WebRTC Session Descriptor Parser and Builder

Build a session descriptor parser and builder utility that processes WebRTC session descriptions for a media streaming application. The utility should handle parsing existing session descriptions and creating new ones with proper formatting.

Capabilities

Parse Session Descriptions

  • Given an SDP string containing audio and video media sections, parse it and return a dictionary with 'type' and 'sdp' keys @test
  • Given an SDP string with VP8 video codec, extract the codec name and payload type from the video media section @test
  • Given an SDP string with ICE candidates in the media sections, extract all candidate strings @test

Build Session Descriptions

  • Create a new offer-type session description with audio and video media sections @test
  • Parse an existing SDP string, add a new ICE candidate to the first media section, and output the modified SDP string @test
