Merge and apply the config? [y/n]:

Only three configurations should be cared about: Channel Name (name), Channel State (state), Catchup Location (catchupLocation), others are meaningful for ew-live-ingest, another part of SW Live Ingest, so they should be left as default:

• Channel Name (name): have to be exactly the same with the channel name configured in ew-hlsingest, so that ew-cbm will know where to look for the input.
• Channel State (state): cbm-only is a must.
• Catchup Location (catchupLocation) (optional): is the location that ew-cbm will write the catch up buffer to, please refer to ew-cbm documentation to know how to configure it.

After done configuring, this command, ew-cb-media, can be used to check for the running channel. If the channel name appears in the output of that command and the duration of catchup buffer starts growing (repeat the command the see if the channel is growing, or just use watch ew-cb-media), then the live content can now be delivered through ew-cbm to repackager and beyond.
