Jwplayer播放由php生成的m3u8

I use jwplayer to run m3u8 hls for a long time. I just want to create a dynamic m3u8 by php I can get the m3u8 file if I paste the php in browser directly. I also test the m3u8 file in VLC and no problem.

php:

<?php
/*
create m3u8 here
*/
header("Content-type: application/text");
header("Content-Disposition: attachment; filename=index.m3u8");
echo $m3u8file; 
?>

The m3u8 file output here:

#EXTM3U
#EXT-X-KEY:METHOD=NONE
#EXT-X-TARGETDURATION:10
#EXT-X-MEDIA-SEQUENCE:138497571

This script will show error in jwplayer "Error loading player: No playable sources found"

I fix it already. It seems that JWPlayer can only accept m3u8 but not php. I change the URL to http://xxx.xxx.xxx.xxx/tvod/tvod.m3u8?starttime=1384975713&endtime=1384975803. and rewrite m3u8 to php on server. And then it works.
