 The same system is used for the other image formats.
+ at section Only GIF is listed by -format. Is that the only accepted image format?
+No, there are more; they are listed among the video codecs:
+  jpeg, png, ppm, pbm, pam, pgm.
+For example:
+ at example
+  ffmpeg -f image2 -i menu.png -f image2 menu.jpg
+ at end example
+The @file{menu.png} used as input will be converted to @file{menu.jpg}.
+Instead of relying on file format self-recognition, you may also use
+ at table @option
+ at item -vcodec ppm
+ at item -vcodec png
+ at item -vcodec mjpeg
+ at end table
+to force the encoding.
+Applying that to the previous example:
+ at example
+  ffmpeg -f image2 -vcodec png -i menu.png -f image2 -vcodec mjpeg menu.jpg
+ at end example
+Beware that there is no "jpeg" codec. Use "mjpeg" instead.
 @section FFmpeg does not support codec XXX. Can you include a Windows DLL loader to support it ?
 No. FFmpeg only supports open source codecs. Windows DLLs are not
