Just spot a bug. If there is Player Overlay Adv, there will be the following error for the embed link:
There will be no such an error and embed will word if there is no player overlay adv
I just noticed, that on some older embeed redtube videos is this warning: "Webmaster click here to update embed player" videos are not working, when u click link, then u are redirected to https://api.redtube.com/docs/.
is it possible, that old videos would work again?
