−Screenshort movie by mencoder.
+
−------------------------------
+
−::
+
−
+
−  $ mencoder "mf://*.jpg" -mf fps=30 -o output.avi
+
−
+
−Screenshort movie by ffmpeg.
+
−----------------------------
+
−::
+
−
+
−  mplayer -ao null -ss 0:0:33 -endpos 2 eagles.avi -vo jpeg:outdir=~/dir
+
−  mplayer -ao null -ss 0:0:33 -endpos 2 eagles.avi -vo png:z=9:outdir=~/dir
+
−
+
−Here:
+
−
+
− * ``-ss`` tells mplayer where you begin
+
− * ``-endpos`` tells mplayer where to stop (minutes)
+
− * ``z=9`` sets compression level
+
−
+
−ImageMagic and shell script.
+
−----------------------------
+
−::
+
−
+
−  #!/bin/bash
+
−  let iter=1
+
−  while [ "$iter" -le "$stop" ]; do
+
−    import $iter.png
+
−    sleep 1
+
−    let x+=1
+
−  done
+
−
+
−If you interesting in capturing specific window - by 'xwininfo' find,
+
−intereesting your window id (hex value) and use command::
+
−
+
−  import -window $windowid $iter.png
+
−
+
−To quick view result run::
+
−
+
−  $ cd $img_dir
+
−  $ animate -delay 20 *.png
+
−  ^C
+
−
+
−To compound image together::
+
−
+
−  $ convert -delay 20 *.png capture.mng  # license free, multi-image file format
+
−  $ convert -delay 20 *.png capture.gif
+
−
+
−You can add text to pictures before compound theirs::
+
−
+
−  $ mogrify -fill yellow -draw 'Rectangle 10,10 150,30' -fill black -pointsize 14 \
+
−     -draw 'text 15,25 "by http://example.com"' $iter.png
+
−
+
−If screen capturing slow for you use MIFF file format.
+
−
+
−Use root flag to capture all screen::
+
−
+
−  $ import -window root $iter.png
