Using DVR playback

This tutorial shows how to properly configure DVR playback on AMP.

  1. Pre-requisites
  2. Enabling DVR mode
  3. Media Temporal Types

1. Pre-requisites

In order to leverage player's API the stream must have a valid sliding window regardless the format HLS or Dash, most of the live streams do not have this feature enabled by default and may depend on the CDN capabilities.

2. Enabling DVR mode

AMP does provide a player API to properly handle the DVR stream playback, progress on the sliding window and a featured player UI.

In order to enable DVR mode on AMP the "temporalType" attribute on the media configuration object should be set to "dvr" as follow.

var config = {
  media: {
	    guid: "Video 1",
		title: "Windowed DVR",
		temporalType: "dvr",
		source: [{
			src: "http://mcqalivesmdvr1-f.akamaihd.net/i/mav001_1@22121/index_800_av-p.m3u8?sd=10&dw=600&rebase=on",
			type: "application/x-mpegURL"
		}]
};

3. Media Temporal Types

The values for temporalType represent the following functionality:

  • "vod": Used for most of finite streams, i.e. clips, movies, series.
  • "live": Stream will be set on the edge and most of the player controls will be prohibited, i.e seeking, rewind, and forward jumping.
  • "dvr": Allows users to move through the sliding window during live streaming.

Note: If the temporal type is not provided, the player will detect and choose between live and vod, but not for dvr.
