The two Sade file have the MP4 atoms which describe where the AAC frame
are located at the end of the file (i.e. after the mdat atom)  and
streaming playing native such as suqeezelite and Touch need the MP4 atom
at the start of the mp4 file (i.e. before the mdat atom) .  LMS streams
a file to a player starting at the beginning whereas PC based player
such as VLC - analyse the whole file before playing it.

ffmpeg can be used to convert a "problem" mp4 by moving the mp4 atoms
from the end to the start.  This is known as the "faststart" option

Code:
--------------------
    
  ffmpeg -i in.mp4 -c copy -map 0 -movflags +faststart out.mp4
  
--------------------


If the file is trasncoded by LMS  using faad then I think faad processes
the whole file before before streaming it as PCM>
