[FFmpeg-user] file corruption: youtube, youtube-dl, or what?

[Albretch Mueller]

 As I have been noticing youtube-dl downloads were corrupted way more
often than I would think if attributed to random download corruption
~
 Other users had noticed it as well

 How could ffmpeg (probably probably in tandem with scanning/binary
comparison utilities) be used to check how (the metadata and/or the
payload) of those media files differ?
