Draft
This page is not complete.
The appendWindowEnd property of the
SourceBuffer interface controls the timestamp for the end of the append window, a
timestamp range that can be used to filter what media data is appended to the
SourceBuffer. Coded media frames with timestamps wthin this range will be
appended, whereas those outside the range will be filtered out.
The default value of appendWindowEnd is positive infinity.
Syntax
var myAppendWindowEnd = sourceBuffer.appendWindowEnd;
sourceBuffer.appendWindowEnd = 120.0;
Value
A double, indicating the end time of the append window, in seconds.
