Clarifications
ID	Title	Status	TPAC	Notes
18933	Segment byte boundaries are not defined	ASSIGNED		Assigned to Mark to work with Steven on text updates.
18922	Add a parser free, codec agnostic example	RESOLVED NEEDSINFO		If Haakon provides the example then we can discuss adding.
18921	append(data) should accept any part of media segment	RESOLVED WONTFIX		The current goals of the API require that applications do have an accurate offset of all segments. Applications are likely to compose presentations from multiple sources and need to understand how to map these together.
18920	addSourceBuffer parameter type should be optional	RESOLVED WONTFIX		Discussed previously during the call. Current consensus is to leave the type parameter to allow user agents to fail fast if they choose.
18642	Handle timestamp overflow in append(data)	ASSIGNED		Assigned to Aaron. Next action is to reorganise the append() algorithm to make it more precise.
18615	Define how SourceBuffer.buffered maps to HTMLMediaElement.buffered	ASSIGNED		Assigned to Aaron to work with Philip to remove any ambiguity.
18592	How much is "enough data to ensure uninterrupted playback"	NEW	YES	This topic requires more review and discussion to better align the content model for MSE with HTML5.
18575	Section 2. Source Buffer Model should be non-normative	ASSIGNED	YES	This is a LARGE change to the structure of the document to more clearly separate normative and informative language. Assigned to Aaron.
18601	Contradictory requirements for initialization segments	ASSIGNED	YES	Discussed previously during the call. Current proposal is to remove the text making initialization segments optional.
18587	Define clearly what data is removed when setting an explicit duration	ASSIGNED		Resolution of this bug is dependent on the SourceBuffer.remove modification in bug 18709.
18400	Define and document timestamp heuristics	ASSIGNED		Next step: reorganize append() description into sub-algorithms in order to introduce this proposal. This reorganisation work is captured in bug 18462.
18960	Define how AudioTrack.id & VideoTrack.id are generated	NEW	YES	This topic needs more discussion to conclude how to handle track IDs. Feedback from the wider WG might be helpful to ensure alignment with HTML5 media elements.
19531	simplify MIME type capability detection	NEW	YES	We will clarify that supporting MSE a subset of the formats the media element supports is acceptable to allow staged implementation. We need a little more review and discussion about the exact mechanism/method.
New features
ID	Title	Status	TPAC	Notes
18963	Provide a mechanism for rate limiting appending	NEW	YES	We should discuss whether this is required for v1.
18962	Allow appending with XHR	NEW	YES	We discussed this on the call recently. Current proposal is void appendStream(Stream). We need to discuss whether the any new mechanisms are required to indicate progress/completion. Also need to resolve how Stream support will be added to W3C XHR with WebApps.
18709	Add SourceBuffer.remove() method	NEW	YES	We need to review to confirm consensus before making the change proposed in the bug.
17006	<track> Setting track language & kind when the information is in a manifest	ASSIGNED	YES	Assigned to Adrian to make a proposal before TPAC for discussion.
17002	Specify a mechanism to determine which SourceBuffer an AudioTrack,VideoTrack, or TextTrack belong to.	NEW	YES	Should be simple to address but we need to discuss once we resolve bug 18960.
17000	Define a capability detection mechanism	RESOLVED LATER		We should wait for more implementation experience to see if we really need a programmatic mechanism for determining capabilities. Resolved LATER. Bug 19531 covers the format support aspect.
17094	Define segment formats for MPEG2-TS	ASSIGNED	YES	This needs more review and discussion. We want to discuss at TPAC if there are enough people with domain knowledge. Goal is to get agreement on text by the end of TPAC that we can add into the spec as a starting point for refinement.
