Alexa.Presentation.APL.Video 1.0
The Alexa.Presentation.APL.Video interface is one of the APIs available for the Alexa Presentation Language (APL). This interface describes the video codecs that are supported by the APL runtime for a device. These codecs may differ from video codecs supported elsewhere on the device.
Publish the codec values based on both the base system and on the ability of APL to play the format.
To learn more about APL, its interfaces, and how to use those interfaces together, see Alexa Presentation Language (APL) Overview.
Capability assertion
Alexa.Presentation.APL.Video 1.0 may be implemented by the device on its own behalf, but not on behalf of any connected endpoints.
New AVS integrations must assert support through Alexa.Discovery, but Alexa will continue to support existing integrations using the Capabilities API.
