DVR Playback

DVR playback allows your clients to pause/resume, rewind, and fast forward a live stream, regardless of when that player connected to the stream. In other words, the starting point for DVR playback is determined by when your encoder starts pushing encoded video to the ingest point. The length of time that a video can be paused or to which it can be rewound depends on the value assigned to the DVR Duration option for the desired publishing point. In other words, the assigned value determines the number of minutes for the sliding window that will be available for DVR playback. Once the set amount of time has elapsed, content older than the specified time span will no longer be available for viewing.

Key information:

• The maximum amount of time for DVR playback is 240 minutes. By extension, a file chunk’s max-age is also limited to 240 minutes.
• The DVR Duration option determines the default max-age that will be assigned to file chunks generated for client requests. However, a rule can be created through HTTP Rules Engine that overrides this setting. This type of configuration is not recommended.
• It may take up to 10 minutes before changes to the DVR duration of a publishing point takes effect.
