- Use a single constant for unset/unknown times across
all time bases. Note also that this moves away from
use of -1 for unset/unknown times in ms, which was a
bad choice (it might conflict with real times, such
as a time representing being just behind the start
of a live window).
- Add a few other unset constants, and use them.
- Fix some hardcoding of -1 where existing constants
should have been used.

- Remove getNewPlayingPeriodIndex from MediaSource
- Remove all absolute references to period indices from
Window. Their existence prevents ConcatenatingMediaSource
from being able to efficiently handle children with
large numbers of entries (e.g. a cursor backed source),
since it would copy all windows into its merged timeline.
- Fix ExoPlayerImplInternal to attempt a restart in the
case that the loading (but not yet prepared) period is
removed, in absence of a playing period.
- Implement logic for finding the "next" period in the old
timeline when attempting a retry.
Removing some of the nasty US<->MS conversions left as a
virtual TODO.

Period transitions can either be to new windows (in which case the default
position for the new window should be loaded) or to the next period of the
current window (in which case the the new period should be played from zero).
Fix the logic for calculating the new period index to load to implement this.
In processManifest, periodsById may contain periods that have been removed from
the manifest, which are still being used by the player (it releases periods on
receiving the source info refresh after processManifest returns). Ignore
periods that have been removed from the manifest when calling updateManifest.

This was always a bit of a hack; for Play Movies. It may well
no longer be necessary, and if not I'd like to think of a nicer
or more general way of doing it. We can always bring it back
if needed.

- This avoids the need to have to use the timeline to
calculate a window duration, which can be awkward.
- Window now represents a window of availability with
an isSeekable flag, rather than a window of
seekability.
- Promoted Timeline and Window to top package; they're
pretty important :).

It's no longer safe to convert END_OF_SOURCE -> duration on
the main therad, since the Timeline from which the duration
is obtained is posted to the main thread, where-as the
buffered position is passed by updating a volatile. Hence
an update to the latter might become visible to the main
thread before the corresponding Timeline.
This change moves the conversion to the playback thread.

This change allows MediaPeriod instances to replace
SampleStream instances when the selection isn't changing.
It also allows MediaPeriod instances to retain a
SampleStream but indicate that the renderer consuming
from it needs to be reset.
The change is used to fix the ref'd bug, and is used to
do the same thing in HLS without the need for the source
to report a discontinuity. Note that reporting discontinuity
could cause unnecessary failure when used as a child of
MergingMediaSource.

If a renderer is reading ahead of the playing period, seeking within the
playing period would fail, because renderers would not be disabled but then try
to read from SampleStreams that have a released period.
Also, in the same circumstances, seeking within the reading period would fail,
because all renderers would be disabled, but their sample streams have already
been read. When they are reenabled they expect to see a format but don't
receive one.
In both cases, seeking can just clear the timeline. This only occurs in rare
circumstances when the player is reading ahead, so the cost of re-preparing
will not be incurred often, and allows the seeking logic to be simpler.

When seekToPeriodPosition found that the seek destination period was already
prepared, it would not disable/re-enable renderers. This was fine if the
playing period wasn't changing, but in other cases the renderers would be left
reading the incorrect streams (and the underlying periods may have been
released).
Also, transition to the buffering state before re-enabling renderers, so that
the renderers are not started until leaving the buffering state.

On an edge case, player may get stuck when the renderers are ready but the buffer doesn't get full enough because of a fatal error in data source. An example state can be created by starting a live DASH stream and switching between normal and slow network connections.

When seeking to the default position in a period, the containing source may
actually return a position in another period. Multi-period live sources can do
this to seek the player to the live edge.
ExoPlayerImplInternal uses the same functionality when the playback position
reaches the end of a period to determine what period/position to play next.
This means that when playback transitions to a multi-period live source from
some other source (playing a concatenation of those two sources), the player
will play the live edge rather than the beginning of the earliest period.

This change merges the duties of FormatEvaluator into
TrackSelection classes, so that both the static and
dynamic parts of track selection are implemented in a
single place.
New feature: Demo app now allows you to enable random
adaptation in the track selection dialog.
Notes:
- It should be quite easy to allow application side
track blacklisting in addition to source side, as an
extension to this. That would effectively allow
applications to do seamless/deferred track selection
by creating a TrackSelection with all tracks enabled,
and then toggling the blacklist flags to select the
ones they want to be active.
- It should be trivial to implement format blacklisting
for DASH and SS as an extension to this. Will do in a
follow up CL.

period ends, which is needed for starting to play a multi-period live stream
that is concatenated on to another period at the live edge.

- TrackSelection now exposes the selected formats, ordered
by decreasing bandwidth. This removes the need for DASH,
SS and HLS to do the sorting individually.
- The change also removes the need to reconstruct TrackSelection
instances with a different group index in various places
(e.g. MergingMediaPeriod).
- This is also a step toward potentially packaging the
FormatEvaluator inside of the TrackSelection (TBD).

This change restores ExoPlayer to its previous behaviour.
I think we'll want a "resetPosition" boolean parameter on
setMediaSource at some point, but no need to add it right
now. Note that this would not always reset to the start
of the source. For a live playback it will reset to the
desired position (normally somewhere slightly behind the
live edge).

In V1 we received complaints that Renderer was too locked down.
In particular, it wasn't possible to implement a Renderer that
wrapped another Renderer, since most of the methods were package
private and final (e.g. enable).
This change defines Renderer as a proper interface, removing
this limitation. A method-reordering-only change will follow
this one, to get things into a nice consistent/sane order in
each of the Renderer classes.

1. Rename "extensions" package to "decoder". It's used by both
text and (should be used by) metadata, so it's no longer just
for extensions.
2. Move Buffer objects move into the decoder package.
3. Rename SubtitleParser and MetadataParser to SubtitleDecoder
and MetadataDecoder respectively, since they extend Decoder.
Ditto for all subclasses.
4. Subtitle and Metadata decoders now throw their own exception
types rather than ParserException.
5. Move MediaCodec classes into a mediacodec package, with the
exception of the concrete audio and video renderers.
6. Create an audio package to hold the two audio renderer classes
plus related util classes.
7. Create a video package to hold the one video renderer class
plus related util classes.
After this change the following nice properties hold:
1. Want a video renderer? Look in the video package. Ditto for
audio, text and metadata.
2. All TrackRenderer implementations use a decoder of some kind
to decode buffers received from the source, so we have
consistent terminology there.

It doesn't look like TrackSelectionPolicy is going to be
useful other than with DefaultTrackSelector, and it's kinda

DefaultTrackSelectionPolicy -> selector.DefaultTrackSelector
TrackSelectionPolicy -> [deleted]
