This is an automated change to convert use of "function" functions
to arrow functions. This doesn't change all uses of bind() that
could be converted. This also doesn't remove all "function" functions.

By listening to events on document in the capturing phase, we can
avoid complex event shims on HTMLVideoElement. By monitoring
global PiP state on the document, we can get rid of the getter and
setter for the document's PiP element, as well.

Safari on iOS does not support HTML5 fullscreen API. There
seems to be a (separate) way for a video element to enter
fullscreen mode. I will see if we can adopt it in a different CL.
For now, just hide the button if fullscreen API is not supported.

The unprefixed EME launched with macOS 10.14 (Mojave) rejects requests
for the key system IDs we know how to use. So until the bug we filed
against Apple is resolved, prefer the prefixed API.

This adds a polyfill for Apple's prefixed EME implementation. This
will be used on all macOS versions prior to 10.14 (Mojave) and on
Safari versions prior to 12.1.
This also adds support for FairPlay license protocol eccentricities
in DrmEngine, so that the proper formatting is used for requests and
responses.

Instead of triggering src= based on 'video/mp4' MIME types, ask the
browser what it can support using video.canPlayType().
Querying canPlayType() also allows us to detect src= support for
native HLS in Safari.
The original version of this change also added a complete fallback
system to detect MIME types based on common file extensions and
fetch MIME types via HEAD request when necessary, but the load graph
system does not yet allow us to make async decisions about destination
node. So this async MIME detection is commented out for now.
Closes#816 (src= single file playback)

This CL creates the "loaded with src=" node and its initial
implementation. Adding this node required some changed to the routing
logic as a new destination was created.
We will use src= when given mp4 content or media source is unavailable.
We detect mp4 content via the mimeType in |load| and/or the file
extension. When media source is not available on a platform, we fall
back to using src=. To do this, we check if media source is available
whenever |load| is called, and will route to the src= branch if media
source is not found.
To avoid pre-initializing media source (when it is not available) we
modify the |initializeMediaSource| flag in |attach| and |unload| when
media source is not available.
Doing this showed that we had inconsistent behaviour between |attach|
and |unload|. |attach| would default to initializing media source
whereas |unload| would not. This has been fixed.

- Fix the link to Dolby's Dolby Vision Profiles and levels PDF
- Was pointing to a document version that no longer exists
- Update Dolby Vision regex to match all DV codecs
- Dolby Vision is available in 4 different (base) codecs: dvhe, dvh1, dvav, dva1
- dvh* represents HEVC-based Dolby Vision
- dva* represents AVC-based Dolby Vision.
- Do not remove Dolby Vision codecs on Chromecast
No need to remove Dolby Vision codecs on Chromecast. Chromecast's canDisplayType will reject them when the cast receiver or the attached display can't play Dolby Vision.
On Dolby Vision capable cast receivers attached to a TV in Dolby Vision mode, canDisplayType does not reject Dolby Vision streams. One such device is the Chromecast Ultra. With this change, Shaka Player plays Dolby Vision on qualifying setups.
This CL limits the use of |setTimeout| by wrapping it in our own timer
class. The timer class makes it easier to track and cancel time-based
events.
To ensure that|setTimeout| is not used outside of our timer classes, the
conformance rules have been updated to only allow |setTimeout| to be
used by our timer classes.
Since |setTimeout| is very similar to |setInterval|, the conformance
rules for |setInternal| rules were updates to reflect more of the logic
behind why we don't want to use |setTimeout| and |setInterval| directly.

Tizen Smart TVs do not play opus content well when using MSE. To prevent
Shaka Player from trying to play opus content on Tizen, we override
media source's isTypeSupported to reject opus content.
Since most content will have AAC as a fallback, this should not limit
playback on Tizen.

number of comments and JSDoc descriptions, and does some
formatting standardization.
This doesn't fix every single issue, but it fixes a lot. Notably,
there were some formatting issues I declined to standardize due to
ambivalence on what the proper standardization would be; for example,
when and where empty lines should show up in JSDoc.

Now each EME polyfill can be removed independently; this allows
someone to remove just the IE11 polyfill while still keeping the
others.
This adds a priority ordering to the polyfills so the nop polyfill
will be run last as a fallback if there are no other polyfills.

A bug in our Promise polyfill caused issues with the recently-added
AbortableOperation class on IE11. Since external polyfills for this
are smaller, it is easier to remove ours in favor of a third-party
polyfill. Applications that wish to support IE11 must now load this
additional polyfill.
We are using the "es6-promise-polyfill" module from npm, but any
compliant polyfill should suffice.
One feature our own polyfill offered was the ability to flush all
Promises, which allowed us to write synchronous unit tests that
simulated async processes. To get this ability back, we are now
using the "promise-mock" module in our tests.
Getting "promise-mock" to load correctly involved switching from
"requirejs" to "cajon", which builds on requirejs and supports
AMD modules more directly.

This digests and organizes many of the automatic settings in eslint,
and changes several of them to be more strict. This also fixes the
following errors:
- array-callback-return
- no-catch-shadow
- no-multi-spaces
- no-new
- no-throw-literal
- no-useless-call
- no-useless-concat
- no-useless-return
Several checks have been organized into a group of checks we should
use, but need more time to implement and fix. Some other checks have
been delegated to the Closure compiler, which can more precisely
whitelist exceptions.

The eslint configuration is derived from analyzing the style of our
sources as they are now, plus a few tweaks.
In particular, we have disabled checks for undefined variables and use
of console, both of which the compiler handle with greater precision.
The compiler already knows what is defined in the environment through
our externs, and has specific exceptions for the use of console (demo,
tests).
We have also disabled a few checks that we should use, but will
require many changes to the code: no-unused-vars, no-redeclare,
and comma-dangle.
This commit also fixes several types of eslint errors that were easy:
- no-useless-escape (unneccessary escape characters in Regexp)
- no-constant-condition (using true/false/0/1/etc in if/while)
- no-fallthrough (caught an actual bug in one EME polyfill)
- no-irregular-whitespace (we had a UTF-8 nbsp in externs)
- no-cond-assign (using an assignment inside a conditional)
To satisfy stricter provide/require checks in the Closure Compiler
Linter, we will no longer use provide/require at all in tests. We
will still use provide in test utilities (test/test/util/) since it
sets up the namespace for us. But we will not use require there
because there is no deps management for test code.

SourceBuffer.remove, when told to remove exactly up to a keyframe,
will also remove that keyframe and all of the content till the next

The HTML5 'input' event does not work correctly on all input elements

Two EME polyfills currently assume persistent storage support: one
for old Tizen TVs and other older embedded Chromium devices, and one

This backfires when an application is trying to detect support for

By removing this assumption, we do not convey support for EME features
that are not known to be available on these devices.

This is part of adding a new conformance rule to add additional type
safety. This will disallow using properties of unknown types or using
unknown properties.
The first parts will be fixing errors caused by the new rule. These
are backwards compatible, so can be applied before the rule is enabled.
Once all the errors and bugs are fixed, the rule will be enabled.

configurable, otherwise it cannot be set twice. Somehow the resulting

The Chromecast reports supporting IndexedDB but whenever an insert
command was performed, the operation would hang indefinitely.
This change introduces a pollyfill for the Chromecast that will
remove the indexed db reference which will have DBEngine's
"is supported" behavior to report no support.
Alone this change would not stop the tests from running, so the
DBEngine tests had to be updated to first check that the DEngine
is supported on the active platform.
