 .m4a files support album art
 .mp4 files support cover art

 currently you can add the art in this way

 {{{
 atomicparsley infile.mp4 --artwork infile.png --overWrite
 }}}

 However once muxed with FFmpeg some changes happen

 {{{
 ffmpeg -i infile.mp4 -c copy -map 0 outfile.mp4
 }}}

 1. The png stream changes from

 {{{
 png
 }}}

  to

 {{{
 png (m[0][0][0] / 0x006D)
 }}}

 2. Thumbnail disappears, example
    http://superuser.com/a/524120

 3. If you open in VLC instead of just playing video it also opens a second
 window with the png
