Managing Channels

Procedure

1. Log in to the Live console.
2. In the navigation pane on the left, choose Channels under Media Live.
3. Perform the following operations as required.
   • Starting a channel

     Click Start in the Operation column to start the channel.

   • Stopping a channel

     Click Stop in the Operation column to stop the channel.

   • Modifying a channel

     Click Manage in the Operation column to modify the channel information.

     If you select multiple transcoding templates when modifying the channel, all transcoding templates must meet the following conditions:

     • Each template must use a different video bitrate.
     • The settings of Use Source I-Frame, GOP Unit, GOP Size, and Video Frame Rate must be identical across all selected templates.
     • If a template is modified during live transcoding and this results in mismatched GOP size, GOP unit, or video frame rate settings across templates, no output stream will be generated.
     • If Use Source I-Frame is disabled, the channel supports only one input and up to six outputs.

     You need to restart the channel for the modification to take effect. If the channel has been started, it will automatically restart after the modification. This restart takes about 30 seconds.

     Note: The restart operation will interrupt the connection to the headend encoder, and consequently interrupt the media stream. You will need to manually push the stream again after the restart is complete.

   • Viewing the configuration and running status of a channel

     Click the channel ID or View Details in the Operation column. The channel details page is displayed, where you can view the basic information and running status of the channel, as shown in Figure 1.

   • Deleting a channel

     Stop the channel and then choose More > Delete in the Operation column to delete the channel. If there is an ongoing live-to-VOD task in the channel, the channel cannot be deleted until the task is completed.
