| Name | Type | Default Value | Notes | Minimum Version Supported |
| title | String | N/A | Title of the publishing point | 3.0 |
| estimatedTime | Uint32 | 0 | Estimated duration of the live event in seconds. | 3.0 |
| lookaheadChunks | Uint32 | 2 | Number of look-ahead chunks that server will buffer | 3.0 |
| sourceType | String | N/A | Must be "Push" or "Pull" which indicates how the publishing point ingests encoder stream | 3.0 |
| publishing | String | N/A | Comma separated string with optional values "Streams", "Archives" and "Fragments" indicating how this publishing point would publish the live data. e.g. " Fragments;Streams;Archives " | 3.0 |
| archivePath | String | N/A | If set, this path overwrites the default archive path set in the config. Note that server will not create the URL path hierarchy in the new path from this value. Users must not use the same archivePath for multiple publishing points. | 3.0 |
| startOnFirstRequest | Boolean | FALSE | Indicates whether the publishing point should automatically start upon the first request. | 3.0 |
| archiveSegmentLength | Uint32 | 0 | This specifies the archive segment length in seconds. Default value 0 means that a single smooth streaming presentation will be generated for the entire live broadcast. | 3.0 |
| manifestWindowLength | Uint32 | 0 | This specifies the DVR window in seconds. Default value 0 means the entire live broadcast will be available for DVR. | 3.0 |
| restartOnEncoderReconnect | Boolean | FALSE | This attribute is only applicable to publishing points with “Push” source type. If set, it allows the publishing point to be automatically shut down from “Stopped” state and restarted when new encoder streams come in. Note that this flag must be used together with startOnFirstRequest flag. Expression Encoder 4 does not work with option yet and the support will come in future releases. | 3.0 |
| formats | String |
N/A | Indicate additional output formats that the publishing point supports. In IIS Media Services 4.0, the only one supported is “m3u8-aapl” which is for Apple Live HTTP Streaming. | 4.0 |
| useEventIdInArchivePath | Boolean | FALSE | If set and the encoder is specifying Event ID on the POST URL, server will use the value of the Event ID as the name of the archive sub-folder for this publishing point session instead of using the auto-generated timestamp value. WARNING: Event ID must be unique for each live session. Otherwise the publishing point may fail to start due to name conflict of archive session directories. | 4.0 |
| sendEOSOnStop | Boolean | TRUE | This flag indicates whether the publishing point should send End-of-Stream (EOS) signal to downstream publishing points when stopping. Sending EOS signals will cause downstream publishing points going into “Stopped” state. Setting this flag to FALSE is useful when doing regular server maintenance on upstream servers when stopping downstream publishing points is not desirable. Downstream publishing points can be configured to automatically roll over to the backup server to continue streaming. | 4.0 |
| liveCacheSizeSec | Uint32 | 0 | This specifies how many latest fragments in live streaming, in duration of seconds, should be cached in the publishing point’s internal memory. Note that in normal case, the operating system’s file cache is doing the caching for reading and writing. This setting is useful when you want to guarantee memory caching for a specific publishing point so that clients following the live stream of that publishing point can get the best performance. | 4.0 |
| clientManifestVersion | Uint32 | 20 | For IISMS 4.0 release, the allowed values are “20” and “22”. “20” means 2.0 version of client manifest which is compatible with Smooth Streaming Client 1.0 and 1.1. “22” means 2.2 version of client manifest which supports a new manifest compression schema (require a new client update that will be released soon). | 4.0 |
