ffmpeg can definitely do a 180 degrees rotation of a video (or a combination of vertical and horizontal flips, which give the same end result).
See for example https://superuser.com/questions/578321/ ... ith-ffmpeg.

If the component you are referring to is libav, is has the hflip and vflip filters to do just that.
See https://libav.org/documentation/libavfilter.html#hflip

But just to make sure, I downloaded ffplay (you can't get more ffmpeg-ish than that) and used it to play my sample MP4. It played the right side up.

Screen output from ffplay:
