"MPEG4" is a bit ambigious, it refers to video codecs as well as a

You should really put encoded video into a container format, such as
matroska (matroskamux), MP4/ISO/Quicktime (mp4mux) or, if you absolutely
have to, AVI (avimux).
Also, if your matroska files contain MJPEG, you will need a decoder
between matroskademux and ffenc_mpeg4. Encoders can usually not encode
straight from JPEG format.
