funily enough: ffmpeg -s 800x600 -r 25 -f x11grab -i :0.0 -vcodec huffyuv aout.avi works while: ffmpeg -vcodec huffyuv -f x11grab -s 800x600 -r 25 -i :0.0 aout.avi fails. This might or might not be a bug in ffmpeg's way of parsing options.
From the help I see: usage: ffmpeg [[infile options] -i infile]... {[outfile options] outfile}... infile options are supposed to be: -s 800x600 -r 25 -f x11grab then -i :0.0 then outfile options: -vcodec huffyuv then the outfile: aout.avi So this is, at least, documented :/

Nice. Thanks for this information.
