Amazon CloudFront
Developer Guide (API Version 2016-09-07)

Using an Amazon S3 Bucket as the Origin for an RTMP Distribution

When you create a distribution, you specify where CloudFront gets the files that it distributes to edge locations. For an RTMP distribution, you must use an Amazon S3 bucket; custom origins are not supported. To get your objects into your bucket, you can use any method supported by Amazon S3, for example, the Amazon S3 API or a third-party tool. You can create a hierarchy in your bucket just as you would with any other Amazon S3 bucket. You incur regular Amazon S3 charges for storing the objects in the bucket. For more information about the charges to use CloudFront, see CloudFront Reports.

Using an existing Amazon S3 bucket as your CloudFront origin server doesn't change the bucket in any way; you can still use it as you normally would to store and access Amazon S3 objects (at the normal Amazon S3 prices).

You can use the same Amazon S3 bucket for both RTMP and web distributions.


After you create an RTMP distribution, you can't change its origin server. If you need to change the Amazon S3 bucket for an RTMP distribution, you must create a new distribution that uses the new bucket and update either your links or your DNS records to use the domain name for the new distribution. You can then delete the original distribution. For more information, see Deleting a Distribution.

When you specify the name of the Amazon S3 bucket that you want CloudFront to get objects from, you generally use the following format:

If your bucket is in the US Standard region and you want Amazon S3 to route requests to a facility in Northern Virginia, use the following format:

Do not specify the name of the bucket using the following values:

  • The Amazon S3 path style,

  • The Amazon S3 CNAME, if any


For your bucket to work with CloudFront, the name must conform to DNS naming requirements. For more information, go to Bucket Restrictions and Limitations in the Amazon Simple Storage Service Developer Guide.
