#![warn(rust_2018_idioms)] #![allow(dead_code)] //! Package rtcp implements encoding and decoding of RTCP packets according to RFCs 3550 and 5506. //! //! RTCP is a sister protocol of the Real-time Transport Protocol (RTP). Its basic functionality //! and packet structure is defined in RFC 3550. RTCP provides out-of-band statistics and control //! information for an RTP session. It partners with RTP in the delivery and packaging of multimedia data, //! but does not transport any media data itself. //! //! The primary function of RTCP is to provide feedback on the quality of service (QoS) //! in media distribution by periodically sending statistics information such as transmitted octet //! and packet counts, packet loss, packet delay variation, and round-trip delay time to participants //! in a streaming multimedia session. An application may use this information to control quality of //! service parameters, perhaps by limiting flow, or using a different codec. //! //! Decoding RTCP packets: //!```nobuild //! let pkt = rtcp::unmarshal(&rtcp_data).unwrap(); //! //! if let Some(e) = pkt //! .as_any() //! .downcast_ref::() //! { //! //! } //! else if let Some(e) = packet //! .as_any() //! .downcast_ref::(){} //! .... //!``` //! //! Encoding RTCP packets: //!```nobuild //! let pkt = PictureLossIndication{ //! sender_ssrc: sender_ssrc, //! media_ssrc: media_ssrc //! }; //! //! let pli_data = pkt.marshal().unwrap(); //! // ... //!``` pub mod compound_packet; mod error; pub mod extended_report; pub mod goodbye; pub mod header; pub mod packet; pub mod payload_feedbacks; pub mod raw_packet; pub mod receiver_report; pub mod reception_report; pub mod sender_report; pub mod source_description; pub mod transport_feedbacks; mod util; pub use error::Error;
