Running using GSTD
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 main difference in the pipeline syntax is that the homographies now need to be surrounded with escaped single quotes:
gstd # Launch gstd daemon, this will separate itself into its own process gstd-client pipeline_create stitcher_pipeline \ cudastitcher name=cuda \ left-center-homography=\'{\"h00\":2.47795806e-01, \"h01\":1.83125651e-01, \"h02\":1511, \"h10\":-9.58951851e-02, \"h11\":1.00466096e+00, \"h12\":3.43046193e+01, \"h20\":-1.84997102e-04, \"h21\":4.48703017e-05, \"h22\":1}\' \ right-center-homography=\'{\"h00\":1.07033034e+00, \"h01\":-8.91500609e-02, \"h02\":-1504, \"h10\":2.06014232e-02, \"h11\":1.06485384e+00, \"h12\":-2.68451772e+01, \"h20\":3.98503995e-06, \"h21\":4.20860985e-05, \"h22\":1}\' \ nvarguscamerasrc maxperf=true sensor-id=0 ! nvvidconv !
