I am developer of Reactor Player plugin http://www.mediachance.com/reactorplayer/index.html
and it seems as if Affinity photo sends empty alpha channel to the plugin if nothing is selected. The plugin works fine everywhere else in Photoshop, Corel etc as it should - when nothing is selected then the plugin receives only 3 channels..., but in Affinity Photo if no selection is made, I am still receiving empty alpha channel (that is fully transparent).
If selection is made then I receive the correct 4 channels with opaque pixels. I will patch this on my side, but I am curious why it is this way?
