Image Stitching for NVIDIA Jetson/Examples/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 \
