# AWS::MediaConnect::FlowOutput
<a name="aws-resource-mediaconnect-flowoutput"></a>

The `AWS::MediaConnect::FlowOutput` resource defines the destination address, protocol, and port that AWS Elemental MediaConnect sends the ingested video to. Each flow can have up to 50 outputs. An output can have the same protocol or a different protocol from the source. The following protocols are supported: RIST, RTP, RTP-FEC, SRT-listener, SRT-caller, Zixi pull, and Zixi push. CDI and ST 2110 JPEG XS protocols are not currently supported by AWS CloudFormation.
