Time Shifting Details
Tencent Cloud Live Broadcast supports time-shift management through index information, including functions such as viewing time-shift details, configuring time-shift playback, and live broadcast editing.
Prerequisites
You have logged in to the CSS console.
You have created a time shifting template, bound it to a push domain, and successfully pushed a stream.
To use the live video editing and solidification capability, please make sure that you have activated the Tencent Cloud MPS. The solidified content will be stored in the COS service, and activating the MPS service will automatically activate the COS service.
Index Information Operation Guide
Directions
1. Click Feature Configuration > Time Shifting on the left sidebar and select the Time shifting details tab.
2. Select a domain or enter a stream ID, specify the time period (cannot be longer than 24 hours), and click Query.
3. Click Details to enter the details page.
4. View the push URL and stream type in the Basic Info area.
5. You can move the mouse over the timeline in the Index Details page to view the position and time. By clicking on the timeline, you can mark the time.

Note:
To preview time-shifted content, the domain used for playback must have an HTTPS certificate. If your playback domain does not have an HTTPS certificate yet, add one in Domain Management> Certificate Management. Using the time shifting feature will incur playback traffic/bandwidth fees.
