Instead of storing uris for SegmentDataDB in SegmentDB, store the
actual key so that we don't need to convert back-and-forth so
often.
Issue #1047
Change-Id: I2f6d1bc1e58abd7a210097dea757d1e2fc9d4cac
Before, stored content always needed an offline uri. As the id
will soon not be available before saving to storage, stored
content needed a way to represent content that was being
downloaded.
This change allows the offline uri to be null to represent content
that is being downloaded. It also allowed stored content to be
created from a Manifest (for content to be downloaded) and to be
created from a ManfiestDB (for content already downloaded).

Before we added variants, there was no variant ids field on
StreamDB. To support legacy downloads, we created variants
for streams with no variantIds.
This change moves that conversion into DBEngine so that outside
DBEngine, streams will always have variantIds.

To make it easier (and more consistent) to mock the default storage
engine in our tests, this change introduces StorageEngineFactory and
MockStorageEngineFactory.
StorageEngineFactory is now used to create instances of IStorageEngine
in the library. MockStorageEngineFactory makes it easy to override
specific parts of StorageEngineFactory.

Before if a stream was used on multiple variants, it would be created
multiple times. This change ensures that each stream is only created
once.
This change also makes use of standard array functions rather than
manual indexing with the goal to be easier to understand.

Since getStoredContent created a StoredContent from a ManifestDB
instance, createStoredContent better described the action of the
method.

Added tests for how we recreate variants from StreamDB instances.
This change does make createVariants public, but as it does not use any
internal state, there should be no reason to hide it especially as it allows
us to test it directly.
This change renames createVariants to recreateVariants to better represent
what it is doing.

Moved all the logic that is used to construct and parse uris for
manifests and segments into the offline scheme file.

This reverts commit 478fb1a473
("Detect and attempt to correct timeline sync issues") and commit
4334b6ea90 ("Add mediaSegmentReferences
to shakaExtern.Stream").
Timeline correction only addresses one class of broken live content,
while actually making it more difficult to diagnose other classes of
broken live content.
Issue #933
Change-Id: Ie71b8a45600ed0994626f53268fb90e336c3c62b
This will allow us, in many cases, to detect time sync issues in
content by comparing the media segment references to the presentation
timeline. If the references are outside the timeline, it may indicate
a common form of bad content, and we may be able to attempt to correct
it.
In some cases, the references are not available upfront. We can't
detect time sync issues in DASH with SegmentTemplate+duration, because
the references are not explicitly described by the manifest. We can't
detect time sync issues in DASH with SegmentBase, because the segment
index requires additional fetching and parsing. (SegmentBase is not
used with live content, so this should be a non-issue.)
This only introduces the new data, but does not use it for detection
or correction yet.

Adding the count of channels, as a new field for tracks and streams.
Used for HLS audio tracks.
Resolves#826.
Change-Id: I1448b4a8cfaf6dd798670bb2f0f3981d6c7e40c3
This change is to expose an audio track's role in order to differentiate
among a main / caption / commentary track that shares the same
language.
Issue #767.

This adds a method on Player to get the license expiration times for
the current EME sessions. This also adds the expiration times to the
stored content structure for offline content. This will update the
stored expiration while playing content (e.g. license duration changes
when playback starts).
Closes#727

Rather than having it in the DashParser as a network response filter,
we should have it in StreamingEngine. This will give it access to the
segment times so we can calculate the presentation times for the event.
Otherwise, there is no way to know when the event should actually occur
since the app can't know which segment is being downloaded or which it
came from.
This also adds startTime and endTime fields to the event so the app
doesn't have to calculate them. For reverse compatibility, the old
fields will still exist.

To better support alternate storage mechanisms, this change abstracts
shaka.offline.DBEngine into an interface called
shaka.offline.IStorageEngine.
DBEngine has been changed to implement this interface, and allows the
addition of implementations that do not use IndexedDB.

Add UI options to select current audio and text language.
Split selectTrack() into selectText() and selectVariant().
Stop automatically disabling ABR manager when a variant is selected.
Add a warning if selectVariant() is called while abr is enabled.

Parses DASH trick mode tracks and puts the extra trick mode Stream
into the manifest. StreamingEngine can now use this info to optimize
streaming during trick play mode.
Includes:
- a new demo asset with a trick mode track
- updates to tests (we now require at least one audio or video stream
and we require bandwidth attributes on them)
- updates to the parser's trickmode test
- a new StreamingEngine test

If a key status is 'output-restricted', treat the key as unusable.
In many cases it is, and we have no way of differentiating when it is
or is not. So our treatment of this status should be conservative,
and we should treat the key as unusable. This will prevent
HDCP-related failures that may be caused by adapting to a stream whose
output restrictions may not be met. The hasOutputRestrictions flag on
streams and tracks is now gone.
The caveat to this change is that if content is encoded with the same
key for SD and HD, and HD streams have HDCP restrictions that cannot
be met, we will now consider both the SD and HD streams to be
unplayable, even though we could still play the SD streams. Because
we can't separate the status of the two streams, we don't know for
sure if the SD streams can be played.
We will no longer support such content due to the complexity of doing
so, and due to the risk of playback failures on adaptation to
restricted streams. Streams with different security requirements
should always be encrypted with different keys. Content which does
not follow this best practice will no longer be playable in Shaka
without modifying the player.

Added new offline_utils.js to hold utility methods for offline
support. This also removes a circular dependency between
Storage and DownloadManager.
