FFmpeg 实现视频分片及播放

转码分片、截取封面

ffmpeg -i video.mp4 -c:v libx264 -hls_time 120 -hls_list_size 0 -c:a aac -strict -2 -f hls /play/video.m3u8 

ffmpeg -i video.mp4 -y -f mjpeg -ss 3 -t 1 -s 900x500 /play/video.jpg 

nginx设置

在server节点下添加

location /play {
	alias  /play/;
}
# location /play {
#    root /;
#    # 跨域
#    add_header Access-Control-Allow-Origin *;
#    types{
#        application/vnd.apple.mpegurl m3u8;
#        video/mp2t ts;
#    }
#    add_header Cache-Control no-cache;
#}

Centos7 搭建 RTMP 流媒体服务

下载nginx-rtmp-module模块

wget https://github.com/arut/nginx-rtmp-module/archive/master.zip
unzip -o master.zip

安装nginx

yum install -y gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel
wget http://nginx.org/download/nginx-1.19.6.tar.gz
tar -zxvf nginx-1.19.6.tar.gz -C /usr/local/
cd /usr/local/nginx-1.19.6
# 配置nginx增加上面下载的模块
./configure --prefix=/usr/local/nginx --add-module=/root/nginx-rtmp-module
# 编译、安装
make
make install 

修改nginx配置
