It might be possible, at least for the case of black bars due to an aspect-ratio mismatch. But it would take a lot of time to do, and I don't have enough time right now.
Hi there. Just love this script. I have got a silly question, would it be possible to have something added in this to remove the black bars on top and bottom of the video? I have seen/tried some codes which goes something like yt:crop=16:9 but I guess they only work in the tag section of the video creator? Even if some of the zooming extensions work, they all stop working after the video has been fullscreened.
Any solution to this? Thanks!
