Add custom ingest domains
With custom ingest domains, you can configure your RTMPS feeds to use an ingest URL that you specify instead of using live.cloudflare.com.
- Log in to your Cloudflare dashboard and select your account.
 - Click Stream > Live Inputs.
 - Click the Settings button above the list. The Custom Input Domains page displays.
 - Under Domain, add your domain and click Add domain.
 - At your DNS provider, add a CNAME record that points to 
live.cloudflare.com. If your DNS provider is Cloudflare, this step is done automatically. 
 Delete a custom domain
- From the Custom Input Domains page under Hostnames, locate the domain.
 - Click the menu icon under Action. Click Delete.
