hls

HLS playback

HLS live and VOD

Main HLS URL that allows to play a live stream or a VOD file. This URL responds with master playlist.

Exact version of HLS is not defined here, it may vary according to different settings.

Authorizations:

tokenAuth

path Parameters

name

required

string

Examples:

clock - Stream name example
vod/movies/bunny.mp4 - VOD file name example

The name of a stream or a VOD file. It may be multi-segment, i.e. /part1/part2/part3.

For a VOD file, it consists of the VOD storage name and a path to the file within the storage.

query Parameters

separate_audio

boolean

Example: separate_audio=true

Whether audio tracks are specified separately in the playlist.

This option is used for some players like Samsung TV or browsers supporting MSE that cannot switch between multiple audio tracks (for instance, for different languages) and, as a result, do not display such audio tracks. For such cases, Flussonic can create a playlist with separate audio.

thumbnails

integer

Example: thumbnails=100

This parameter is applicaple for a VOD file only (for a live stream, it is ignored).

If it is specified, the thumbnail playlist is added to the primary playlist. Example of the thumbnail playlist:

#EXT-X-IMAGE-STREAM-INF:BANDWIDTH=10000,RESOLUTION=320x180,CODECS="jpeg",URI="images-320x180/tpl-0-34-100.m3u8"

This value defines how many thumbnail links will be added to the thumbnail playlist to cover the file duration. The player will add the thumbnail links to the progress bar at regular intervals. The duration of the interval between thumbnails is the whole duration of the file divided by this value.

NOTE: This option requires the parameters thumbnails enabled=ondemand and size included in the VOD location settings. For example, thumbnails enabled=ondemand size=320x240;.

HLS rewind

Nice combination of live and DVR HLS playlists.

This request gives something like HLS live playlist, but with lot of segments.

If the player understands that there are too many segments for a plain live playlist, it allows to rewind back into DVR window.

We recommend to take a look at Clappr player that supports this feature out of the box.

path Parameters

name required	string Example: clock Stream name. It may be multi-segment, i.e. `/part1/part2/part3`.
ago required	integer Example: 7200 DVR window size in seconds. It is a duration of an HLS manifest in seconds, so your clients will be able to pause the stream up to this period or rewind it, for example, to the start of a TV show.

query Parameters

separate_audio

boolean

Example: separate_audio=true

Whether audio tracks are specified separately in the playlist.

This option is used for some players like Samsung TV or browsers supporting MSE that cannot switch between multiple audio tracks (for instance, for different languages) and, as a result, do not display such audio tracks. For such cases, Flussonic can create a playlist with separate audio.

HLS DVR

If your stream is already recorded on the server with DVR, you can use this URL to play a specified DVR window, for example, you can play a telecast if you know its beginning and end from EPG.

This URL works in two modes: file and event. If depth is specified as now, this url will respond with a growing playlist for playing an event.

If depth is an exact positive number, then the server will respond with playlist, having this requested amount of seconds of video as a file.

Note the following rules:

The first segment in this playlist will not start earlier than from.
The last segment in this playlist will not start later than from + depth.

For example, two playlists: archive-1600000000-3600.m3u8 and archive-1600003600-3600.m3u8 will give the same result as archive-1600000000-7200.m3u8.

This URL is a recommended way to play DVR, because it allows pausing. If a player can seamlessly switch between different URLs, you can make seamless DVR playback with non-overlapping HLS DVR requests.

path Parameters

name required	string Example: clock Stream name. It may be multi-segment, i.e. `/part1/part2/part3`.
from required	integer Example: 1641045644 The start time of the DVR window in UTC seconds.
required	integer or string The duration of the DVR window in seconds. You also can specify `now` for a DVR window till current time.

query Parameters

separate_audio

boolean

Example: separate_audio=true

Whether audio tracks are specified separately in the playlist.

This option is used for some players like Samsung TV or browsers supporting MSE that cannot switch between multiple audio tracks (for instance, for different languages) and, as a result, do not display such audio tracks. For such cases, Flussonic can create a playlist with separate audio.

thumbnails

integer

Example: thumbnails=100

If this parameter is specified, the thumbnail playlist is added to the primary playlist.

Example of the thumbnail playlist:

#EXT-X-IMAGE-STREAM-INF:BANDWIDTH=10000,RESOLUTION=320x240,CODECS="jpeg",URI="images-320x240/tpl-1644304617-60-100.m3u8"

This value defines how many thumbnail links will be added to the thumbnail playlist to cover the requested duration of the DVR window. The player will add the thumbnail links to the progress bar at regular intervals. The duration of the interval between thumbnails is the whole duration of the DVR window divided by this value.

NOTE: This option requires the parameters thumbnails enabled=ondemand and size included in the stream settings. For example, thumbnails enabled=ondemand size=320x240;.

HLS absolute timeshift

If your stream is already recorded on the server with DVR, you can use this URL to play the recorded stream by HLS starting at a specified moment of time. For example, you can use it for old STBs or viewing recoreded shows with EPG.

Please note that when you use the same timeshift URL several times, any additional requests use the same existing session. Therefore the time is not pure "absolute" and is still related to the current session. Therefore every time you request the same time, you get different part of the video. To solve this problem, you can change the token parameter in every new request to start a new session. For example:

http://FLUSSONIC-IP:80/CHANNEL-NAME/timeshift_abs-1430227800.m3u8?token=123 - the first request,
http://FLUSSONIC-IP:80/CHANNEL-NAME/timeshift_abs-1430227800.m3u8?token=124 - the second request, and so on.

from required	integer Example: 1641045644 The start time of the DVR window in UTC seconds.
required	integer or string The duration of the DVR window in seconds. You also can specify `now` for a growing playlist till current time. If `from`+`depth` is in the future, the playlist will grow as well until it reaches the specified moment.

query Parameters

period

string

Value: "mono"

Flussonic can create DASH manifest of two types: with multiple periods and with a single period.

By default, Flussonic creates a multi-period manifest. If there is a gap in playing a stream (for example, when the stream is restarted) or video quality changes, Flussonic starts a new period of playing, so there are multiple continuous periods in the resulting playlist.

However, such a manifest is incompatible with a wide range of devices and TV sets. In such cases you can specify period=mono option, i.e. http://FLUSSONIC-IP/STREAMNAME/archive-TIME-DURATION.mpd?period=mono. As a result, Flussonic will recalculate timestamps of all frames and join the parts of the interrupted video together into a single period.

Please note that this option should not work in the event mode because Flussonic cannot join a period in future.

thumbnails

integer

Example: thumbnails=100

If this parameter is specified, the thumbnail playlist is added to the primary playlist.

Example of the thumbnail playlist:

 <AdaptationSet id="3" mimeType="image/jpeg" contentType="image">
         <SegmentTemplate media="$RepresentationID$/dvr-1648098000-$Time$.m4v.jpg" duration="771"></SegmentTemplate>
         <Representation bandwidth="10000" id="images-320x240" width="320" height="240">
            <EssentialProperty schemeIdUri="http://dashif.org/guidelines/thumbnail_tile" value="1x1"/>
         </Representation>
  </AdaptationSet>

This value defines how many thumbnail links will be added to the thumbnail playlist to cover the requested duration of the DVR window. The player will add the thumbnail links to the progress bar at regular intervals. The duration of the interval between thumbnails is the whole duration of the DVR window divided by this value.

NOTE: This option requires the parameters thumbnails enabled=ondemand and size included in the stream settings. For example, thumbnails enabled=ondemand size=320x240;.
