            Bug ID: 23553
           Summary: Segment parser loop appears to discard Media Segment
                    header
           Product: HTML WG
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: minor
          Priority: P2
         Component: Media Source Extensions
          Assignee: adrianba@microsoft.com
          Reporter: watsonm@netflix.com

Section 3.5.1, step 6, if the input buffer does contain a complete media
segment (sub-step 2) but it does not contain a complete coded frame, then the
coded frame processing algorithm is not run and at sub-step 4 the media segment
bytes (containing the header) are removed.

A possible fix would be to jump after sub-step 3 to the 'Need more data' step
if the entire media segment is not in the input buffer. The media segment data
is then not discarded (and step 6 is not executed) until the entire segment is
received.

This also obviates the need for the NOTE about incremental parsers.
