[YouTube-API] youtube url modifiers

Hello

I am programming with the youtube api and I was looking at some of the headers that were being sent,
for example the s.youtube headers

https://s.youtube.com/s?nsidf=2&md=1&len=349.115&csipt=watch5&nsiabblmean=155423.623&el=detailpage&docid=suwLPxSNY1o&nsiabblc=69&vid=eCiOBX5XBsoFE9Fx2fQ1mBZNDQGSG2gjC&hasstoryboard=1&sd=B4A7D6725HH1335401463045355&volume=100&tspfdt=1436&hcbd=1188672&h=360&hcbt=0.8069999999999999&bd=5587956&nsivbblmax=65885.000&tabsb=1&bt=9.108&w=480&nsivbblmin=14532.000&plid=AAS-imGcelOnmjqN&cfps=30&screenw=1366&screenh=768&playerw=640&hl=en_US&fmt=34&playerh=390&scoville=1&mos=0&vtmp=1&fexp=904542,906030&referrer=None&fs=0&nsivbblmean=51999.377&rt=11.890&vq=auto&nsivbblc=69&sendtmp=1&vw=480&ns=yt&vh=360&et=10.054&rendering=software&st=0&decoding=accelerated&nsiabblmax=161296.000&hbd=2617406&tsphab=1&hbt=1.152&tspne=0&lact=14994&nsiabblmin=54503.000&bc=5822435&cr=US

I was wondering if there was a manual or a guide for what each of the url modifiers meant; if someone can shed some light for this i would be in your debt

thank you
