LiveBroadcasts: transition

Changes the status of a YouTube live broadcast and initiates any processes associated with the new status. For example, when you transition a broadcast's status to testing, YouTube starts to transmit video to that broadcast's monitor stream. Before calling this method, you should confirm that the value of the status.streamStatus property for the stream bound to your broadcast is active.

Parameters
Required parameters
`broadcastStatus`	`string` The `broadcastStatus` parameter identifies the state to which the broadcast is changing. Note that to transition a broadcast to either the `testing` or `live` state, the `status.streamStatus` must be `active` for the stream that the broadcast is bound to. Acceptable values are: `complete` – The broadcast is over. YouTube stops transmitting video. `live` – The broadcast is visible to its audience. YouTube transmits video to the broadcast's monitor stream and its broadcast stream. `testing` – Start testing the broadcast. YouTube transmits video to the broadcast's monitor stream. Note that you can only transition a broadcast to the `testing` state if its `contentDetails.monitorStream.enableMonitorStream` property is set to `true`.
`id`	`string` The `id` parameter specifies the unique ID of the broadcast that is transitioning to another status.
`part`	`string` The `part` parameter specifies a comma-separated list of one or more `liveBroadcast` resource properties that the API response will include. The `part` names that you can include in the parameter value are `id`, `snippet`, `contentDetails`, and `status`.
Optional parameters
`onBehalfOfContentOwner`	`string` This parameter can only be used in a properly authorized request. Note: This parameter is intended exclusively for YouTube content partners. The `onBehalfOfContentOwner` parameter indicates that the request's authorization credentials identify a YouTube CMS user who is acting on behalf of the content owner specified in the parameter value. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and get access to all their video and channel data, without having to provide authentication credentials for each individual channel. The CMS account that the user authenticates with must be linked to the specified YouTube content owner.
`onBehalfOfContentOwnerChannel`	`string` This parameter can only be used in a properly authorized request. This parameter can only be used in a properly authorized request. Note: This parameter is intended exclusively for YouTube content partners. The `onBehalfOfContentOwnerChannel` parameter specifies the YouTube channel ID of the channel to which a video is being added. This parameter is required when a request specifies a value for the `onBehalfOfContentOwner` parameter, and it can only be used in conjunction with that parameter. In addition, the request must be authorized using a CMS account that is linked to the content owner that the `onBehalfOfContentOwner` parameter specifies. Finally, the channel that the `onBehalfOfContentOwnerChannel` parameter value specifies must be linked to the content owner that the `onBehalfOfContentOwner` parameter specifies. This parameter is intended for YouTube content partners that own and manage many different YouTube channels. It allows content owners to authenticate once and perform actions on behalf of the channel specified in the parameter value, without having to provide authentication credentials for each separate channel.
