nginx 播放视频(1)

1,首先拷贝一个flv文件到nginx 的html目录中

cp /var/www/html/ajl/uploadvideos/20150428101917_31520150408监利新闻（三）.flv ./

flv文件的路径是:/usr/local/nginx/html/broadcast2/20150428101917_31520150408监利新闻（三）.flv

 

2,把flv视频格式转化为ts

ffmpeg -i 20150428101917_31520150408监利新闻（三）.flv -acodec copy -vcodec libx264 20150428101917_31520150408监利新闻（三）.ts

3,切片

segmenter -i 20150428101917_31520150408监利新闻（三）.ts -d 10 -p segmenter_test -m vp5.m3u8 -u http://123.57.250.51:8080/broadcast2/

-d 10：每个切片为10秒，

-p segmenter_test：切片的名字的前缀

 

     -u URL地址：m3u8中播放列表的地址前缀

Output #0, mpegts, to 'segmenter_test':

4,打开vp5.m3u8 确认里面的切片路径是否正确

一定要确保切片(ts文件)的url是有效的
