+Animated GIF muxer.
+It accepts the following options:
+ at table @option
+ at item loop
+Set the number of times to loop the output. Use @code{-1} for no loop, @code{0}
+for looping indefinitely (default).
+ at item final_delay
+Force the delay (expressed in centiseconds) after the last frame. Each frame
+ends with a delay until the next frame. The default is @code{-1}, which is a
+special value to tell the muxer to re-use the previous delay. In case of a
+loop, you might want to customize this value to mark a pause for instance.
+ at end table
+For example, to encode a gif looping 10 times, with a 5 seconds delay between
+the loops:
+ at example
+ffmpeg -i INPUT -loop 10 -final_delay 500 out.gif
+ at end example
+Note 1: if you wish to extract the frames in separate GIF files, you need to
+force the @ref{image2} muxer:
+ at example
+ffmpeg -i INPUT -c:v gif -f image2 "out%d.gif"
+ at end example
+Note 2: the GIF format has a very small time base: the delay between two frames
+can not be smaller than one centi second.
