Config class methods for tags

You can configure custom tag names in a stream with the MediaPlayerItemConfig class.

To create a new MediaPlayerItemConfig:

var mediaPlayerItemConfig = new AdobePSDK.MediPlayerItemConfig();

Here is some information about how the MediaPlayerItemConfig methods are used to manage custom tags:

Subscribe to specific custom tags
`var subscribeTagsObtained = mediaPlayerItemConfig.subscribeTags;`	Retrieves the current list of subscribed tags.
`var subscribeTags = ["#EXT-X-PROGRAM-DATE-TIME"];mediaPlayerItemConfig.subscribeTags = subscribeTags;`	Sets the list of subscribed tags exposed to the application. Your application is also automatically subscribed to all tags that are transmitted through adTags .
Customize the ad tags used by the default opportunity detector
`var adTagsObtained = mediaPlayerItemConfig.adTags;`	Retrieves the current list of ad tags.
`var adTags = ["#EXT-X-CUE"];mediaPlayerItemConfig.adTags = adTags;`	Sets the list of ad tags to be used by the default opportunity generator.

Remember the following:

The custom tag name must contain the # prefix.

For example, #EXT-X-ASSET is a correct custom tag name, but EXT-X-ASSET is incorrect.
You cannot change the configuration after the media stream has been loaded.
