JAHConvertSDP

What is this?

This is an Objective-C version of SDP-Jingle-JSON. Check out that project for more details.

How to use it

// I have SDP, but want Cocoa objects:
NSDictionary* objects = [JAHConvertSDP dictionaryForSDP:sdp withCreatorRole:@"initiator"]; // or @"responder"

// I have a Cocoa object (a dictionary of session and content descriptions), but want SDP:
NSString* sdp = [JAHConvertSDP SDPForSession:objects sid:nil time:nil];

Jingle Objects

The format for the generated dictionary content is:
