StartChannelRequest

Request message for "LivestreamService.StartChannel".

Fields
name	string Required. The name of the channel resource, in the form of: projects/{project}/locations/{location}/channels/{channelId}.

The server will guarantee that for at least 60 minutes since the first request. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

position	NormalizedCoordinate Optional. Position of the image in terms of normalized coordinates of the upper-left corner of the image, based on output video resolution. For example, use the x and y coordinates {0, 0} to position the top-left corner of the overlay animation in the top-left corner of the output video.
