             imported/w3c/web-platform-tests/media-source/mediasource-sourcebuffer-mode.html

The newest revision of the web-platform-test suite for Media Source tests new behavior
added to the MSE specification. Specifically, setting a MediaSource's duration will no
longer implicitly truncate the source's active SourceBuffer objects.

* Modules/mediasource/MediaSource.cpp:
(WebCore::MediaSource::setDuration): Return exception if issued by setDurationInternal.
(WebCore::MediaSource::setDurationInternal): Bring "duration change" algorithm up to spec.
* Modules/mediasource/MediaSource.h:
* Modules/mediasource/SampleMap.h:
(WebCore::PresentationOrderSampleMap::begin): Add const accessor.
(WebCore::PresentationOrderSampleMap::end): Ditto.
(WebCore::PresentationOrderSampleMap::rbegin): Ditto.
(WebCore::PresentationOrderSampleMap::rend): DItto.
(WebCore::DecodeOrderSampleMap::begin): Ditto.
(WebCore::DecodeOrderSampleMap::end): Ditto.
(WebCore::DecodeOrderSampleMap::rbegin): Ditto.
(WebCore::DecodeOrderSampleMap::rend): Ditto.
* Modules/mediasource/SourceBuffer.cpp:
(WebCore::SourceBuffer::highestPresentationTimestamp): Added convenience method.
(WebCore::SourceBuffer::removeCodedFrames): Drive-by fix; use .values() rather than
    pulling the value out of each HashMap iterator.
