Some examples of SDP |
||
SDP samplesBelow are some SDP examples you can reuse when working with RTP components. First sample is a simple uLaw 8000/mono stream: v=0 m=audio 5004 RTP/AVP 0 a=rtpmap:0 PCMU/8000/1 Since this is not a dynamic payload, receiver will not need additional SDP configuration. ALaw 8000/mono stream: v=0 m=audio 5004 RTP/AVP 8 a=rtpmap:8 PCMA/8000/1 Another non-dynamic payload, a MP3 streaming at 44100/stereo: v=0 m=audio 0 RTP/AVP 14 a=rtpmap:14 mpa/44100/2 First dynamic payload sample is a simple PCM (uncompressed) 8000/16bits mono stream: v=0 m=audio 0 RTP/AVP 98 a=rtpmap:98 L16/8000/1 Note, that this SDP setup must be applied on both transmitter and receiver, since dynamic payloads are not pre-defined in RFC. Now we specify a Speex streaming at 16000 Hz: v=0 m=audio 0 RTP/AVP 97 a=rtpmap:97 speex/16000 a=fmtp:97 mode="10,any" SDP - RFC 4566 RTP profile - RFC 3551 |
