NS_E_MULTICAST_DISABLED
NS_E_MULTICAST_DISABLED: network-stage diagnosis
NS_E_MULTICAST_DISABLED (0xC00D2EE9) means the selected content requires multicast reception while multicast is disabled for the client or playback path.
Evidence to preserve
Record the stream URL/protocol, multicast requirement and the client/player configuration that disables multicast.
Focused verification
Enable multicast in a controlled test or use a unicast publication of the same content. If unicast works, keep the issue at multicast capability/policy rather than codec or file parsing.
