摘要
由于近年来人们对网络实时视频需求的不断增长,文中提出一种基于Gstreamer框架且运行在Panda Board ES硬件平台的安全视频流传输系统。该系统集合了V4L2视频采集框架、H.264压缩编码技术等多种技术,其中端到端的流传输运用到了RTP流媒体传输协议。文中将对视频流传输系统的搭建进行全面的描述,最后经Gstreamer管道测试进行验证其可行性,同时由于本系统设计中加入了AES加密算法,其保证了系统的安全可靠。测试结果表明,该系统能实时、安全、准确地传输视频流,满足了人们日益增长的实时视频需求。
Due to the growing demand for real-time video in recent years,this paper proposes a secure video stream transmission system based on Gstreamer framework and it runs on Panda Board ES hardware platform.The system set up a V4L2 video capture framework,H.264 compression coding technology and other technologies,in which the RTP streaming media transmission protocol application to the end to end streamingtransmission.This paper will conduct a comprehensive description on building the video stream transmission system,finally through the Gstreamer pipeline test to verify its feasibility,at the same time as the system designing with AES encryption algorithm,which ensures the safety and reliability of the system. The test results show that the system can transmit the video stream in real time,safely and accurately,and it can meet the needs of the people in real time.
