Web Based UI #1191

Hi, Is it possible to run Carla in a headless Raspberry Pi and control it from a Web GUI using some kind of protocol?

Web -> http -> Backend -> Carla

Or does it exposes any public API so I can implement an http backend?

falkTX commented 4 years ago

You can use carla-control over the network (it uses OSC protocol). There is no HTTP version, I tried to start one with c++ "restbed" but it keeps crashing and building it in debug mode seems problematic, so I stopped trying.

@falkTX it sounds like a proxy can be created:

Web -> HttpProxy -> OSC -> Carla

Can you point me to some OSC protocol documentation?

falkTX commented 4 years ago

The Carla OSC protocol is not documented, and it ties to the Carla version at the moment. best I can do is point you to the code https://github.com/falkTX/Carla/blob/develop/source/frontend/carla_control.py#L314 (there is a TCP and UDP connection at the same time btw)

The WIP, crashy REST stuff is at https://github.com/falkTX/Carla/tree/develop/source/rest
