VideoApp Interface Reference | Alexa Skills Kit

The VideoApp interface provides the VideoApp.Launch directive for streaming native video files on Alexa-enabled devices with a screen. Your skill can send the VideoApp.Launch directive to launch a video. Your skill can send a launch directive in response to a voice request, or in response when a user taps a programmed item on the screen.

Not all devices support the

interface. Always check for

support in the

property in the incoming request before you attempt to send video content.

• Supported Video Formats and Resolutions
• VideoApp Features
• VideoApp as Seen on Alexa-enabled devices with a screen
• Configure Your Skill for the VideoApp Directives
• Implement VideoApp Directives
• Parameters of Response
• Service Interface Reference (JSON)

Supported video formats for VideoApp are shown in the following table.

In addition, follow these guidelines for any video referenced by the VideoApp directive:

• Provide an HTTPS URL to video content.
• Supported file extensions: .mp4, .m3u8, .ts
• MPEG4 or H.264 codec
• Recommended resolution (frame size): 640x480 or 1280x720
• Maximum resolution: 1280x720

Note: Echo Spot does not support 4K videos.

The VideoApp as seen on Alexa-enabled devices with a screen has the following features:

GUI features:

• Playback controls
• Title
• Subtitle

Voice Controls:

• Alexa, pause/resume
• Alexa, stop/close

On Echo Show and Fire TV Cube, the VideoApp screens will look similar to the following.

Native Video

Error

This table compares the default view of VideoPlayer on each device. Only Echo Show and Echo Spot are shown here.

The following images show Echo Spot video with various levels of zoom. The default display is "letterbox". The customer can change to the other levels of zoom.

With "letterbox" zoom, note that the video is scaled so that its width and height are fully within the screen.

This image shows full-screen video.

This image shows "pillowbox" video. Note that the height is scaled so as to fit completely within the screen vertically, but the horizontal dimension does not fit within the screen.

To use VideoApp directives for video playback, you must indicate that your skill implements this interface

1. In the developer console, navigate to Custom > Interfaces.
2. Enable the Video App option and then click Save Interfaces. Be sure to click Build Model to re-build your interaction model.

The standard built-in intents are implemented automatically, except that AMAZON.CancelIntent is not supported. They are described in Standard Intents. These standard built-in intents work with VideoApp:

• AMAZON.PauseIntent and AMAZON.StopIntent, which send the same message to the skill

• AMAZON.ResumeIntent

The VideoApp interface provides the VideoApp.Launch directive, which sends Alexa a command to stream the video file identified by the specified videoItem field.

The source for videoItem must be a native video file. Only one video item at a time may be supplied.

When including a directive in your skill service response, set the type property to the directive you want to send. Here is an example of a full response object sent from a LaunchRequest or IntentRequest.

In this example, one native-format video will be played.

{
  "version": "1.0",
  "sessionAttributes": null,
  "response": {
    "outputSpeech": null,
    "card": null,
    "directives": [
      {
        "type": "VideoApp.Launch",
        "videoItem": {
          "source": "https://www.example.com/video/sample-video-1.mp4",
          "metadata": {
            "title": "Title for Sample Video",
            "subtitle": "Secondary Title for Sample Video"
          }
        }
      }
    ],
    "reprompt": null
  }
}

For the full response format, see Response Body Syntax in the JSON Interface Reference for Custom Skills.

The back button is displayed on every VideoApp screen, and cannot be hidden, unlike for the Display interface. If clicked, the back button takes the customer to the previous display template in the current session. See Back Button in Display Templates.

See Response Body Syntax for more details. This section refers to the VideoApp-specific parameters of the response.

Important notes are as follows:

• Do not include a Display.RenderTemplate directive in the same response.
• Do not include the shouldEndSession parameter in the response, even if you set the value to null.

The following are sub-parameters of videoItem.

The following are sub-parameters of videoItem.metadata.
