You may know certain settings when the file was created but you don't know
things like the specifics of the streams in the container (such as "where
does it start in the file?"); the moov atom is effectively the Table of
Contents for an MP4 container.
Oh, and you have plenty of evidence of file damage- it's in the error
messages you posted; if it wasn't damaged, it should easily play with all
the tools mentioned.
Search for "moov atom not found"- you'll find a lot of discussion on the
matter. One _possible_ solution is something called "untrunc", which I have
not tried. If the moov atom just isn't there, I don't think ffmpeg will help
