TCP-based connections in a studio environment always have the potential to tear down your whole equipment because a program fails if the server-client connection got lost. P.S.: the main advantage of OSC is that it is UDP-based and not TCP-based as websocket. Thanks for reading and I hope this was of interest. to try this in OBS-Python directly with OBS and not via websocket. I have to mention that this is a very easy task to write in python on a raspberry pi but it was a pain in the a. But in my studio environment I need real buttons and not only a touch screen or a mouse and therefore I am using Novation Lauchpads with interfaceprograms (written in processing) which do the logic of litting and darkening the buttons and do a transformation of the midisequences to osc-commands(which are sent to the CasparCG Client). OSC can be used in essentially two ways with QLab: as a relatively simple remote control protocol, in the spirit of MIDI, or as a robust two-way protocol for. I know that this is far, far away from streaming. SWITCH to INPUT2 as PROGINPUT of ATEMMIXERĪnd this all by sending /control/181, 1 as OSC-Message to the Client where I have defined UID 181 as REMOTE TRIGGER. Platform(s): There are non-Mac workarounds provided by the company. It can send OSC cues coordinated with sound and lighting cues, allowing for flexibility of control of a variety of devices on and off stage. SWITCH to CAM3 as SOURCE of UPSTREAMKEYER 3 QLab is a popular show control software popular among theater technologists. The Client also works without a CasparCG Server to control Blackmagic Atemmixers, Tricasters, PTZ-Cams from Sony and Panasonic.īy defining groups in the CasparCG client I can do things like this in my rundown: (You can define an endless number of servers in the CasparCG Client). I am sending the OSC-Messages to the interfaceprogramm out of the CasparCG Client because this standalone Programm is both - an OSC Server and an OSC Client. Wsc.sendMessage( "") īecause the quotes (") are essential they are escaped with a backslash so that they are really written into the string. The program now looks into it´s own table and finds there as member 1-1 = 0 the name of the first scene and sends an request to the websocket server which looks like this: Therefore I am able to write to the osc-server-port of this interface programm an osc message ´/scene/1.n' and it does not matter what type of data you send. This programm always has a correct table with the scenenames and their actual numbers. I have solved this for myself by writing a small programm in process which acts as a client to the websocket server of the OBS and parses all the JSON-Messages from the server. The address of the reply starts with /reply/ and ends with the address of the invoked method.Hello you few that are also interested in OSC-SupportHello! The reply is sent to the IP address from which the original message was received. Exceptions are noted below, such as cases where a reply may be larger than the maximum size of a UDP datagram. The OSC API behaves almost identically when using both UDP and TCP. For example, sending the text /cue/selected/start to QLab on UDP port 53535 will have the same result as sending the actual OSC command /cue/selected/start to port 53000. QLab also listens for plain text on UDP port 53535, and attempts to interpret it as OSC. When talking to QLab via TCP, messages are framed using the double END SLIP protocol ( RFC 1055) as required by the OSC 1.1 specification. Replies to OSC via UDP are sent on port 53001. When talking to QLab via UDP, each OSC message corresponds to one UDP datagram. QLab listens for incoming OSC on port 53000. The QLab OSC API can be used over both UDP and TCP transport layers. What follows here is a complete dictionary of QLab’s OSC implementation. QLab has an extensive API (application program interface) for OSC which allows you to control QLab from any device or software which can broadcast OSC messages.
