Christer,

Thanks for the feedback - you are correct about the missing semicolon. We'll fix it in the next version.

Thanks,

Hi,

I guess (hopefully) this is simply an editorial issue, and has nothing to do with the actual scenarios:

In SDP examples where you use the fmtp attribute to describe codec properties, you don't use semicolon between the specific properties.


Example from page 13:


m=audio 49170 RTP/AVP 97
a=rtpmap:97 MPA
a=fmtp: 97 layer=3 bitrate=10

Shouldn't it be:


a=fmtp: 97 layer=3;bitrate=10



Now, I admit I don't know how MPA has defined the use of the fmtp attribute, but other codes using the fmtp attribute do use semicolon between the properties, so...



An example for MPEG-4 (RFC3016, page 15).


m=video 49170/2 RTP/AVP 98
a=rtpmap:98 MP4V-ES/90000
a=fmtp:98 profile-level-id=1;config=000001B001000001B5090000010000000120008440FA282C2090A21F
