I got a lot of examples here how to get Youtube image. But if video is non-standard format, for example, vertical, black frame appears on the image.
I found interesting link on this site where it can be cut by GET query: http://img.youtube.com/vi/XkOpbLBzPsY/hqdefault.jpg
.. I tried out with my image, but nothing happened, and not any info on what these parameters are for.
The question is: if we can do that as in above urls, how can I get these parameters info? If not, is there any other way to remove black frame?
Is it possible to get such clear image if we know Youtube code only?
