@muldjord Weird, I thought I did put it under that thread.
Anyways, I couldn't help with c++ unfortunately.
However they do mention API's, but I'm not sure how to find them on their site. https://emumovies.com. Sorry, I'm not much help.

@Pupsenlalala I see UXS populated your <Video> tag... but with a wrong extension. (jpg)

Try to put "Default" in Configuration/Advanced/Image configuration Menu.
It will solve your problem.

(Need to put that on default config :S )
