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 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
