Module a.sdp

SDP, aka Session Description Protocol, as described in RFC 2327.

Nicked from shtoom.

This is a quick example on how to parse an SDP and access various fields:

>>> s = '''v=0
... o=root 6194 6194 IN IP4 192.168.11.224
... s=pyaculab
... c=IN IP4 192.168.11.224
... t=0 0
... m=audio 8092 RTP/AVP 0 8 101
... a=rtpmap:0 PCMU/8000/1
... a=rtpmap:8 PCMA/8000/1
... a=rtpmap:101 telephone-event/8000
... '''

>>> sdp = SDP(s)
>>> sdp.getAddress('audio')
('192.168.11.224', 8092)
>>> sdp.getMediaDescription('audio').rtpmap   
{0: ('0 PCMU/8000/1', <AudioPTMarker PCMU(0)/8000/1 at b715918c>),
8: ('8 PCMA/8000/1', <AudioPTMarker PCMA(8)/8000/1 at b715926c>),
101: ('101 telephone-event/8000',
<PTMarker telephone-event(dynamic)/8000/None at b715954c>)}
