Some videos play wrong way from some sites..is there a way to flip them

I have noticed some videos on various sites ie YouTube,Dailymotion etc play wrong way round...i know there are some software that can rotate 90 / 180 or make videos play them upside but i have not come across any thay play them right way round and you just see a mirror image of the original video ...is there a way to correct this.
with some software.

I think the term is 'flipping'

Fiddle around with settings in Video playback, in Display settings you can flip the screen and you can use a video editor like Clipchamp or photos legacy to flip downloaded videos.
