摘要
基于ARM11架构的微控制器S3C6410以及Linux操作系统成功实现数字视频传输。通过采用V4L2提供的接口函数,实现视频的采集;使用S3C6410自带的硬件编码模块实现视频编码;然后对H.264视频流进行RTP格式的打包;采用JRT-PLIB提供的库函数,对编码后的视频数据进行实时发送;最后使用VLC播放器解读SDP文件实现了实时播放,以验证传输系统的实际效果。
Reahime digital video transmission is successfully implemented based on ARMll-based microcontroller S3C6410 and embedded Linux operating system. It captures the video data by using V4L2, encodes the video by using the encoding module which is integrated in S3C6410, packets the H. 264 video stream according to RTP format, sends the encoded video data by using JRTPLIB in real time, and finally displays the SDP flies online in realtime by using VLC displayer.
