Time shifting

1. Log on to the ApsaraVideo Live console.

2. In the left-side navigation pane, choose Feature Management > Time Shifting to go to the Time Shifting page.

3. Select the streaming domain that you want to configure.

4. Click Add.

5. Configure time shifting.

   The following table describes the parameters for the time shifting configuration.

   Parameter	Description
   AppName	The application name. This configuration takes effect only when the AppName matches the AppName used for stream ingest. The name can be up to 255 characters in length and can contain digits, uppercase letters, lowercase letters, hyphens (-), and underscores (_). Hyphens and underscores cannot be at the beginning of the name. To configure time shifting at the domain level, enter an asterisk (*).
   Stream Name	The stream name.
   Time-shift Scope	Original Only: Only the original stream supports time shifting. Original & Transcoded: Both original and transcoded streams support time shifting.
   Retention Period	ApsaraVideo Live offers the following retention periods: 1 day 3 days 7 days 15 days 30 days

   Note

   • After you configure time shifting, you must re-ingest the stream for the configuration to take effect.

   • You can directly access the time-shifted stream by using the URL that corresponds to the streaming domain. For more information about the URL specifications, see Time shifting rules.

   • If a primary streaming domain is associated with a sub-streaming domain, you must enable time shifting for the sub-streaming domain. Otherwise, the time shifting configuration does not take effect for the sub-streaming domain.

6. Click OK.
