Black screen appears before start in DialogFragment

Hi, thanks for the library. It's really cool. But I have some troubles with your library in DialogFragment.
I have black screen before video start. It is appear for a second, after that video start.
What is it? In Activity all alright, but I have to use DialogFragment.

A workaround for this issue would be to animate alpha of the player from 0 to 1 in 1~2sec so that the black screen is skipped during the transition.
