[Transfer] Use jwplayer Nginx to build a video on demand server to solve the problem of slow drag loading_html/css_WEB-ITnose

flvVideos can be published in two ways:
1. Ordinary HTTP download method
2. Based on Flash Media Server or Red5 server's rtmp/rtmpt streaming method.

Most well-known video websites use the former method.
A comparison of the two methods is as follows:
Http: After generating the keyframe, it can be dragged and played, and server resources will no longer be consumed after the download is completed.
Rtmp/rtmpt: Drag and play at will, no caching, each playback will consume server resources



Here I will talk about how to use nginx to build an http-based video on demand server, which is mainly divided into three steps:
1. nginxInstallation and configuration
1. Download the latest win32 version of nginx and unzip it to any directory
2. Open cmd and enter the nginx directory, use Command start nginx to start nginx (the default configuration is confnginx.conf, the -c option can be used to specify the configuration file to be used, and more parameters can be viewed using nginx ?h)
2. nginxSupport for flv
1. Edit the configuration file confnginx.conf and add the following configuration:
Add the configuration to start gzip in the http block
gzip on;
gzip_min_length 1100 ;
gzip_buffers 4 8k;
gzip_types text/plain;
Add configuration to enable flv in the server block:
limit_rate_after 1m; #Start speed limit after downloading 1M
limit_rate 100k; #Will The speed limit is 100k/s
location ~ .flv {
flv;
}
2. Use the command nginx ?s reload to reload the configuration file
3. Client player
1. Download the open source flash player jwplayer
2. Extract the file to the html directory under nginx
3. Visit http://localhot/player.swf ?type=http&file=1.flv can play the video

Note: Now the video can be played, but the drag function is not supported because "keyframes" are not added to the flv file. The tools that can be used are " yamdi" and "flvtool", taking the yamdi win32 version as an example, download and unzip it and enter cmd to execute:
yamdi ?i src.flv ?o dst.flv
means to add keyframes to src.flv and output for dst.flv.
OK, now we can visit http://localhot/player.swf?type=http&file=dst.flv and drag and play freely.
