create_streaming_distribution#

Creates a new RTMP distribution. An RTMP distribution is similar to a web distribution, but an RTMP distribution streams media files using the Adobe Real-Time Messaging Protocol (RTMP) instead of serving files using HTTP.
To create a new distribution, submit a POST request to the CloudFront API version/distribution resource. The request body must include a document with a StreamingDistributionConfig element. The response echoes the StreamingDistributionConfig element and returns other information about the RTMP distribution.
To get the status of your request, use the GET StreamingDistribution API action. When the value of Enabled is true and the value of Status is Deployed, your distribution is ready. A distribution usually deploys in less than 15 minutes.
For more information about web distributions, see Working with RTMP Distributions in the Amazon CloudFront Developer Guide.
Beginning with the 2012-05-05 version of the CloudFront API, we made substantial changes to the format of the XML document that you include in the request body when you create or update a web distribution or an RTMP distribution, and when you invalidate objects. With previous versions of the API, we discovered that it was too easy to accidentally delete one or more values for an element that accepts multiple values, for example, CNAMEs and trusted signers. Our changes for the 2012-05-05 release are intended to prevent these accidental deletions and to notify you when there's a mismatch between the number of values you say you're specifying in the Quantity element and the number of values specified.

When you update your distribution by using this API action, follow the steps here to get the current configuration and then make your updates, to make sure that you include all of the required fields. To view a summary, see Required Fields for Create Distribution and Update Distribution in the Amazon CloudFront Developer Guide.
The update process includes getting the current distribution configuration, updating the XML document that is returned to make your changes, and then submitting an UpdateDistribution request to make the updates.
For information about updating a distribution using the CloudFront console instead, see Creating a Distribution in the Amazon CloudFront Developer Guide.
To update a web distribution using the CloudFront API
Submit a GetDistributionConfig request to get the current configuration and an Etag header for the distribution. If you update the distribution again, you must get a new Etag header.
Update the XML document that was returned in the response to your GetDistributionConfig request to include your changes. When you edit the XML file, be aware of the following: You must strip out the ETag parameter that is returned. Additional fields are required when you update a distribution. There may be fields included in the XML file for features that you haven't configured for your distribution. This is expected and required to successfully update the distribution. You can't change the value of CallerReference. If you try to change this value, CloudFront returns an IllegalUpdate error. The new configuration replaces the existing configuration; the values that you specify in an UpdateDistribution request are not merged into your existing configuration. When you add, delete, or replace values in an element that allows multiple values (for example, CNAME), you must specify all of the values that you want to appear in the updated distribution. In addition, you must update the corresponding Quantity element.
Submit an UpdateDistribution request to update the configuration for your distribution: In the request body, include the XML document that you updated in Step 2. The request body must include an XML document with a DistributionConfig element. Set the value of the HTTP If-Match header to the value of the ETag header that CloudFront returned when you submitted the GetDistributionConfig request in Step 1.
Review the response to the UpdateDistribution request to confirm that the configuration was successfully updated.
Optional: Submit a GetDistribution request to confirm that your changes have propagated. When propagation is complete, the value of Status is Deployed.
