// SimulcastDescription can be serialized and deserialized by this class.

|
|
// Usage:
|
|
// Consider the SDP attribute for simulcast a=simulcast:<configuration>.
|
|
// The SDP serializtion code (webrtc_sdp.h) should use `SdpSerializer` to
|
|
// serialize and deserialize the <configuration> section.
|
|
// This class will allow testing the serialization of components without
|
|
// having to serialize the entire SDP while hiding implementation details
|
|
// from callers of sdp serialization (webrtc_sdp.h).
