Publishing URL format
Encoders should be capable of using a POST URL in the described format.
- URL Path:
This table describes the publishing parameters.
|URL Path Element||Description|
|stream_id||Unique identifier for the stream provided by Akamai.|
|uniquesourcename||This is a nomenclature change of the current event name. This is the first URL path component following the stream_id. Use this name to identify the current media source from a set of sources ingesting into Akamai.|
|Unique sessionID||This is needed to distinguish different
encoder restart points and make sure that path duplications do not overwrite the media
objects across the restart points. |
For example: for a 24x7 source, a good recommendation is to have a string with the date time string at the time of connection. <stream_id>/<uniquesourcename>/20160628T18h22m10s/* or <stream_id>/<uniquesourcename>/T1467082295/*
|bitrateID||A unique path element to distinguish media segments specific to a bitrate. It is mandatory to have this path element. Bitrate in kilo bits of the corresponding media object should be extractable using a regular expression such as:
|OPTIONAL_PATH||Other fixed pathnames for specific work
flows that are not mandatory. For software releases prior to Media Services Live 4.0,
this is the directory rollover pathname. |
Media Services Live 4.0 and above does not require directory rollover. You can upload all of the segment objects for a specific bitrate into the same URL path.
However, to ensure compatibility the encoder should continue to support both directory rollover as well as non-rollover options in the short term.
The playback URL format remains the same as previous MSL versions, which is: https://example-i.akamaized.net/cmaf/live/[stream_id]/[event_name]/[filename_.m3u8_or_.mpd]
