Comment:

 Look at the hls m3u8 content:

 {{{
 StevenLiu:dash StevenLiu$ curl http://fftest.kda.io/prod.m3u8
 #EXTM3U
 #EXT-X-VERSION:3
 #EXT-X-ALLOW-CACHE:YES
 #EXT-X-MEDIA-SEQUENCE:7022
 #EXT-X-TARGETDURATION:11

 }}}


 It have no EXT-X-ENDLIST,so it should be a live streaming m3u8,

 you can try the -m3u8_hold_counters options by the master git head,
 this option will terminate ffmpeg by refresh m3u8 without new segments.
