Using the program MediaInfo a video I looked at had the following
information-

gsst                                     : 0
gstd                                     : 598731
gssd                                     : BCDC235A3MH1922217440563422
gshh                                     :
o-o.preferred.iad07s12.v8.lscache8.c.youtube.com

Is there a way to delete this information using ffmpeg?
