1 # Live HLS Research
2 This document is a collection of notes on Live HLS implementations in the wild.
3
4 There are two varieties of Live HLS. In the first, playlists are
5 persistent and strictly appended to. In the alternative form, the
6 maximum number of segments in a playlist is relatively stable and an
7 old segment is removed every time a new segment becomes available.
8
9 On iOS devices, both stream types report a duration of `Infinity`. The
10 `currentTime` is equal to the amount of the stream that has been
11 played back on the device.

16 "Sliding window" live streams.
17
18 ### Variant Playlists
19 Once variant playlists look like standard HLS variant playlists.
20
21 ### Media Playlists
22 OnceLIVE uses "sliding window" manifests for live playback. The media
23 playlists do not have an `EXT-X-ENDLIST` and don't declare a
24 `EXT-X-PLAYLIST-TYPE`. On first request, the stream media playlist
25 returned four segment URLs with a starting media sequence of one,
26 preceded by a `EXT-X-DISCONTINUITY` tag. As playback progressed, that
27 number grew to 13 segment URLs, at which point it stabilized. That
28 would equate to a steady-state 65 second window at 5 seconds per
29 segment.
30
31 OnceLive documentation is [available on the Unicorn Media
32 website](http://www.unicornmedia.com/documents/2013/02/oncelive_implementationguide.pdf).
33
34 Here's a script to quickly parse out segment URLs:
35
36 ```shell
37 curl $ONCE_MEDIA_PLAYLIST | grep '^http'
38 ```
39
40 An example media playlist might look something like this:
41 ```m3u8
42 #EXTM3U
43 #EXT-X-TARGETDURATION:5
44 #EXT-X-MEDIA-SEQUENCE:3
45 #EXTINF:5,3
