The UDPv4 receiver module receives a stream using UDP version 4 across a network. It supports the static and dynamic variants of the BLP, EBLP and MCUF protocols.
      The configuration of the UDPv4 receiver module with name
      NAME is located in the udp4receivers/NAME
      subdirectory.
    
      The file outstream contains the name of the stream to
      write the received network stream to.
    
      The protocol to use is configured in the file protocol.
      It can contain the string blp, eblp or
      mcuf to select the BLP, EBLP or MCUF protocol respectively.
      If the file is not present, all protocols are accepted.
    
      The file bind contains the local address to bind to.
      It must contain the IP address and the port, i.e. a string
      <IP>:<port> (hostnames are not supported).
      If the local address should be determined automatically, the file
      can contain 0.0.0.0:0.
    
      The file source contains the source address
      as a string <IP>:<port>
      (hostnames are not supported).
      
      If the source address file exists, only a stream from the specified
      address is accepted.
      Otherwise, the stream can be sent from any address.
      
      If both the source address and the protocol are given, dynamic
      stream request packets are sent to the source address.
