How to save a screen region to gif.
Raw
save-screen-to-gif.sh
# Need to install ffcast, and advisedly also xrectsel (on arch can do from AUR)
# Below command will let you select a region with the mouse, than stream it to ffmpeg.
# Many args magic (taken from SO), but allegedly it saves as lossless.
ffcast -s % ffmpeg -f x11grab -show_region 1 -framerate 20 -video_size %s -i %D+%c -codec:v huffyuv -vf crop="iw-mod(iw\\,2):ih-mod(ih\\,2)" out.avi
# Use ImageMagick to covert to gif - works great!
convert -set delay 5 -layers Optimize out.avi out.gif
