When starting an RTSP stream to watch my Surveillance camera live stream, it instantly causes a sadface.
This worked before the update, I know this as it is a function that I uses almost every day.
Just to be sure, i made a complete reinstall of OSMC to just to be sure that nothing else could cause this.
Full debug logs are Here
The logs are a paste of the original logs, where I have removed the credentials for the RTSP stream, as the log uploader failed to do that automatically.
EDIT: The stream plays fine in VLC
