# Example pipeline to resize 2K RGB and depth stream to VGA resolution for display purpose remuxing the Object 
# Detection metadata as input for `zedodoverlay`

# 1) Define a `zeddatamux` object named `mux` to be used to recompose the RGB+metadata stream to be used to render 
#    the result of Object Detection using `zedoddisplaysink`. The `videoscale` filter indeed removes ZED metadata
#    from the RGB stream and the `zeddatamux` adds them back
# 2) Start `zedsrc` to acquire RGB and depth at 2K resolution stream enabling Skeleton Tracking (FAST).
# 3) Define `zeddemux` object named `demux` to demux the `zedsrc` composite stream creating three single streams: RGB, Depth and Data.
# 4) Rescale the Depth stream to VGA resolution and render it using `fpsdisplaysink`.
# 5) Set the data stream from `demux` as input on the data sink of `mux`.
# 6) Rescale the RGB stream to VGA resolution and set it as input on the video sink of `mux`.
# 7) Set the source of the muxer as input for `zedodoverlay` to draw Object Detection overlays
# 8) Convert the stream RGB stream with Object Detection overlay and display it using `fpsdisplaysink`.
