## Features

- [x] SDP Encoder/Decoder

## Installation

```sh
go get github.com/pixelbender/go-sdp/sdp
```

## SDP Decoding

```go
package main

import (
	"github.com/pixelbender/go-sdp/sdp"
	"fmt"
)

func main() {
	sess, err := sdp.ParseString(`v=0
o=alice 2890844526 2890844526 IN IP4 alice.example.org
s=Example
c=IN IP4 127.0.0.1
t=0 0
a=sendrecv
m=audio 10000 RTP/AVP 0 8
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000`)

	if err != nil {
		fmt.Println(err)
	} else {
		fmt.Println(sess.Media[0].Format[0].Name) // prints PCMU
	}
}
```

## SDP Encoding

```go
package main

import (
	"github.com/pixelbender/go-sdp/sdp"
	"fmt"
)

func main() {
	sess := &sdp.Session{
    		Origin: &sdp.Origin{
    			Username:       "alice",
    			Address:        "alice.example.org",
    			SessionID:      2890844526,
    			SessionVersion: 2890844526,
    		},
    		Name:       "Example",
    		Connection: &sdp.Connection{
    			Address: "127.0.0.1",
            },
    		Media: []*sdp.Media{
    			{
    				Type:  "audio",
    				Port:  10000,
    				Proto: "RTP/AVP",
    				Formats: []*sdp.Format{
    					{Payload: 0, Name: "PCMU", ClockRate: 8000},
    					{Payload: 8, Name: "PCMA", ClockRate: 8000},
    				},
    			},
    		},
    		Mode: sdp.ModeSendRecv,
    	}
    	
	fmt.Println(sess.String())
}
```
