Run by selecting region on screen with mouse :) (it's the same as using the -s parameter):

$ my_ffcast

Select window (remove -f if you don't want borders)

$ my_ffcast -f -w

more options with man ffcast

Requires: https://github.com/lolilolicon/FFcast

and uses subcmd lag

This pointed me to the palettegen/paletteuse filters, so thank you!

I wrote a simplified version of convert_to_gif: v2gif
I also put together a wiki page "GIF Howto". Feel free to improve it :)

@lolilolicon you're very welcome!!

your bash skills are awesome!! going to update my scripts :)

ps. just saw you comment now and the wiki page seems simple and awesome, I'd love to improve but can't see on what :p
