GStreamer_Daemon is a gst-launch on steroids where you can create a GStreamer pipeline, play, pause, change speed, skip around, and even change element parameter settings all while the pipeline is active.
Running with bash GSTD client
The execution with GSTD is basically the same as any other pipeline. Just be extra careful with the quotes and spaces when specifying the camera matrix and distortion parameters. The correct format when using Gstd is shown belown.
gstd # Launch gstd daemon, this will separate itself into its own process
