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,

FAKENECT-RECORD(1) libfreenect manual FAKENECT-RECORD(1)NAME
fakenect-record - program to save dumps from kinect to file
SYNOPSIS
fakenect-record [-h] [-ffmpeg] [-ffmpeg-opts options] outputdir
DESCRIPTION
fakenect-record dumps the output of the kinect in outputdir folder. It saves the acceleration, depth, and rgb data as individual files with
names in the form "TYPE-CURRENTIME-TIMESTAMP" where:
* TYPE is either (a)ccel, (d)epth, or (r)gb
* TIMESTAMP corresponds to the timestamp associated with the observation (or in the case of accel, the last timestamp seen)
* CURRENTTIME corresponds to a floating point version of the time in seconds.
The purpose of storing the current time is so that delays can be recreated exactly as they occurred. For RGB and DEPTH the dump is just
the entirety of the data provided in PPM and PGM formats respectively (just a 1 line header above the raw dump). For ACCEL, the dump is
the "freenect_raw_tilt_state". Only the front part of the file name is used, with the rest left undefined (extension, extra info, etc).
A file called INDEX.txt is also output with all of the filenames local to that directory to simplify the format (e.g., no need to read the
directory structure).
Once started, the program will continue to acquire data from the kinect. When you want to stop it, hit Ctrl-C and the signal will be
caught, runloop stopped, and everything will be stored cleanly.
OPTIONS -ffmpeg
If present, send the the video stream to ffmpeg
-ffmpeg-opts options
When using ffmpeg, specify the options to be used with it. If unspecified, it will use the options "-aspect 4:3 -r 20 -vcodec
msmpeg4 -b 30000k"
-h Display the command-line help
