I was trying out the Twitch function, I took the stream live, but nothing is being broadcasted (It's live, but the broadcast is pitch black).
I do understand that it is for testing purposes and it is full of bugs, but I am using the service correctly with precaution.
Please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report (
[minecraft|http://hopper.minecraft.net/help/finding-minecraft-data-folder]/crash-reports/crash-<DATE>-client.txt) here.
