Save the channel
You can save the channel only after you have configured and created everything that you need.
To save (create) the channel, choose Create channel in the navigation pane.
As soon as you choose Create channel, MediaLive validates the configuration of the channel and displays messages for any errors. You can't save a draft of the channel, and you can't save a channel that contains error messages.
To find your newly created channel, in the navigation pane, choose Channel. (The navigation pane might be collapsed. To open it, choose the menu icon in the upper-left corner of the console).
The Channel pane appears and shows the newly created channel in the list of channels. The state changes to Creating, and then to Ready.
