These patches and IPR support in general will be revisited when we
have a better model for how this should work.

Instead of filling the URI templates when parsing the manifest,
wait until the request is made to fill it. This reduces the time
it takes to parse the manifest.
This was tested using a stream with a 24-hour timeShiftBufferDepth.
Using a Chromebook pixel running Chrome 51. The average manifest
parse time was about 1 second before, now it is about 200ms.

* Permit non-zero presentation start times for VOD: some
presentations have segments which start too far from 0 to
allow the video element to begin playback; now the player will
start VOD presentations from the start of the first segment.
However, segments of the 2nd, 3rd, 4th, etc., Period of a
multi-Period presentation must still start close to 0 (the
player will not jump any gaps in the presentation).
* Prohibit seeking to regions at the beginning of the segment
availability window if segment information is missing from
that region: sometimes live manifests do not contain all the
segments in the segment availability window; now the player
will prohibit seeking to these regions.
* Update definition of live in DashParser to match Player and
Playhead.
* Simplify PresentationTimeline's constructor by just using setter
functions.

This ensures that small gaps from the start of the Period or from the
end of the Period are not interpreted as missing SegmentReferences.

Using goog.asserts will work with the compiler. So rather than
simply casting a nullable value when passing to a method, we can use
an assert which will correct the type and print a log if it somehow
is null.
This is not the same goog.asserts found in closure library, this
simply calls console.assert, but it is not required to do anything
for the compiler help.

Before there were two style to indent comments after an annotation,
using 2 and 4 spaces. Now this only uses 2 spaces.

The use of strings as indexers in the DASH manifest parser would
not work when the library is compiled. This fixes it as well as
adding type-safety to those parts.

Sometimes the calculated $Time$ value is not an integer due to
floating-point rounding errors, but the $Time$ value filled into the
template must be an integer.

This also changes from using Node types to using Element types. This
is more correct since the code only deals with XML elements and not
with other Node types (e.g. text content nodes).

* Move redesign docs to docs/design/
* Put all build output (including closure deps) in dist/
* Restore doc-building scripts
* Fix small doc error in MPD utils

* For SegmentTemplate with @duration, treat @startNumber as the number
of segments absent from the start of the Period.
* For SegmentList, fix off-by-one error when computing segment start times.
* Add more @startNumber documentation and unit tests.
Issue #192
Change-Id: I0b7950cc6cda0a2cbd345e13bd769a50f83d4982
* Updates all Copyright years to 2015.
* Adds licenses annotations to all JS.
* Makes all licenses identical to avoid repeated appearance in the
compiled output.
* Drops fileoverview annotations, which do not affect docs output.
* The linter still requires fileoverview on externs.
This patch required a newer closure compiler, since the previous
version we used had a bug regarding license annotations that caused
the license comment block to appear in the output once per file
regardless of uniqueness.

This reverts commit 8cb24652cb, due to
the fact that the new annotations caused our binary size to jump
by 52%.
The compiler preserves all 'unique' licenses, which causes trouble
since the comment blocks with the license annotations are not unique
and contain file overview comments as well.
We can re-examine this once we have restructured the license headers.

Can now specify negative values for the r attribute in SegmentTimeline.
Not supported with live when used on the last element.

This allows the app to intercept media requests to modify its URLs.
The callback accepts the URL for the request and returns a modified
URL or null to use the original.
Closes#148
Change-Id: I08352754ace05f318706fd93910097c0fa7696f0
Added a new class called FailoverUri which handles multiple URLs and
switches to others when one fails. This is also handles the request
itself. This replaces SegmentMetadata as well as a number of manual
requests.
The MPD parser now produces arrays of URIs rather than just one. The
MPD Processor then converts it to a FailoverUri inside the manifest.
Added unit tests to test the new functionality and updated the old ones
to the new changes.
This does not support failover on subtitles since subtitles are handled
by the browser.
Closes#68

A SegmentTimeline can appear inside a SegmentList and describes the
duration of the items in the list. A SegmentTimeline can also be
inherited from the Period or AdaptationSet. These have all been
added. Also added SegmentList support for dynamic MPDs.

Reflect modifications made in ISO/IEC 23009-1:2014/Cor 1:2015:
allow @startNumber to be 0 and compute the $Time$ placeholder using
the segment number relative to the start of the Period.
Closes#10
Change-Id: I4a9b0e4e3593c01e2e8d42a74572e78b9fba50d9
* Allow segments from different streams (Representations) to coexist
in buffer.
* Only fetch a single segment at a time.
* Remove id field from SegmentReference and remove SegmentRange.
* Only start the Streams once the buffer is "full".
* Stop DashVideoSource from triggering an extra resync during startup.
* Make Task.abort call order deterministic.
A follow-up patch is required to handle certain seek patterns in
live streams.
Issue #51
Change-Id: Ib7c9021471f1ed89323f19764463202b119cb491
This patch reworks SegmentIndexes so that any SegmentReference they
contain is guaranteed to be available. This makes SegmentIndexes work
consistently between static content and live content (specifically
content specified using SegmentTemplate with @duration).
* Rework StreamInfo to use a ISegmentIndexSource and a ISegmentInitSource,
which construct a SegmentIndex and an intiailization segment
respectively.
* Make ManifestInfo destructible and various async operations in
StreamVideoSource safer.
* Introduce LiveSegmentIndex, which manages SegmentReference eviction.
* Introduce DynamicLiveSegmentIndex, which manages SegmentReference
eviction and generation.
* Implement improved segment availability logic for segment eviction.
* Move SegmentIndex construction from MpdProcessor to several
ISegmentIndexSource implementations.
* Use a SegmentIndex to represent subtitles to simplify Stream creation
in StreamVideoSource.
* Move manifest update code from StreamVideoSource to ManifestUpdater.
* Move PeriodInfo.duration determination in MpdProcessor to StreamVideoSource.
* Since "forced" manifest updates are no longer required for content
specified using SegmentTemplate with @duration, simplify manifest update
code in DashVideoSource.
* Make Stream continue to update even if it runs out of
SegmentReferences, this simplifies previous resync logic and makes
DynamicLiveSegmentIndex work seamlessly.
* Refactor SegmentIndex and initialization fetch code in ContentDatabase.
* Download all SegmentIndexes in the background after the initial streams
have started.
Follow up work is required to remove seek range logic from
DashVideoSource.
