Video surveillance in simplex wireless channel based on GStreamer

摘要

GStreamer is a pipeline-based multimedia framework written in the C programming language with the type system based on Gobject. Aiming at transmitting streaming media in simplex wireless channel with stochastic time slot, our paper propose a new framework based on Gstreamer to achieve real-time video collection in multi-resolution and adjustable frame rate. The video is then encoded in X264 which is fast with adjustable coding parameter to adapt to the special channel.The encoded video was encapsulated with RTP and pushed to the channel as UDP datagram.The received data flow has to be decapsulated in jitter buffer and decoded with Ffmpeg on the receiver.With the requirement of storage, we propose to add new elements to storage and play the video.Experiments demonstrate that our new framework can realize real-time video transmission. Also our framework makes sure that surveillance video is smooth and clear with acceptable delay.
