Background information
A production studio in playlist mode allows you to aggregate multiple episodes with efficiency, create live channels in playlist mode, manage playlists, and edit the content of episodes. This helps meet your specific requirements in different business scenarios in a flexible, easy, and collaborative manner. Follow this topic to learn how to configure a production studio in playlist mode and use it for live streaming.
You can add up to 1,000 episodes to a production studio in playlist mode.
You can also call API operations to configure and use a production studio in playlist mode. For more information, see API guide.
Operations in the console
In the console, you can add media assets such as on-demand videos, images, and live streams. You can also specify the playback duration and sort the episodes to be played. After you add multiple media assets, you can start the playback with efficiency. During the playback, you can adjust the sequence of episodes in the playlist and add or remove episodes in real time.
The procedure varies based on whether you want to configure a production studio immediately after you create it.
If you want to configure a production studio immediately after you create it, start from Step 2.
If you already have a production studio and want to use the production studio for live streaming, start from Step 1.
Log on to the ApsaraVideo Live console. In the left-side navigation pane, click Production Studios.
Find the desired production studio in playlist mode and click Open.
When you create a production studio and enter the production studio page for the first time, the Studio Settings dialog box appears. You can also click Live Stream Settings in the upper-right corner of the production studio page to open the Studio Settings dialog box.

Multi-way Stream Relay
Optional. Click Add URL to add a relay URL.
ImportantAfter you add or delete a relay URL, the stream relay settings take effect only after you restart PGM.
If your live stream uses the features of a third-party platform, you are charged additional fees for stream relay. By default, there are three relay URLs that are free of charge under a domain name. If you specify more than three relay URLs, you are charged for the excess relay URLs. The pricing is the same as that of live center stream relay in ApsaraVideo Live.
