[FFmpeg-user] Conversion to mp4 container

I am converting a video elementary mpeg4 stream to mp4 container format . I
used the following command

ffmpeg -i test043.avi -vcodec copy -an test043.avi.mp4

I am assuming that it will use the same codec for video as it is present in
the mpeg4 file. Is my assumption correct or first ffmpeg will decode it and
then re encode it again ?
