Read SDP

var expected =

var value = SDPSerializer.ReadSDP(Encoding.UTF8.GetBytes(expected));

Write SDP:

var sdp = new SDP()
{
    Version = 1,
    Origin = new Origin()
    {
        UserName = "-",
        SessionId = 92389283923923,
        SessionVersion = 2,
        Nettype = "IN",
        AddrType = "IP4",
        UnicastAddress = "127.0.0.1"
    },
    SessionName = Encoding.UTF8.GetBytes("Live video session"),
    MediaDescriptions = new List<MediaDescription>()
    {
        new MediaDescription()
        {
            Media = "video",
            Port = "9",
            Proto = "UDP/TLS/RTP/SAVPF",
            Fmts = new List<string>(){ "96" , "97"}
        }
    }
};

byte[] serialized = SDPSerializer.WriteSDP(sdp);

Limitations:
