The Cloud Streaming Services console provides the Live Video Caster (LVC) system. This document describes how to use LVC for online broadcasting after activating the LVC feature.
Note:
Billable items of LVC include broadcast output duration and third-party relay. Billing is based on usage duration. For more information, see Live Video Caster Pricing Overview.
LVC is incompatible with Internet Explorer and Firefox browsers. We recommend using Chrome.

Each account can create up to five LVC instances. If there are already five instances under your account, you must delete an existing instance before you can add a new one. To add more instances, please submit a ticket.
You can add up to five VOD files to the VOD input playback list.
Third-party relay supports up to three streams, one of which is relayed to the current CSS account by default, and the other two can be relayed to third-party vendors. For more information, see Relay.
