FFmpeg - the requested output format "mpeg" is not an appropriate output format

I am trying to use FFmpeg to convert video from mp4 to mpeg format so that I can merge multiple videos. I have a custom build of FFmpeg where I manage the config options:

ffmpeg -y -i VID_20150514_171122_12085.mp4 -an -f mpeg VID_20150514_184208.mp4.0.mpg

But I keep getting the error: "The requested output format 'mpeg' is not suitable for the output format". This same command seems to work on my Ubuntu machine with a full FFmpeg build. What am I missing? I thought all mpeg encoders / decoders were included ... mpeg, mpegvideo, mpeg1video, mpeg2video.
