Hello, i am using Wowza for WebRtc broadcasts with html5 hls. The problem is it is not working well on ios devices. (seems to work well everywere else)  
Stream strarts playing normally, but eventually freezes. It goes like:

1. load chunklist the first time
2. load all media segments
3. load chunklist the second time
4. stream sreezes

playlists looks ok to me:

```auto
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:13
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:12.472,
media_w1245802030_1.ts
#EXTINF:6.024,
media_w1245802030_2.ts
#EXTINF:11.642,
media_w1245802030_3.ts

```

```auto
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:13
#EXT-X-MEDIA-SEQUENCE:2
#EXTINF:6.024,
media_w1988418941_2.ts
#EXTINF:11.642,
media_w1988418941_3.ts
#EXTINF:9.264,
media_w1988418941_4.ts

```

packetizers is set:

```auto
<LiveStreamPacketizers>cupertinostreamingpacketizer, mpegdashstreamingpacketizer, sanjosestreamingpacketizer, smoothstreamingpacketizer</LiveStreamPacketizers>

```

cupertinoStreamingPacketizer pros is default

tested on IPad IOS9 IPhone5s IOS10

Spent some time on this one. Can you suggest something?

Thanks
