This change only calls setters if we need to override the existing value
(or more specifically, set a value that's absent).

Instead of selecting the base URL initially or when a load error occurs, it is now selected when a chunk or initialization chunk is created. The selected base URL is then assigned to `RepresentationHolder.lastUsedBaseUrl` that is excluded in case of a load error. For a next chunk another base URL will be selected by using the `BaseUrlExclusionList`.

- Android 12 will not allow our download service to be
restarted from the background when conditions that
allow downloads to continue are met. As an interim
(and possibly permanent) solution, we'll keep the
service in the foreground if there are unfinished
downloads that would continue if conditions were met.
- Keeping the service in the foreground requires a
foreground notification. Hence we need to be able to
generate a meaningful notification for this state.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.
Notable renamings that might be controversial:
- `onPlaybackStateChanged(int state)` to `onPlaybackStateChanged(int playbackState)` affected a lot of lines but seems more consistent with other '-Changed' methods.
- `handleMessage(int messageType, Object payload)` to `handleMessage(int messageType, Object message)`
- `ExtractorInput` and `DataSource` inherit `DataReader` which had `read(byte[] target, ...`, while data sources normally called the first parameter `buffer`. I have standardized these all to use `buffer` even though it looks out of place in the `ExtractorInput` interface (which has more `read` methods with `target`).

A no-op change that changes the signature of the onChunkLoadError method of the ChunkSource. Implementors can get the exclusion duration directly from the LoadErrorHndlingPolicy instead of receiving it as an argument of the callback.

After this change, multiple BaseURL elements are parsed, but the player still only uses the first BaseURL element appearing in the manifest and its corresponding availabilityTimeOffsetUs.
PiperOrigin-RevId: 380775256
This change parses the entire BaseURL element including DVB extension attributes, stores it in an instance of new BaseUrl class and puts it in a list of base URLs of the resulting Representation. The base url handling itself is still the same, which means that only the first base url is taken into account, just as before this change.

Even when fixed to the US locale (and thus avoiding surprising behaviour
in e.g. Turkish locale with "i" and "I") there are unexpected behaviours
when upper and lower casing non-ASCII characters.
For example it's sometimes not symmetric, e.g.:
"ẞ".toLowerCase() -> "ß"
"ß".toUpperCase() -> "SS"
In all the ExoPlayer usages we are either dealing with known-ASCII
strings (e.g. MIME types) or comparing against ASCII constant strings
anyway, so it seems easier to just use Guava's ASCII-only class in these
cases.
This change also includes some null-twiddling, because
Util.toLowerInvariant() is null tolerant, while Ascii.toLowerCase() is
not. Most of the usages were already non-null, and it was easy enough to
change the remaining ones to be so by simple reordering of statements.
I'll make an equivalent change for Util.toUpperInvariant() next.

- SampleQueue.peek is replaced with SampleQueue.read with
FLAG_PEEK. This also exposes peek functionality through
SampleStream.
- Use of DecoderInputBuffer.isFlagsOnly is replaced with
FLAG_OMIT_SAMPLE_DATA. This flag can be used with or
without FLAG_PEEK, where-as previously the read position
would never be advanced for an isFlagsOnly buffer.
- formatRequired is replaced with FLAG_FORMAT_REQUIRED.

The available end time was accidentally substracted by the start time
of the last period.
To avoid similar time reference confusion in the future, also renaming
many variables and methods to clearly reflect the time reference point.
And to avoid constant conversion, the processManifest method also
attempts to converge to time relative to the start of the window as
quickly as possible.

`TrackSelection` had mutation methods which were to be called only
internally by ExoPlayer components but were exposed in the
public `Player` interface.
The mutation methods have been moved out of `TrackSelection`
to a new class `ExoTrackSelection`.
Current track related read-only method have also been moved out,
because they are actually something quite unclear.
Even for a single item playlist, it's the track being buffered rather
than the track being played, which is unclear.
But when you have a playlist it starts to get really confusing,
because if the next item is being buffered, then it's actually
the last track to be buffered in the currently playing item.
As a final aside, the implementations don't do proper thread synchronization
to ensure visibility of updated state by the calling thread.
Exposing those mutable methods in the public `Player` interface
was problematic because they leaking internal concepts of `ExoPlayer`.
This is also required to minimize the `Player` interface for long term
stability.
`ExoTrackSelection` is a subclass of `TrackSelection`.
This is not ideal as an `TrackSelection` implementation could
break the current immutability.
This was done in order for this refactor to be simpler.
A future patch will fully split the two classes.
All `MediaPeriod` and `Sources` had to be updated to use the new
`TrackSelection` dynamic aspect class name.
An alternative would have been to break ExoPlayer's public API, keeping
`TrackSelection` as the dynamic aspect name, and calling the public static
aspect class `TrackSelectionState` or similar.
Nevertheless, while it would have impacted less files, it would have
many more small apps and casual users of ExoPlayer.

In many cases we just used "playback speed" as a detailed Javadoc
parameter or return type definition. This doesn't define which scale
the speed is using.
PlaybackParameters as the main point to set the speed already uses a
more precise wording to describe the value as a factor by which playback
will be sped up.
This change replaces other usages of "playback speed" with this wording
whereever we would usually add a unit, keeping "playback speed" for
summary statements etc to reference the general concept that doesn't
usually require a unit.

In order to ensure we can update the values for new manifests but still use
the user provided override, we need to save the original and the updated MediaItem
seperately.
And in order to incorporate the existing logic for the min/max supported live
offset, which we already use to correct the target offset, also move both places
together so that all the adjustment happens in one place.
Logical adjustments to the previous min/max supported live offset:
- Use the user-provided MediaItem values if set
- Use the newly parsed ServiceDescription values if available.
- Limit the minimum to 0 if the current time is in the window and we can
assume to have low-latency stream.
- Add minBufferTime from the manifest to ensure we don't reduce the live
offset below this value.

PiperOrigin-RevId: 338235754
The available duration used a "live edge" that was calculated in
the previous iteration and was thus quite old. Also it also used
the end of the last available segment, but the actually available
duration for buffering needs to be clamped to the current live edge
for low-latency streams.

We stopped using using this MIME type in
74a9d8f680
This broke subtitle decoding in some cases (Issue: #7985), which I
fixed in
7b8895d655.
After some discussion we've decided SubtitleDecoderFactory shouldn't
depend on Format.containerMimeType (since the samples have already been
extracted by this point, so the container shouldn't matter). So this
change fixes DashManifestParser to use MimeTypes.APPLICATION_MP4VTT (and
reverts the no-longer-needed SubtitleDecoderFactory change).

TestExoPlayerBuilder can be used from both emulator and robolectric
tests, TestPlayerRunHelper uses Robolectric Looper behaviour, meaning
it can be moved to the robolectricutils module in a follow-up change.

This was broken by 74a9d8f680
because DashManifestParser switched to setting Format.sampleMimeType to
text/vtt while SubtitleDecoderFactory was still expecting
application/x-mp4-vtt. This change teaches SubtitleDecoderFactory to
check both Format.containerMimeType and Format.sampleMimeType.
I'll investigate a follow-up change to remove
MimeTypes.APPLICATION_MP4VTT completely (it's currently still used in
AtomParsers).
