[reSIProcate] How to decode SDP content?

[Scott Godin]

ParseBuffer is a generic parsing tool.  You will need to locate the
appropriate RFC or draft to know how to decode these values.  

 

Note:   There are some functions in Data.hxx that can be used to convert
to/from base64 and others.

Thank Scott,

I have looked at the files ParseBuffer and testParseBuffer, but I cannot
find any information about how to decode the profile-level-id and
sprop-parameter-sets in SDP content for Video codec H264.

a=fmtp:97 profile-level-id=421e00; packetization-mode=1;
sprop-parameter-sets=Z0LgHtoC0P5A,aM4zyA==

DBQ.

Hi all,

I have some SDP file for streaming that contains some encoded information.
I'm trying to decode the SDP content. Do you know what kind of method was
used to encode the information in profile-level-id and sprop-parameter-sets

v=0
o=- 571622436 4192730712 IN IP4 192.168.0.189
s=XXX
i=RTP Streaming
u=XXX
e=XXXX
c=IN IP4 192.168.0.138/64
m=video 8000 RTP/AVP 97
a=rtpmap:97 H264/90000
a=control:trackID=1
a=fmtp:97 profile-level-id=421e00; packetization-mode=1;
sprop-parameter-sets=Z0LgHtoC0P5A,aM4zyA==
m=audio 6666 RTP/AVP 96
a=rtpmap:96 mpeg4-generic/48000/2
a=control:trackID=2
a=fmtp:96 streamtype=5; profile-level-id=255; mode=AAC-hbr; config=1190;
objectType=64; sizeLength=13; indexLength=3; indexDeltaLength=3



Thanks in advanced,
DBQ.
