            Bug ID: 25995
           Summary: Coded Frame Processing algorithm leaves in place
                    overlapping samples
           Product: HTML WG
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Media Source Extensions

ยง15 part 2 of the Coded Frame Processing algorithm states:

"If highest presentation timestamp for track buffer is set and less than
presentation timestamp[,] Remove all coded frames from track buffer that have a
presentation timestamp greater than highest presentation timestamp and less
than or equal to frame end timestamp."

This results in overlapping samples being left in the track buffer.  See a
demonstration at <https://gist.github.com/jernoble/50752b97d73c76673e5e>.

I propose the text be changed to:

"If highest presentation timestamp for track buffer is set and less than
[ADD]or equal to[/ADD] presentation timestamp[,] Remove all coded frames from
track buffer that have a presentation timestamp greater than [ADD]or equal
to[ADD] highest presentation timestamp and less than [STRIKE]or equal
to[/STRIKE] frame end timestamp."
