Collect the information for standard MediaPackage

For standard MediaPackage, the two URLs for a channel look like these examples:

6d2c.mediapackage.us-west-2.amazonaws.com/in/v2/9dj8/9dj8/channel

6d2c.mediapackage.us-west-2.amazonaws.com/in/v2/9dj8/e333/channel

Where:

mediapackage indicates that the input endpoints uses version 1 of the MediaPackage API

channel always appears at the end of the URL. It is the base filename for all the files for this destination.

The two URLs are always identical except for the folder just before channel.
