I’m facing a problem with scaling the player to the layout, when it initializes it appears in small dimensions, i think those for the buttons layout of the player, means a very small view and the user of course can’t watch a video inside that, and even if i use the scale block it doesn’t change anything, but when i enter full screen mode and then cancel it, the player’s dimensions become perfect just like i want! 
So i think you’ve got two problems; automatic scaling at initialization and manual scaling with the block both of them don’t work 
I hope you can fix this as soon as you can, i think it isn’t hard for an amazing developer like you!
