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.
Note
This example only works for JP4.x
Running with bash GSTD client
The execution with GSTD is basically 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:
gstd # Launch gstd daemon, this will separate itself into its own process gstd-client pipeline_create stitcher_pipeline \ cudastitcher name=stitcher \ homography-list="`cat homographie.json | tr -d "\n" | tr -d "\t" | tr -d " "`" \ videotestsrc pattern=ball ! videoconvert ! "video/x-raw, width=1920, height=1080" ! queue ! stitcher.sink_0 \ videotestsrc pattern=smpte ! videoconvert ! "video/x-raw, width=1920, height=1080" ! queue ! stitcher.sink_1 \ videotestsrc pattern=snow ! videoconvert !
