 # Key Features
 GStreamer plugin package for ZED Cameras. The package is composed of several plugins:
 
-* `zedsrc`: acquires camera color image and depth map and pushes them in a GStreamer pipeline.
-* `zedmeta`: GStreamer library to define and handle the ZED metadata (Positional Tracking data, Sensors data, Detected Object data, Detected Skeletons data).
-* `zeddemux`: receives a composite `zedsrc` stream (`color left + color right` data or `color left + depth map` + metadata),
+* [`zedsrc`](./gst-zed-src): acquires camera color image and depth map and pushes them in a GStreamer pipeline.
+* [`zedmeta`](./gst-zed-meta): GStreamer library to define and handle the ZED metadata (Positional Tracking data, Sensors data, Detected Object data, Detected Skeletons data).
+* [`zeddemux`](./gst-zed-demux): receives a composite `zedsrc` stream (`color left + color right` data or `color left + depth map` + metadata),
   processes the eventual depth data and pushes them in two separated new streams named `src_left` and `src_aux`. A third source pad is created for metadata to be externally processed.
-* `zeddatamux`: receive a video stream compatible with ZED caps and a ZED Data Stream generated by the `zeddemux` and adds metadata to the video stream. This is useful if metadata are removed by a filter that does not automatically propagate metadata
-* `zeddatacsvsink`: example sink plugin that receives ZED metadata, extracts the Positional Tracking and the Sensors Data and save them in a CSV file.
-* `zedodoverlay`: example transform filter plugin that receives ZED combined stream with metadata, extracts Object Detection information and draws the overlays on the oncoming filter

+## RTSP Server
+
+*Available only for Linux*
+
+An application to start an RTSP server from a text pipeline (using the same sintax of the CLI command [`gst-launch-1.0`](https://gstreamer.freedesktop.org/documentation/tools/gst-launch.html)) is provided.
+
+Usage:
+
+```
+   gst-zed-rtsp-launch [OPTION?] PIPELINE-DESCRIPTION
+```
+
+Help Options:
+*  `-h`, `--help` -> Show help options.
+*  `--help-all` -> Show all help options.
+*  `--help-gst` -> Show GStreamer Options.
+
+Application Options:
+*  `-p`, `--port=PORT` -> Port to listen on (default: 8554).
+*  `-a`, `--address=HOST` -> Host address (default: 127.0.0.1).
+
+Example: 
+
+```
+   gst-zed-rtsp-server zedsrc ! videoconvert ! 'video/x-raw, format=(string)I420' ! x264enc ! rtph264pay pt=96 name=pay0
+```
+
+It is mandatory to define at least one payload named `pay0`; it is possible to define multiple payloads using an increasing index (i.e. `pay1`, `pay2`, ...).

 Ready to use scripts are available in the scripts/ folder for windows and linux.
