增加rtmp協議配置
wujianjun@wujianjun-work?~/nginx-1.13.6?$?sudo?vi?/usr/local/nginx/conf/nginx.conf
在nginx.conf文件末尾增加以下rtmp協議的配置
rtmp?{ ?server?{ ??listen?1935; ??chunk_size?4096; ??application?live?{ ???live?on; ???record?off; ??} ?} }
啟動&測試
啟動nginx
wujianjun@wujianjun-work?~/nginx-1.13.6?$?sudo?/usr/local/nginx/sbin/nginx
啟動obs
打開剛安裝的obs軟件，在來源處配置圖像的推送來源（我這里選擇窗口捕獲），點擊右下角”設置”，進行如下圖配置流推送地址
配置完成后，點擊”開始推流”
啟動支持網絡流播放的視頻播放器(演示使用vlc播放器)
配置網絡流播放的地址，如下圖：
當點擊”播放”后，稍等幾秒，即可看到播放器顯示了obs捕獲的圖像了。
由于視頻流需要通過網絡進行傳輸，所以直播圖像會有幾秒的延遲。
http訪問直播視頻
1、更改nginx.conf中配置，增加hls配置(hls是在流媒體服務器中用來存放流媒體的文件夾),再次hls所在目錄設置為http協議訪問目錄即可，更改后的配置如下：
rtmp?{ ?server?{ ??listen?1935; ??chunk_size?4096; ??application?live?{ ???live?on; ???hls?on; ???hls_path?/usr/share/nginx/html/hls; ???hls_fragment?5s; ??} ?} } http?{ ?server?{ ?listen?80; ?..... ?location?/?{ ???#root?html; ???root?/usr/share/nginx/html; ???index?index.html?index.htm; ?} ?..... ?} }
注意：hls所在目錄nginx的用戶必須有寫入權限。
2、obs軟件配置錄制流名稱
在配置obs推送流url的下方有一個設置”流名稱”的地方，這里可以隨意填寫一個名稱（我這里示例填入”test”）
3、重啟一下nginx與obs軟件，我們即可在手機瀏覽器中輸入 http://ip/hls/test.m3u8 即可通過手機播放直播視頻。（直播延遲有點大，后續出文章優化）
