预备:
yum install -y automake autoconf libtool gcc gcc-c++
1.安装php
yum -y install php-gd php-xml php-mbstring php-ldap php-pear php-xmlrpc php-devel php-fpm
2.安装 nginx
yum –y install nginx nginx-devel
3.安装FFmpeg
安装 Install ffmpeg 等模块
yum -y install ffmpeg ffmpeg-devel
4.安装 php ffmpeg 扩展
tar jxvf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0
phpize
./configure
make
make install
切换到 php.d
生成 ffmpeg.ini文件 内容:extension=ffmpeg.so
5.安装yamdi
yadmi的作用是为flv文件添加关键帧，才能实现拖动播放
#下载yadmi
#安装yadmi
tar xzvf yamdi-1.4.tar.gz
cd yamdi-1.4
make && make install
使用方法：yamdi -i input.flv -o out.flv
6.配置nginx
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr – $remote_user [$time_local] ‘
‘"$request" $status $bytes_sent ‘
‘"$http_referer" "$http_user_agent" ‘
‘"$gzip_ratio"’;
keepalive_timeout 60;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
access_log off;
gzip on;
gzip_min_length 1100;
gzip_buffers 4 8k;
gzip_types text/plain;
output_buffers 1 32k;
postpone_output 1460;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
######################################################################
server {
listen 80;
server_name 192.168.1.145;
root /var/www/html/flv/;
limit_rate_after 5m; ####在flv视频文件下载了5M以后开始限速

location ~ \.flv {
flv;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
7.重启php-fpm nginx 测试
下载开源的JW Player,上传 测试 12.flv视频
8.生成时间截图:
ffmpeg -i 12.flv -y -f mjpeg -ss 3 -vframes 1 -t 0.2 -s 320×240 test.jpg
9.浏览器访问测试
type:协议类型
file:视频源文件
image:视频截图文件
