Question / Help Every time i start streaming LoL i have to restart my stream

[khentimentu]

So basicly my stream is working fine i guess, but every time when i'm loading into Leage of Legends game my game capture goes black but my monitor capture and webcam is working fine on stream. While im loading into game i have to restart my game and everything works perfectly then. It's kinda annoying but how can i fix it?
