Thanks a lot, @mdotedot
Tested on Android, and it works.
It would be ideal to have blocks to set the size and position of the video player window, as well as the possibility of playing a video file stored in the "extras" folder to get an immediate video playback.
Also, it would be useful to have a block to check if the video playback has finished.
I would like to add to my games some short video intros as this feature gives a very professional look to commercial games.
