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

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
5,命令列表
cd broadcast2/
cp /var/www/html/ajl/uploadvideos/20150428101917_31520150408监利新闻(三).flv ./
