Most efficient means of making player transparent
I haven't seen a comprehensive discussion of making the player transparent. I seem to understand two possible methods.
I have seen discussions in which hiding all features and controls on the player (next, back, seekbar, audio, notes, resources, glossary, etc) results in the thin border of an apparently transparent player.
I have also seen discussions in which it is advised to make elements on the playbar 100% transparent in the advanced color editing section of the player properties.
So, I'm confused, if I hide all the features, tabs and controls on the player, do I need to make anything transparent? If I go the transparent route, still intending a completely transparent player, what elements must be made transparent? The base elements, presumably, but what else?
