 ==2013 Q4 proposed==
+===Adaptive streaming for MP4 and SourceBuffer restarting===
+Reseting a SourceBuffer at the end of a logical stream requires information that is not available without a container parser. Being able to play multiple streams could be worked around by appending to a new SourceBuffer instead. In order to support fMP4 on some platforms (e.g. Windows 7, Vista) we also need a container parser.
+Tasks:
+* Extend nestegg parser for webm to support sourcebuffer reset
+* Container parser with fragmented mp4 support – Chris Pearce
 ===Memory management===
 Requesting of content through the JavaScript application is required for supporting both seeking and re-requesting of discarded time ranges. Discarding unneeded compressed data is needed to avoid wasting vast amounts of memory.

 * Requesting data through JavaScript API [MediaSource.readyState SourceBuffer.buffered]
 * Discarding of used coded frames [SourceBuffer.buffered]
-===Ad insertion (dynamic triggering approach)===
-Timeline management is needed for sequencing adverts using the dynamic triggering approach.
-Tasks:
-* Support segments mode [SourceBuffer.mode = AppendMode.segments]
-* Timeline management [SourceBuffer.buffered]
