Configuring Stream Delay

Notes

• You can configure the stream delay for RTMP and HTTP-FLV streams of the live app on the console. To configure the stream delay for other apps, submit a service ticket.
• The GOP of the streaming end cannot be greater than the configured delay. The actual delay is influenced by factors including the player's network conditions.
• After the stream delay is modified, you need to push the stream again for the modification to take effect.
• If the stream delay is set to 2s, the playback experience of HLS videos will be affected. For example, the playback will start in seconds. To avoid poor user experience, set a longer stream delay (4s or 6s).
• This function is not recommended for LLL.

Prerequisites

• The ingest domain name and streaming domain name have been added and associated.
• You have configured CNAME records at your domain names' DNS provider.

2. In the navigation pane, choose Domains.
3. Click Manage in the Operation column of the desired streaming domain name.

   Note: The actual livestream delay is also influenced by factors including the player's network conditions.
