For installting the ffmpeg on linux box I found following article very helpful

After installing the ffmpeg on your system you can use following commands for converting the video files to flv format.
avi to flv convert through ffmpeg
ffmpeg -i 00138.avi -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv final.flv
For creating the thumbnail the from video file you can use the folowing command.
create thubnail from movie file
ffmpeg -y -i moviefile.avi -vframes 1 -ss 00:01:60 -an -vcodec png -f rawvideo -s 110×90 new.png
In PHP you can use the following code easily.
$video_file = '/pathtovideo/test.avi';
$flvfile ='/pathtoflv/test.flv';
$png_path ='/pathtopng/test.png';
exec("ffmpeg -i ".$video_file." -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv ".$flvfile.");
//for thumbnail
exec("ffmpeg -y -i ".$video_file." -vframes 1 -ss 00:01:60 -an -vcodec png -f rawvideo -s 110x90 ".$png_path.");
Above code with convert the video file to flv format but my suggestion is convertion of video files will take so much bandwidth on server so use cronjob for converting the video files in night time.
