HDS video stalling at intervals

Hi, I’m pushing a RTMP stream into EMS. I’ve enabled autoHLS and autoHDS and I’m using Nginx to service http. HLS works fantastic. HDS plays, then stalls for 1-3 seconds and then sort of fast forwards up to speed. When playing I see the fragments being downloaded at regular interval, and suddenly it asks for the ‘bootstrap’ many times, the video stalls, and it get fragments again after a couple of seconds. I have tried tweaking playlistlength and chunksize, but the default values works best. What I see in Firebug is the following requests all with ‘200 OK’. GET xxSeg1-Frag12 GET bootstrap GET bootstrap GET xxSeg1-Frag13 GET bootstrap GET bootstrap GET xxSeg1-Frag14 GET bootstrap GET bootstrap GET bootstrap <—- Here the video stalls GET bootstrap GET bootstrap GET bootstrap GET bootstrap GET xxSeg1-Frag15 <— And here it continues/catches-up In the nginx access.log I see the same requests all served with status 200. As I understand the bootstrap file contains the list of the next ‘playlist length’ segments, which are 10+, so we does it download it all the time? I am looking forward to your help on this issue, as we really would like to get it working 🙂
