1,首先拷貝一個flv檔案到nginx 的html目錄中
cp /var/www/html/ajl/uploadvideos/20150428101917_31520150408監利新聞（三）.flv ./
flv檔案的路徑是:/usr/local/nginx/html/broadcast2/20150428101917_31520150408監利新聞（三）.flv
2,把flv視訊格式轉化為ts
ffmpeg -i 20150428101917_31520150408監利新聞（三）.flv -acodec copy -vcodec libx26420150428101917_31520150408監利新聞（三）.ts

segmenter -i 20150428101917_31520150408監利新聞（三）.ts -d 10 -p segmenter_test -m vp5.m3u8 -u http://123.57.250.51:8080/broadcast2/
-d 10：每個切片為10秒，
-p segmenter_test：切片的名字的字首
-u url位址：m3u8中播放清單的位址字首

4,打開vp5.m3u8 确認裡面的切片路徑是否正确
一定要確定切片(ts檔案)的url是有效的
