 MHz or more to play back an MPEG system stream with 25 frames per seconds (fps) at full speed.
OPTIONS --help Show short usage information
--noaudio
Don't play the audio stream (if available)
--novideo
Don't play the video stream (if available)
--fullscreen
Play the MPEG video stream in fullscreen mode (this requires root privileges or a setuid plaympeg binary)
-2, --double
Play the MPEG video stream at double size
-l, --loop
Play the stream (audio or video) over and over again
-v N, --volume N
Set the volume of the audio stream to N% (N in the range of 0 to 100)
-s S, --scale S
