I agree that the SDP parser should not be tied to the SIP stack. From the design doc., doesn't look like the SIP stack itself does any payload parsing, it just leaves it to the application. Just glancing at the design doc., we probably want to remove uses of sip_str_t and sip_ (if sip_str_t-like type is considered useful, one could consider defining something similar in a common header file).
I think Girish was/is considering having the SDP stuff separate from libsip.so.1. I suppose we could have a generic lib for parsing different payloads, as you suggest, and have SDP as one of them (I am not sure if there is already a lib suitable for this). -venu On Tue, 14 Aug 2007, Diego B wrote: > Hi; > why adding an SDP parser to a SIP stack ? > I think this package has to be independent of the SIP stack. > > The SIP stack user may need to get a raw byte array of the SIP message > pay-load and then > base on the Content-type try to parse the data. > > Remember that the body of a SIP message can be a multipart-mixed, so, it > will need more complex parsing. > > I think that there have to be a mime- utility to parse and get objects > of a body of a SIP message. > It is true that SDP is the most used payload when trying to use SIP to > create multimedia messages. > But then you have SIMPLE, NOTIFY, MESSAGE, INFO, with all kind of > payloads.
