Here is my corrected question:

I have a YouTube MP4 video (test.mp4):

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mp4':
    major_brand     : mp42
    minor_version   : 0
    compatible_brands: isommp42
    creation_time   : 2015-10-28 06:13:56

      handler_name    : IsoMedia File Produced by Google, 5-11-2011

I have created an image file (testImage.png) from which I would like to make a 5 second MP4 file. Then
concatenate (prepend) this 5 second video to the test.mp4 file (as defined above). How can this be done in ffmpeg? Note, I am using:

ffmpeg version N-79947-gcd244fa Copyright (c) 2000-2016 the FFmpeg developers
built with gcc 5.3.0 (GCC)

Sorry for the previous poorly formulated email :-(
