Sometimes on Facebook when I add the ?rel=0
to the end of a YouTube link to disable the related videos from showing at end of video, it automatically change that ?rel=0
to %3Frel%3D0
once I click Done Editing? Why does it do this sometimes and not others? What does %3Frel%3D0
do differently than ?rel=0
does? Or do those two do the same thing?
Also, can you add both &fmt=18
and ?rel=0
to the end of a YouTube link on Facebook?
