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.
 | This example only works for JP4.x! |
Running with bash GSTD client
The execution with GSTD is the same as any other pipeline.
gstd # Launch gstd daemon, this will separate itself into its own process gstd-client pipeline_create stitcher_pipeline \ cudastitcher name=stitcher \ homography-list="`cat homographies.json | tr -d "\n" | tr -d " "`" \ nvarguscamerasrc sensor-id=0 ! nvvidconv ! "video/x-raw(memory:NVMM), width=1920, height=1080" ! queue ! stitcher.sink_0 \ nvarguscamerasrc sensor-id=1 ! nvvidconv ! "video/x-raw(memory:NVMM), width=1920, height=1080" ! queue ! stitcher.sink_1 \ nvarguscamerasrc sensor-id=2 ! nvvidconv ! "video/x-raw(memory:NVMM), width=1920, height=1080" ! queue ! stitcher.sink_2 \ stitcher. ! queue ! nvvidconv ! "video/x-raw(memory:NVMM), width=1920, height=360" ! nvoverlaysink gstd-client pipeline_play stitcher_pipeline
For x86 follow:
