>> Lets say the offer in step 1 included a hardware codec for video, the question of relevance for browsers is if in step 5 the SDP did not use that hardware codec, are the resources freed so another tab or application could use the hardware codec. In step 8, if that SDP used the hardware codec, that would fail if they were freed in step 5 and used by something else.
