Publishing URL format
The following table describes the entrypoint hostnames and pathnames for Media Services Live 4.0 and above.
Encoders should be capable of using a POST URL in the following format.
|Media Services Live 3.2||Media Services Live 4.0 and above|
|New hostname: |
|Current URL path:
|New URL path: |
The following 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/*
For details about the unique session ID, see Unique session ID
|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.
There are no changes on the delivery side. The playback URL format remains the same, which is: http://example-i.akamaized.net/cmaf/live/[stream_id]/[event_name]/[filename_.m3u8_or_.mpd]
