The RecordId should be less than 32 bytes. If you carry the RecordId and initiate the start recording request more than once, only one task will be started, and the second one will report the error FailedOperation.TaskExist.

PublishCdnParams.N	No	Array of McuPublishCdnParam	If you want to push the stream to a CDN, you can use the PublishCdnParams.N parameter to set it. It supports pushing streams to up to 10 CDN addresses simultaneously. If the relay address is a Tencent Cloud CDN, please explicitly set IsTencentCdn to 1.
ReadyTimeout	No	Integer	The timeout for loading page resources during recording, in seconds. The default value is 0 seconds. This value must be greater than or equal to 0 seconds and less than or equal to 60 seconds. If page load timeout detection is not enabled for the recording page, please do not set this parameter.
EmulateMobileParams	No	EmulateMobileParams	Render mobile mode parameters; do not set this parameter if you are not going to render mobile mode pages.

3. Output Parameters

Parameter Name	Type	Description
TaskId	String	The unique ID of the recording task
