Live events - Create – Ravnur

AMS compatibility note
RMS accepts a small set of AMS fields to keep SDK and payload compatibility.

Labelling legend:

[No-op in RMS] – accepted for AMS compatibility; ignored by RMS, meaning that they can be omitted as changes to them will not affect live events' behavior.
[Not emitted by RMS] – present in AMS docs; RMS never returns this value.

Create live event
Creates a new live event.

PUT https://{{api-endpoint}}/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Media/mediaservices/{accountName}/liveEvents/{liveEventName}?api-version={api-version}

URI Parameters

Name	In	Required	Type	Description
`accountName`	path	True	string	The RMS account name.
`LiveEventName`	path	True	string	The name of the live event, maximum length is 32. Regex pattern: `^[a-zA-Z0-9]+(-[a-zA-Z0-9])$`
`resourceGroupName`	path	True	string	The name of the resource group within the Azure subscription.
`subscriptionId`	path	True	string	The unique identifier for a Microsoft Azure subscription.
`api-version`	query	True	string	The version of the API to be used with the client request. Required for compatibility; any value accepted; no effect.
`autoStart`	query		boolean	[No-op in RMS] (Not used). The flag indicates if the resource should be automatically started on creation.

Request Body

Name	Required	Type	Description
location	True	string	Azure region field is accepted for AMS compatibility, but has no effect in RMS. Required for compatibility; any value accepted; no effect.
properties.input	True	LiveEventInput	Live event input settings. It defines how the live event receives input from a contribution encoder.
properties.description		string	A description for the live event.
properties.encoding		LiveEventEncoding	Encoding settings for the live event. It configures whether a live encoder is used for the live event and settings for the live encoder if it is used.
properties.streamOptions		string[]	The options to use for the LiveEvent. This value is specified at creation time and cannot be updated. The valid values for the array entry values are 'Default' and 'LowLatency'. `LowLatency` is not applicable to RTSP Pull/Push. When `LowLatency` is set, DVR is disabled during live streaming but recording continues for VOD.
tags		object	Resource tags.
properties.crossSiteAccessPolicies		CrossSiteAccessPolicies	[No-op in RMS] Live event cross site access policies. Legacy Silverlight XML. Omit.
properties.hostnamePrefix		string	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, when `useStaticHostname` is `true`, this is the first part of the static hostname for preview/ingest endpoints (combined with the Media Services account name and a regional code). RMS does not allocate static hostnames, so this value is ignored and has no effect on endpoint URLs. Any value is accepted; you may omit it. RMS does not separate “preview” and “broadcast” endpoints. The same ingest/output link is used for both previewing and streaming live content. All `preview`-related parameters from AMS are ignored and have been removed from this API reference.
properties.transcriptions		LiveEventTranscription[]	[No-op in RMS] Live transcription settings for the live event. See https://go.microsoft.com/fwlink/?linkid=2133742 for more information about the live transcription feature. Live transcription is in development by RMS.
properties.useStaticHostname		boolean	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, when `useStaticHostname` is `true`, this is the first part of the static hostname for preview/ingest endpoints (combined with the Media Services account name and a regional code). RMS does not allocate static hostnames, so this value is ignored and has no effect on endpoint URLs. Any value is accepted; you may omit it. RMS does not separate “preview” and “broadcast” endpoints.

properties.hostnamePrefix	string	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, when `useStaticHostname` is `true`, this is the first part of the static hostname for preview/ingest endpoints (combined with the Media Services account name and a regional code). RMS does not allocate static hostnames, so this value is ignored and has no effect on endpoint URLs. Any value is accepted; you may omit it. RMS does not separate “preview” and “broadcast” endpoints. The same ingest/output link is used for both previewing and streaming live content. All `preview`-related parameters from AMS are ignored and have been removed from this API reference.

properties.useStaticHostname	boolean	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, when `useStaticHostname` is `true`, this is the first part of the static hostname for preview/ingest endpoints (combined with the Media Services account name and a regional code). RMS does not allocate static hostnames, so this value is ignored and has no effect on endpoint URLs. Any value is accepted; you may omit it. RMS does not separate “preview” and “broadcast” endpoints. The same ingest/output link is used for both previewing and streaming live content. All `preview`-related parameters from AMS are ignored and have been removed from this API reference.

LiveEventEncoding

Specifies the live event type and optional encoding settings for encoding live events.

Name	Type	Description
encodingType	LiveEventEncodingType	Live event type. When encodingType is set to PassthroughStandard, the service simply passes through the incoming video and audio layer(s) to the output. When encodingType is set to Standard or Premium1080p, a live encoder transcodes the incoming stream into multiple bitrates or layers. This property cannot be modified after the live event is created.
isDVRSource	boolean	[No-op in RMS] Enable/disable DVR functionality. Value is unconditionally overwritten on create and recomputed on any StreamOptions change from the account-level. To create a no-DVR account, Ravnur support.
keyFrameInterval	string	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, this sets the output fragment length (and video key-frame interval/GoP) for encoding live events (not pass-through), using an ISO-8601 duration (e.g., `PT2S`). RMS ignores this field and uses service defaults; supplying a value has no effect and may be omitted.
presetName	string	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, this optional preset applies when `encodingType` ≠ `None` and is immutable after creation (defaults: `Default720p` for `Standard`, `Default1080p` for `Premium1080p`). RMS does not apply AMS encoding presets; the value is ignored.
stretchMode	stretchMode	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, controls how input video is resized to match output resolutions (e.g., `None`, `AutoFit`, `AutoSize`). RMS does not use this setting; scaling/letterboxing behavior is determined by the RMS pipeline. Providing this field has no effect.

LiveEventEncodingType

Live event type. When encodingType is set to or PassthroughStandard, the service simply passes through the incoming video and audio layer(s) to the output. When encodingType is set to Standard or Premium1080p, a live encoder transcodes the incoming stream into multiple bitrates or layers. This property cannot be modified after the live event is created.

Name	Type	Description
PassthroughStandard	string	The ingested stream passes through the live event from the contribution encoder without any further processing.
Premium1080p	string	A contribution live encoder sends a single bitrate stream to the live event and RMS creates multiple bitrate streams. The output cannot exceed 1080p in resolution.
Standard	string	A contribution live encoder sends a single bitrate stream to the live event and RMS creates multiple bitrate streams. The output cannot exceed 720p in resolution.

streamingProtocol	LiveEventInputProtocol	The input protocol for the live event. This is specified at creation time and cannot be updated.
keyFrameIntervalDuration	string	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, this defined an ISO 8601 duration that controlled the segment duration in the HLS output. RMS does not use this setting; providing this field has no effect.
accessControl	LiveEventInputAccessControl	[No-op in RMS] Accepted for AMS payload compatibility. In AMS, controls how input video is resized to match output resolutions (e.g., `None`, `AutoFit`, `AutoSize`). RMS does not use this setting; scaling/letterboxing behavior is determined by the RMS pipeline. Providing this field has no effect.
timedMetadataEndpoints	LiveEventTimedMetadataEndpoint[]	[No-op in RMS] Accepted for AMS payload compatibility. In AMS this lists endpoints for timed metadata injection/relay (e.g., ID3/SCTE-35). RMS does not use or emit timed metadata via this array; values are ignored and may be omitted.

Name	Type	Description
srtStreamId	string	SRT-only and entirely server-generated. The SRT stream ID used to identify and route the ingest stream. This is an arbitrary string the encoder embeds in the SRT handshake, allowing the server to distinguish multiple streams on the same endpoint.
srtPassphrase	string	Server-generated (set to the OME proxy passphrase or, in non-proxy mode, the internal SrtNodePassphrase) and stored/surfaced via the SrtPassphrase tag - any client-supplied value is overwritten on create and immutable on update. Optional passphrase for SRT streams.
srtNodePassphrase	string	Server-generated on create as a random 12-char value. The passphrase for the SRT relay node. This is used for securing the hop between the ingest edge node and the internal processing node, analogous to `srtPassphrase` but scoped to the node-level leg of the connection.

Auto-set on create from the 'live.srt.maxbw' server setting (default 50000000); any client-supplied value is unconditionally overwritten and immutable on update (SRT input is not modified in the server). Can be modified via Ravnur support request for all new SRT live events.

LiveEventRTSPPullProtocol

The input protocol for the live event. This is specified at creation time and cannot be updated.

RTSP Pull parameters must be specified in two locations in the request body:

In tags - IngestOptions.rtspPullUrl and IngestOptions.rtspPullMode.

Specifies how the input video will be resized to fit the desired output resolution(s). Default is None.

Name	Type	Description
AutoFit	string	Pad the output (with either letterbox or pillar box) to honor the output resolution, while ensuring that the active video region in the output has the same aspect ratio as the input. For example, if the input is 1920x1080 and the encoding preset asks for 1280x1280, then the output will be at 1280x1280, which contains an inner rectangle of 1280x720 at aspect ratio of 16:9, and pillar box regions 280 pixels wide at the left and right.
AutoSize	string	Override the output resolution, and change it to match the display aspect ratio of the input, without padding. For example, if the input is 1920x1080 and the encoding preset asks for 1280x1280, then the value in the preset is overridden, and the output will be at 1280x720, which maintains the input aspect ratio of 16:9.
None	string	Strictly respects the output resolution specified in the encoding preset without considering the pixel aspect ratio or display aspect ratio of the input video.
