freecad를 재시작하거나 처음 시작하면 workbench에 FreeCAD MCP 라는게 생겨난다.
메뉴에서 FreeCAD MCP - Show FreeCAD MCP Panel 누르면 Tasks에 창이 열리는데 Start Server 눌러준다.
freecad 에서 start RPC server 하면 9876 포트로 생성된다.

Signals GObject signals can be used to notify applications of events specific to this object. Note, however, that the application needs to be aware of signals and their meaning, so if you're looking for a generic way for application-element interaction, signals are probably not what you're looking for. In many cases, however, signals can be very useful. See the GObject documentation for all internals about signals.
"capsfilter caps=" 생략하고 쓰면 알아서 capsfilter로 인식하는 건가?
Example launch line gst-launch-1.0 videotestsrc ! capsfiltercaps=video/x-raw,format=GRAY8 ! videoconvert ! autovideosink
Limits acceptable video from videotestsrc to be grayscale. Equivalent to gst-launch-1.0 videotestsrc ! video/x-raw,format=GRAY8 ! videoconvert ! autovideosink
