Live and VOD manifest reference - AWS Elemental MediaPackage
When a manifest is VOD

Live and VOD manifest reference

AWS Elemental MediaPackage delivers live and video on demand (VOD) manifests to requesting devices. A live manifest indicates that the content isn't complete. New content continually becomes available through the playback endpoint. Alternatively, a VOD manifest indicates that the program is complete, or will be complete at a specified time in the future.

This section describes the differences in live and VOD manifests, and explains when MediaPackage delivers each manifest type.

When a manifest is VOD

MediaPackage delivers a VOD manifest when the content of the program is complete. MediaPackage considers a program complete under the following conditions:

There's an end parameter in the past.

When a playback request includes an end parameter that's set in the past, the content is complete. No new content is added to it. MediaPackage delivers a static, VOD manifest to downstream devices.

For information about start and end parameters in playback requests, see Time-shifted viewing reference in AWS Elemental MediaPackage.

The manifest that the upstream encoder delivers to MediaPackage includes an EXT-X-ENDLIST tag.

When you stop the output from your encoder, the manifest that it sends to MediaPackage includes an EXT-X-ENDLIST tag. This tag tells MediaPackage that the content is complete, and no new content will be added. MediaPackage delivers a static, VOD manifest to downstream devices.

Note

If you manually stop an AWS Elemental MediaLive channel when one or both pipelines to MediaPackage are stopped, MediaLive doesn't include EXT-X-ENDLIST in the HLS manifest to MediaPackage. MediaPackage continues to produce a live manifest.

If both pipelines are active when you stop the channel, MediaLive includes EXT-X-ENDLIST. MediaPackage delivers a VOD manifest to downstream devices.

If you restart the output from the encoder, the manifest from MediaPackage becomes live again. Playback devices might need to refresh to resume content playback.

If you're using input redundancy and the active stream ends, MediaPackage fails over to the other incoming stream for input. The manifest isn't marked as complete unless both incoming streams end.
