Introduction

Camera Engine is a re-usable component for embedded systems that leverages open-source techonologies like GStreamer and DBus to control media streaming, recording and video preview from remote user-interfaces (QT, webservices, etc).

The server uses GStreamer to perform RTSP streaming, record and preview videos simultaneously, as well as taking snapshots while it allows customization of certain parameters. Camera Engine exposes a D-Bus interface so multiple clients can perform actions over the server, regardless the programming language used. Camera Engine is designed to be portable, but is currently tested using DM368 and DM365 platforms.

Design

Currently, the server is designed with the following features:

• High definition 720p video capture
• Live video preview.
• Instant video recording encoded with h264.
• Streaming over RTSP encoded with h264.
• Instant snapshot taking, with JPEG image compression.

The following figure shows a general description of the pipeline used in Camera Engine.
