I have a few related comments on jsep-08: Section 4.1.1 defines the BUNDLE policy values. It certainly appears that when you are using the default "balanced" policy there will be *separate* bundle groups for audio and video, and that the SCTP m-line will not be bundled. However section 5.2.1 says: Once all m= sections have been generated, a session-level "a=group" attribute MUST be added as specified in [RFC5888]. This attribute MUST have semantics "BUNDLE", and MUST include the mid identifiers of each m= section. The effect of this is that the browser offers all m= sections as one BUNDLE group. However, whether the m= sections are bundle-only or not depends on the BUNDLE policy. This doesn't deal with bundle policy - this rule seems to apply only to max-compat policy. Section 7.1 says that both Alice and Bob are using the "balanced" policy, which should lead to separate bundles for audio and video, but the example shows a single bundle - consistent with a "max-bundle" policy. There are no examples that show more than one bundle group. Thanks, Paul
