Where are those OSC messages implemented (and documented)? How do they work? Are they only part of the CasparCG client? So far, I haven't found anything about them in the server source code and I seldom use the client.Select the output you have added above from the Output drop-down box. In the Path field enter /event/status. In the Message field you can enter one of the following: reset, start or stop. Select String from the Type drop-down box.
