Pretty much everything confirms that you have a corrupt file. You might be
able to scrape some metadata out since it's partly playable, but IIRC most
of the interesting MP4 metadata is at the end (unless the file was
re-created for "fast start").
Is there specific metadata that you need?

Just based on that, it's possible (likely?) that the file wasn't properly
"finalized" when it was created, but I am not an expert here. You should be
able salvage the readable streams into another file by copying them with ffmpeg.
Also, please find out what "top-posting" is and avoid doing so on this
