This corrects/normalizes license headers in misc. files, such as
config files, docs, build tools, tests, and externs. This does not
affect the compiled output, and is only done for consistency.
Issue #2638
Change-Id: I9d8da2de55243b08d7df2b743aac73c6f15e858a
In player, SimpleTextDisplayer was set as the default TextDisplayer. In
our UI, it changes the configuration to use the UITextDisplayer, and
UITextDisplayer gets constructed with the player. Later in our demo, it
resets the config, so an extra SimpleTextDisplayer gets constructed.
This introduces an extra TextTrack created by SimpleTextDisplayer.
This change sets the UITextDisplayer as the default TextDisplayer in
player's default config.
Closes#2516
Change-Id: I3f653be9fad8b2edbc2fb9de84e8abb327dcfc51
When the non-UI TextDisplayer is constructed, it creates an extra
TextTrack that can never be removed. This leads to a bogus text track
showing up in the UI when content is played in src= mode.
This changes the TextDisplayer to disable the extra TextTrack (since
there is no API to remove it) and changes the Player to ignore
disabled TextTracks when generating a track list for src= playbacks.

A regex in the TTML parser was looking for "word" characters (\w),
which is short-hand for non-whitespace ASCII characters, and excludes
Unicode characters and symbols from non-English languages.
There is a better option in Regex in some browsers, which is /\p{L}/u.
This is not supported universally yet, and defining an equivalent
regex constant using character codes is over 4kB of extra code.
It seems that the original author of that code meant "word" (\w) in
the sense of "non-whitespace" (\S), so we can just use \S instead.
This change also adds a regression test that doesn't depend on the
specifics of the regular expression used.

This changes the eslint rule to enforce a strict pattern for the
argument comments. The comment must appear before the argument and
must be /* foo= */. This still ignores line comments.

This method should probably never have been in the library, since it
creates a fixed-sized, muted element.

This reflects changes in Google's policy on JavaScript license
headers, which should be smaller to avoid increasing the size of the

This also updates the company name from "Google, Inc" to "Google LLC".

Previously, if no XML was produced, or if it failed to have a <tt> element,
we assumed that parsing had failed. This caught some failures, but not
every possible failure; there are some partial failures that still return
valid XML. These sorts of errors are signaled by the output containing a
<parsererror> tag; this CL makes us also return an error in this case.
It also corrects the documentation for XML parsing errors, which was
incorrect; it seems that we had been confusing INVALID_XML and
DASH_INVALID_XML for documentation.

Something I noticed while working on issue #2157; their text tracks
contained percent values with decimals in them (for example "4.17%"),
which was something the percentage-parsing regex we were using did
not handle.

For VOD, the first segment of every Media Playlist in every Variant
Stream must start at the same media timestamp. Thus, we can get the
start time once and store the value, and all the streams can use the
value directly. For live, we assume for the same.
This change reduces calling getStartTime_() from 15 times to once for
Angel One, and also fixes the text segment timestamp issue.
Also removed associated methods that no longer needed.

When using DOMParser parseFromString with an empty string, it returns an errored XML document. The next part of the code is then executed and throws an unnecessary error.
This adds a special case for an empty string.
It turns out that, on some browsers, incomplete XML does not properly
parse. This means the parseFirstCue tests did not work on those platforms.
This modifies those tests on platforms that do not support partial XML;
when no support is detected, it instead tries to get the first cue
from a non-partial segment.
This also modifies the HLS parser to only load partial text segments if
the text parser supports it; otherwise, the hls parser will load full
captions in order to extract start times.

Issue #2037
Change-Id: I58112864a818baf155b365a65fba1c8a56eb9520
Previously, when the text engine tried to load the start time of
a segment, it would parse every cue in that segment, then check the
time of the first cue. This was judged to not be a significant
performance issue, as parsing cues is a fast operation. However, it
did have an unintended side-effect: in some situations, this method
was being passed partial segments; notably, the HLS parser would load
the first 2048kb of the stream's texts to extract timing data.
If the caption parsers tried to actually parse an incomplete caption,
they would error.
This gives the text parsers "parseFirstCue" methods, and uses those
methods when it only needs the first cue anyway.
Fixes#2037

This ensures that we get the expected types and that type coercion
doesn't convert between types. This also ensures we are consistent
in how we check for equality of primitives in tests.

Instead of checking each property separately, just use
jasmine.objectContaining. This also adds a utility for matching a
number that is close to an expected value. This is required when
matching objects with toEqual().

Creating them in beforeAll will usually cause test contamination, so
they should be created in beforeEach instead so they are reset for

With the new style rule, we cannot have two statements on the same line.
So we can no longer have an "if" on a single line and we cannot have
an arrow function with a body on the same line as when it is used.
This is mostly a manual change.

CSS style 'direction' supports only horizontal directions, (left to
right, right to left), and writing-mode supports horizontal top to
bottom, vertical left to right, vertical left to right.
Separating the field 'writingDirection' to two fields 'direction'
and 'writingMode', so that they're the same as the css style names.

In our tests we regularly have checks that repeatedly check if a
function/spy has been called once more. To check this we would check
the call and then reset the calls each time.
To abstract this out, this CL defines two custom jasmine matchers that
allow us to check if a function/spy has been called once more.
To validate the matchers, TextEngine tests were update to make use of
it.

This reverts commit c38d4dd8d3, which
actually broke text range calculations in v2.3.10, and v2.4.2-v2.4.4.
The original commit was meant to account for the period start, but
resulted in a double-accounting of presentationTimeOffset.
The start and ends times passed into TextEngine's appendBuffer were
period-relative, so timestampOffset had already been applied. To
avoid further confusion and to fix the original issue the reverted
commit tried to address, these have been changed to
presentation-relative timestamps. Now the period start and all
offsets have been accounted for before the metadata reaches
MediaSourceEngine and TextEngine.
The tests added in the bad commit have been modified to test for the
opposite: that we do not erroneously account for timestamp offset when
calculating the buffered ranges for text.

Previously, we would read each individual VTTC and VTTE box in the
MDAT and associate them with durations in the TRUN. This worked for a
lot of content, but if sampleSize is defined in the TRUN, a duration
might refer to multiple VTTC boxes.
This changes the VTT in mp4 reader to parse the MDAT based on the TRUN,
to account for such situations.
For the moment, this only accounts for a single MDAT, and assumes that
the MDAT contains nothing but vttc or vtte boxes, listed in order.
