 If you want to create a video out of just one image, this will do (output video duration is set to 30 seconds):
 {{{
-ffmpeg -loop 1 -f image2 -i img.png -vcodec libx264 -t 30 out.mp4
+ffmpeg -loop 1 -f image2 -i img.png -c:v libx264 -t 30 out.mp4

+If you don't have images numbered and ordered in series (img001.jpg, img002.jpg, img003.jpg) but rather random bunch of images, ffmpeg also supports bash-style globbing - though glod wildcards (such as `?`, representing a single random character, and `*` representing any number of random characters) have to be prefixed with a `%`:
 {{{
-cat *.jpg | ffmpeg -f image2pipe -r 1 -vcodec mjpeg -i - -vcodec libx264 out.mp4
+ffmpeg -f image2 -r 1 -i %*.jpg -c:v libx264 out.mp4
 }}}

 {{{
-cat *.png | ffmpeg -f image2pipe -r 1 -vcodec png -i - -vcodec libx264 out.mp4
+ffmpeg -f image2 -r 1 -i %*.png -c:v libx264 out.mp4
