= Generating a rick-roll file =
Generating an avi or mov movie from a single picture file is done with the following script:

{{{#! /bin/bash

for i in `seq 2 $1`;
do
        cp 1.jpg $i.jpg
done
mencoder "mf://*.jpg" -mf fps=1 -o test.avi -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=800
ffmpeg -i test.avi test.mov
for i in `seq 2 $1`;
do
        rm $i.jpg
done
}}}
The picture you want to be in the movie has to be called 1.jpg for this script to work.

Converting the given movie test.avi to a flv is done with the following command

{{{
ffmpeg -i test.avi -vcodec libx264  -vpre libx264-superfast -f flv test.flv
}}}

To do the whole thing in a single step
{{{
for i in `seq 2 $1`;
do
        ln 1.jpg $i.jpg
done
ffmpeg -i %d.jpg -r 25 -vcodec libx264  -vpre libx264-superfast -f flv -y timinutter.flv
for i in `seq 2 $1`;
do
        rm $i.jpg
done
}}}
