I have two mp4 files (the first (testImage.mp4 with no audio) created
from a png file with ffmpeg [vers. N-79947-gcd244fa Copyright (c) 2000-2016
the FFmpeg developers built with gcc 5.3.0 (GCC)]
and the second (test.mp4 width video and audio) downloaded from YouTube.
I obtained the following information on these files using
ffprobe [vers. N-79947-gcd244fa Copyright (c) 2007-2016 the
FFmpeg developers built with gcc 5.3.0 (GCC)]:
