DCCP

DCCP	VLC uses this protocol (or access module) to read data from a device or network. This protocol is handled by the rtp module.

Datagram Congestion Control Protocol or DCCP is a protocol defined by RFC 4340. It is a proposed standard dated March 2006 for managing large volumes of data (such as streaming media).
It is useful with UDP, which lacks congestion control.
