流媒體服務(wù)器是一種專(zhuān)門(mén)用于傳輸實(shí)時(shí)數(shù)據(jù)流的服務(wù)器軟件,廣泛用于視頻直播、視頻會(huì)議、音頻播放等應(yīng)用場(chǎng)景。在嵌入式開(kāi)發(fā)領(lǐng)域,將流媒體服務(wù)器部署到開(kāi)發(fā)板上可以實(shí)現(xiàn)諸如視頻監(jiān)控、實(shí)時(shí)數(shù)據(jù)傳輸等功能。本文將介紹如何利用nginx和其rtmp流媒體模塊,在ELF 1開(kāi)發(fā)板上搭建一個(gè)高效穩(wěn)定的流媒體服務(wù)器。
1、下載源碼

root@ELF1:~# ./nginx -V
root@ELF1:~# ./nginx -h
(2)啟動(dòng)nginx
root@ELF1:~# ./nginx -p /etc/nginx/
