Use a custom domain for live streaming
Use your own domain instead of global-live.mux.com for live streaming ingest. Also known as CNAME-ing or "canonical naming" global-live.mux.com.
In this guide:
CNAME-ing, short for "Canonical Naming", is a configuration that allows you to change the default name we provide.
To use your own domain instead of global-live.mux.com for live streaming, all you need to do is add a CNAME to your domain's DNS settings that points to global-live.mux.com.
RTMP vs. RTMPS with custom domains
Mux supports both RTMP and RTMPS entry points. Live streams are published at global-live.mux.com.
RTMP supports using custom domains. Custom domains will not work for RTMPS and stream.mux.com (playback URLs).
Please reach out to help@mux.com with additional details of your requirements.
Here are a few popular domain services with CNAME-ing instructions. If your domain service is not listed, try searching their support resources.
To show an example of a domain service that offers CNAME configurations, this is what a GoDaddy configuration looks like after it has been edited to include the live.mux.com name.
Note that the CNAME doesn't have to be live or global-live, it can be anything you want it to be.
After configuring your DNS settings it may take a few hours before the new configuration works, depending on your DNS provider.
Migrate from live.mux.com
There are a few differences between live.mux.com and global-live.mux.com:
- you should see much better performance globally using the new endpoint,
- but it also supports RTMPS. For security reasons RTMPS is greatly preferred (think HTTPS vs HTTP), but some clients may not handle the secure protocol well. For those clients you can specify the port
5222.
We don't currently offer a way of creating a CNAME for RTMPS, but you can replicate the existing behavior of live.mux.com over RTMP with the added port.
Here are a few examples of RTMPS and RTMP CNAME URLs before and after they are changed to custom domains:
# RTMPS examples rtmps://global-live.mux.com:443/app # RTMP examples rtmp://global-live.mux.com:5222/app rtmp://your-cname.your-site.com:5222/app
