Why are you polishing anything on mobile/html5 when the sound isn’t even working for Windows? I realize you guys are pushing into that space, but your primary focus is still windows is it not?
This is frustrating to have an advertised feature that is broken for three major builds. I don’t care about format issues, I can always convert for now to work around it.
Some other issues I have noticed:
Videos continue playing outside of play mode in the editor if they were started while in play mode. This had the amazing effect of causing UE4 to lock when pressing play again if I let it run too long.
I often lose control of the media player while in editor, so that even while playing, hitting a pause function in a blueprint or in the media player file itself will no longer stop it.
