## Properties
<a name="aws-properties-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-properties"></a>

`ChildManifestName`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-childmanifestname"></a>
The name of the child manifest associated with the low-latency HLS (LL-HLS) manifest configuration of the origin endpoint.  
*Required*: No  
*Type*: String  
*Pattern*: `^[a-zA-Z0-9_-]+$`  
*Minimum*: `1`  
*Maximum*: `256`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`FilterConfiguration`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-filterconfiguration"></a>
Filter configuration includes settings for manifest filtering, start and end times, and time delay that apply to all of your egress requests for this manifest.   
*Required*: No  
*Type*: [FilterConfiguration](aws-properties-mediapackagev2-originendpoint-filterconfiguration.md)  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ManifestName`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-manifestname"></a>
A short string that's appended to the endpoint URL. The manifest name creates a unique path to this endpoint. If you don't enter a value, MediaPackage uses the default manifest name, `index`. MediaPackage automatically inserts the format extension, such as `.m3u8`. You can't use the same manifest name if you use HLS manifest and low-latency HLS manifest. The `manifestName` on the `HLSManifest` object overrides the `manifestName` you provided on the `originEndpoint` object.  
*Required*: Yes  
*Type*: String  
*Pattern*: `^[a-zA-Z0-9_-]+$`  
*Minimum*: `1`  
*Maximum*: `256`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ManifestWindowSeconds`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-manifestwindowseconds"></a>
The total duration (in seconds) of the manifest's content.  
*Required*: No  
*Type*: Integer  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ProgramDateTimeIntervalSeconds`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-programdatetimeintervalseconds"></a>
Inserts `EXT-X-PROGRAM-DATE-TIME` tags in the output manifest at the interval that you specify. If you don't enter an interval, `EXT-X-PROGRAM-DATE-TIME` tags aren't included in the manifest. The tags sync the stream to the wall clock so that viewers can seek to a specific time in the playback timeline on the player.  
Irrespective of this parameter, if any `ID3Timed` metadata is in the HLS input, MediaPackage passes through that metadata to the HLS output.  
*Required*: No  
*Type*: Integer  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ScteHls`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-sctehls"></a>
The SCTE-35 HLS configuration associated with the low-latency HLS (LL-HLS) manifest configuration of the origin endpoint.  
*Required*: No  
*Type*: [ScteHls](aws-properties-mediapackagev2-originendpoint-sctehls.md)  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`StartTag`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-starttag"></a>
To insert an EXT-X-START tag in your HLS playlist, specify a StartTag configuration object with a valid TimeOffset. When you do, you can also optionally specify whether to include a PRECISE value in the EXT-X-START tag.  
*Required*: No  
*Type*: [StartTag](aws-properties-mediapackagev2-originendpoint-starttag.md)  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`Url`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-url"></a>
The URL of the low-latency HLS (LL-HLS) manifest configuration of the origin endpoint.  
*Required*: No  
*Type*: String  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`UrlEncodeChildManifest`  <a name="cfn-mediapackagev2-originendpoint-lowlatencyhlsmanifestconfiguration-urlencodechildmanifest"></a>
When enabled, MediaPackage URL-encodes the query string for API requests for LL-HLS child manifests to comply with Amazon Signature Version 4 (SigV4) signature signing protocol. For more information, see [Amazon Signature Version 4 for API requests](https://docs.amazonaws.cn/IAM/latest/UserGuide/reference_sigv.html) in *Amazon Identity and Access Management User Guide*.  
*Required*: No  
*Type*: Boolean
