Introduce `NativeTextDisplayer` as a replacement of
`SimpleTextDisplayer`. But keep them both work.
Is MSE mode, `NativeTextDisplayer` creates `<track>` elements for text
streams. And listens to change events on both ends to keep them in sync.
In SRC mode, `NativeTextDisplayer` would do nothing, the player uses
original TextTracks instead.
Advantages of `NativeTextDisplayer`:
- Allow text track selection using the browser built-in UI
- Allow text track manipulation using native APIs
- Avoid transferring and processing cues in SRC mode

Needed for #5022
This PR does not enable AirPlay on MSE yet, but moves shaka from using
`src` attribute to `source` tags. With this change we will be able to
enable it more easily, as `src` and `source` should not be used
together.
- Fix bogus assertion failure in tests on Safari (#6272)
- This test should not be seeking so close to the duration (10ms) as to
cause flakiness on certain browsers. Adjusting the seek time fixes the
assertion without compromising the purpose of the test.
- Fix uncaught rejections in load graph tests (#6274)
- These tests had calls that were interrupted by the teardown process
that occurs after the test body. Waiting for the operations before
ending the test fixes the issue.
- Fix interrupted load in test on Tizen (#6274)
- This test triggers a deliberate DRM error without waiting for load().
On most platforms in the lab, the load() operation completed before the
error. Not so on Tizen. This exposed a general problem in which we
should be catching errors in this test. Only timing saved us on most
platforms.
Closes#6272Closes#6274
The state engine mechanism, designed for the player class, was
over-engineered. The structure of the class makes debugging player
errors unnecessarily annoying, by obfuscating the code-path the error
followed, and in general
has created a significant amount of technical debt.
This changes the player to use an async-await setup for the top-level
operations, laying things out much more cleanly
and linearly.

Power-saving features on Chrome and Edge were subtly interfering with
playback tests. Timers could be throttled, and both video-only media and
media in occluded windows could be paused by the browser.
This was discovered only after awaiting play() Promises in all tests.
These Promises were being rejected with useful error messages that led
to these discoveries.
Awaiting play() requires us to disable stall detection during playback
tests. This is because on some platforms, stalls get resolved by calling
pause() and then play(), which would cause the original awaited play()
Promise to be rejected.
Finally, some Player tests created additional Player instances that were
unnecessary. Removing those allowed me to centralize most of the
configuration to disable stall detection.
The test to show that src= playbacks can log width/height data was
failing on Tizen. This is because Tizen was ignoring the SAR (sample
aspect ratio) and showing the content at 256 pixels wide, whereas
other platforms were displaying at 258 pixels wide. The point of the
test was never to check a platform's support for SAR, so the video has
been re-encoded to display consistently across platforms.
This issue began when the test was added in PR #4435.
The video file is now also much smaller than it was before (from 177kB
to 37kB).
Re-encoding was done with:
```sh
ffmpeg \
-i test/test/assets/small.mp4.orig \
-c:v h264 -vf setsar=1:1 -crf 51 \
-c:a aac -b:a 16k \
-y test/test/assets/small.mp4
```
addChaptersTrack() was already an async method, but it did not wait
for the chapter data to be loaded by the browser. The solution is to
wait for the `load` event on the `<track>` element we create.
To accomplish this, some cleanup and refactoring was done in how
tracks are managed. Summary of changes:
- The `addtrack` event, which triggered management of tracks in src=
playback, is now used for all types of playback. In src= mode, it
manages all tracks, and in MSE mode, it only manages chapters
tracks (which are added to the video element as in src= mode).
- `processChaptersTrack_()` has been renamed to
`activateChaptersTrack_()`, since its only job is to set the
track's mode field to make the browser load it.
- `activateChaptersTrack_()` is now only ever called via the
`addtrack` event.
- `activateChaptersTrack_()` no longer loops over all chapter tracks
on a timer, and instead only touches the single track it was
called for.
- `addSrcTrackElement_()` now returns the HTML `<track>` element it
creates.
- `addChaptersTrack()` now awaits a `load` or `error` event to
complete (or fail) the operation.
- Existing tests for addChaptersTrack had long delays to work around
this issue; these delays have simply been removed.
Fixes#4186
This change fixes tests on Chromecast by loading tests later in the process. Test scripts are now dynamically inserted by boot.js, rather than loaded by Karma. The bootstrapping code then awaits the completion of that before starting the Karma frameworks (Jasmine) to run the tests.
This also removes the use of goog.provide/goog.require in tests and test utils. We don't need to load test utils or library sources dynamically in each test, and this gives us more explicit control over script loading and ordering.
Closes#4094
This new method can make a HEAD request to the server to determine the MIME type. The old method (addTextTrack) is now deprecated and will be removed in v4.
Refactor the test util and relevant files for compiler upgrade.
In test files, a few files depending on each other formed a
dependency loop.
For example, test/Util has a few methods for waiting/delay that
uses Waiter, and those methods should be in Waiter.
This changes helps to break the dependency loop, and helps to
unblock the compiler upgrade.

One of the src= playback tests was failing on Chromecast with an
estimated rate of about 20% when the src= tests are run alone. The
timeout for playback to start was found to be too short on that
resource-limited embedded device. This increases the playback timeout
in the test.

Changes to the load() promise resolution on iOS for #2483 accidentally
broke language preferences in src= mode, and the regression test for
this revealed subtleties in how and when tracks may be selected with
Apple's native HLS.
By waiting for a "change" event on video.textTracks, we can make sure
Apple is ready to accept our own text track selection.
This should now work correctly on all platforms.

These issues were mostly introduced in "Don't preload data on iOS",
and were not detectable in Chrome. They came up during a full test
pass in our test lab on all browsers.

Instead of calling video.load() and waiting for loadeddata for src=,
wait for loadedmetadata. This should be a safe event to use in most
cases, and calling video.load() causes native HLS to start preloading
an uncontrollable amount of content.
The exception is if the app sets preload='none' on the video element.
If this happens, we will detect it, log a warning, and avoid the
loadedmetadata event which may never fire. This is not a scenario we
will officially support, but at least we can prevent a hang in
player.load().

When SimpleTextDisplayer is constructed, a TextTrack is created,
and that cannot be removed. This introduces an extra TextTrack when the
content is played in src= mode.
This is the straight-forward solution to filter the extra TextTrack out
by the label in src= mode.

We used to alias static utility methods by assigning the method itself
to a local variable. This is not allowed by the new Closure Compiler
release that we are adopting, and for good reason.
The old compiler did not understand the use of "this" in static
methods, but the new one does. And it turns out that when we start
using "this" in static methods (see #2532), aliasing the method itself
can break everything.
When you refer to "this" in a static method, it refers to the class.
This is really useful in utility classes that have private static
methods they use to perform common tasks. However, just as it ruins
the value of "this" to alias an instance method, the same is true of
an ES6 class's static method.
The fix is to always alias the class instead of the method. The new
compiler will simply not let us get away with the old way any more, so
regressions after this are unlikely.

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.

For some reason, on Edge and IE, starting this particular piece of
content at time 5 results in playback beginning at 4.9. It could be
that the number is rounded to a keyframe or something.
This changes the test to expect the start time to be within 200ms of
the requested start time.

This removes periods from the internal manifest structure and cleans
up code and tests accordingly. This leaves us unable to play
multi-period DASH & offline streams until the main period-flattening
algorithm is completed in shaka.util.Periods.
Three test cases have been disabled for the moment.
Multi-period playback will be restored in a smaller, more focused
follow-up commit, with disabled tests re-enabled.

The Player ratechange event is a filtered version of the video
ratechange event. This is necessary because we manipulate
playbackRate as part of our buffering state management.
The UI uses this Player ratechange event to drive the playback rate UI
menu, but the event was not firing for src= playbacks (native HLS or
plain MP4s).
This fixes the ratechange event for src= playbacks, and also fixes a
small mistake in the MediaSource setup that could have resulted in the
ratechange event being triggered before playRateController_ was
created.

This reorders the rules so they mostly are ordered the same as the
eslint documentation. The exception is the few at the top, most of
which should be removed. This also removes some rules that appear in
the recommended or the Google set. Lastly this adds some more rules:
- Require parenthesis when using "new".
- Disallow confusing regex (e.g. /=/).
- Disallow some confusing coercions (e.g. +foo).
- Disallow some Unicode characters in a regex.
- Disallow using "async" in a Promise constructor.
