Performs a specific action on a stream, such as publishing or stopping.
Actions change the stream's state without modifying its content or metadata.

gRPC request

rpc PerformAction (PerformStreamActionRequest) returns (operation.Operation)

PerformStreamActionRequest

{
  "stream_id": "string",
  // Includes only one of the fields `publish`, `stop`
  "publish": "PublishAction",
  "stop": "StopAction"
  // end of the list of possible fields
}

Field	Description
stream_id	string Required field. ID of the stream on which to perform the action. The maximum string length in characters is 50.
publish	PublishAction Publish the stream, changing its status from READY to ONAIR. This makes the stream available for watching. Includes only one of the fields `publish`, `stop`. Specifies which action to perform on the stream (exactly one must be chosen).
stop	StopAction Stop the stream, changing its status to FINISHED. This terminates the streaming session and releases resources. Includes only one of the fields `publish`, `stop`. Specifies which action to perform on the stream (exactly one must be chosen).

PublishAction

Parameters for the publish action.
The action changes the stream's status from READY to ONAIR.

Field	Description
Empty

StopAction

Parameters for the stop action.
The action changes the stream's status to FINISHED.

Field	Description
Empty

An Operation resource. For more information, see Operation.

Field	Description
id	string ID of the operation.
description	string Description of the operation. 0-256 characters long.
created_at	google.protobuf.Timestamp Creation timestamp.
created_by	string ID of the user or service account who initiated the operation.
modified_at	google.protobuf.Timestamp The time when the Operation resource was last modified.
done	bool If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available.
metadata	PerformStreamActionMetadata Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
error	google.rpc.Status The error result of the operation in case of failure or cancellation. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.
response	Stream The normal response of the operation in case of success. If the original method returns no data on success, such as Delete, the response is google.protobuf.Empty. If the original method is the standard Create/Update, the response should be the target resource of the operation. Any method that returns a long-running operation should document the response type, if any. Includes only one of the fields `error`, `response`. The operation result. If `done == false` and there was no failure detected, neither `error` nor `response` is set. If `done == false` and there was a failure detected, `error` is set. If `done == true`, exactly one of `error` or `response` is set.

PerformStreamActionMetadata

Field

Description

stream_id

string

ID of the stream on which the action is being performed.
This identifier can be used to track the action operation
and to verify that the action is being applied to the correct stream.

Stream

Entity representing a live video stream.
A stream is a real-time video broadcast linked to a specific stream line.

Field	Description
id	string Unique identifier of the stream.
channel_id	string Identifier of the channel where the stream is created and managed.
line_id	string Identifier of the stream line to which this stream is linked.
title	string Title of the stream displayed in interfaces and players.
description	string Detailed description of the stream content and context.
thumbnail_id	string Identifier of the thumbnail image used to represent the stream visually.
status	enum StreamStatus Current status of the stream. `STREAM_STATUS_UNSPECIFIED`: The stream status is not specified. `OFFLINE`: The stream is offline and not broadcasting. `PREPARING`: The system is preparing the infrastructure for receiving the video signal. `READY`: The infrastructure is ready to launch the stream. `ONAIR`: The stream is currently broadcasting live. `FINISHED`: The stream has completed and is no longer broadcasting.
start_time	google.protobuf.Timestamp Timestamp when the stream was initiated.
publish_time	google.protobuf.Timestamp Timestamp when the stream was published (switched to ONAIR status).
finish_time	google.protobuf.Timestamp Timestamp when the stream was completed.
auto_publish	google.protobuf.BoolValue Controls automatic publishing of the stream when it's ready. When set to true, automatically switches status from READY to ONAIR.
on_demand	OnDemand On-demand stream starts immediately when a video signal appears. Includes only one of the fields `on_demand`, `schedule`. Specifies the stream scheduling type.
schedule	Schedule Scheduled stream starts and finishes at specified time. Includes only one of the fields `on_demand`, `schedule`. Specifies the stream scheduling type.
created_at	google.protobuf.Timestamp Timestamp when the stream was initially created in the system.
updated_at	google.protobuf.Timestamp Timestamp of the last modification to the stream or its metadata.
labels	object (map<string, string>) Custom user-defined labels as `key:value` pairs. Maximum 64 labels per stream. Used for organization, filtering, and metadata purposes. Labels can be used for organization, filtering, and metadata purposes.

OnDemand

Represents an on-demand stream type.
This type of stream must be started and finished explicitly by the user.
It begins broadcasting immediately when a video signal is detected.

Field	Description
Empty

Schedule

Represents a scheduled stream type.
This type of stream starts and finishes automatically at specified time.

Field

Description

start_time

google.protobuf.Timestamp

Scheduled time when the stream should automatically start.

finish_time

google.protobuf.Timestamp

Scheduled time when the stream should automatically finish.
