Some other minor nits and adjustments to the API logic.

We wait until a previous AudioTrack has been released before
creating a new one. This is currently done with a thread
block operation, which may cause ANRs in the extreme case
when someone attempts to release the player while this is
still blocked.

The problem can be avoided by just returning false from
DefaultAudioSink.handleBuffer to try again until the previous
AudioTrack is released.

Reproduction steps to force the issue:
1. Add Thread.sleep(10000); to the AudioTrack release thread.
2. Add this to the demo app:
    private int positionMs = 0;

    Handler handler = new Handler();
    handler.post(new Runnable() {
      @Override
      public void run() {
        player.seekTo(positionMs++);
        if (positionMs == 10) {
          player.release();
        } else {
          handler.postDelayed(this, 1000);
        }
      }
3. Observe Player release timeout exception.

These steps can't be easily captured in a unit test as we can't
artifically delay the AudioTrack release from the test.

The SDR constant also specified a color space and range, in addition to
C.COLOR_TRANSFER_SDR. However, it turns out that SDR videos may use different color
space and range values, so following prior ExoPlayer conventions to have `null`
mean "generic SDR" is preferable here.

If the input is HDR (HLG), check encoder capabilities for HDR support
and request tone-mapping to SDR during decoder configuration otherwise.
Capabilities are only checked for API 31 and above, as HDR editing is
not supported before.

As the encoder capabilities check needs to happen before selecting the
encoder to use (as this may depend on the resolution output by the
effects chain), the EncoderWrapper checks all candidate encoders
for the MIME type for HDR capabilities and only requests fallback to
SDR if none of them support it.

When the actual encoder is selected, the wrapper checks that it matches
one of the encoders is checked capabilities for.

Configure the GL shaders and encoder to take in HDR metadata.

This mostly just consists of passing the Format.colorInfo through
the VideoTranscodingSamplePipeline down to the encoder, rather than passing
the PQ-ness down to the GL step.

Due to b/237674316, this will remove HDR10+ support temporarily to introduce
support for HLG10.

Manually tested to confirm that HLG10 operations that don't affect color display
correctly after this CL with "HDR editing" in the demo checked, and continue to display incorrectly (as before this CL) without the option unchecked.

The old getString() will throw because FRAME_RATE can only be float or int.

ProgressiveMediaPeriod loads all available tracks into SampleStreams
(because it needs to read the data anyway and it allows easy activation
of tracks without reloading). However, the SampleStreams for disabled
tracks are not read and no one if waiting for them.

The buffered position is used for user-visible state (e.g. in the UI)
and to check how much data is already buffered to decide when to stop
buffering (using LoadControl). Both values benefit from only
using the actually enabled tracks to better reflect what is available
for playback at the moment.

We used "ALL_COOECS" previously, and it is not necessary because "ALL_CODECS"
additionally the codecs that support tunneling/secure decoding, which there
is no use case in Transformer.

Although MediaCodec claims supporting float frame rate, encoder init failed on
API21 Nexus 5. Since it's just a performance hint to the codec, it's OK to
generalize it to other API versions.

- Improve variable naming to include time units for clarity
- Fix existing timestamp calculations to respect time units as well as track tempo (default values for now)
- Ensure the synthesizer produces PCM for the correct amount of time (including gaps between commands).

As per MP4 spec, bitrates in esds boxes can be a 32 bit number which doesn't fits in Java int type, so now reading it as a long value. Our class for holding media format, only allows bitrates value to be an int as we don't expect the bitrates to be greater than or equal to 2^31. So we're limiting the values for bitrates to Integer.MAX_VALUE.

The GlEffectsFrameProcessor that will be part of the effects module
uses the DebugViewProvider. So it does not make sense for it
to be an inner interface of Transformer.

surface is only replaced when it is not being rendered to and vice

The outputHeight in the TransformationRequest is the height of
the frame as it would be displayed (i.e., after applying any
rotation specified in the format). So pass-through should only
be used if the requested outputHeight matches the input
format's height after applying the rotation.

Previously two timelines that differed only in shuffle order were
considered equal, which resulted in no call to
Player.Listener.onTimelineChanged when calling
ExoPlayer.setShuffleOrder. This in turn resulted in no call to
MediaControllerCompat.Callback.onQueueChanged.

Also make a small fix inside ExoPlayerImpl.setShuffleOrder, to ensure
that the new shuffle order is used when constructing the masked
timeline.

NoUidTimeline still exists as a private detail of TestUtil, but it no
longer extends ForwardingTimeline because the interactions are quite

1. The offloadSchedulingEnabled value doesn't need to be in
   PlaybackInfo because it's never updated in EPII.
2. The sleepingForOffload value in EPII wasn't updated explicitly
   (just via the return value of a method). It was also only
   meant to be enabled while the player is actively playing, but
   confusingly triggered from a path where the player may
   theoretically be buffering as well.
3. The offload sleeping (=not scheduling doSomeWork) was interwoven
   into the actual scheduling code making it slightly hard to follow.
   This can be improved slightly by keeping the offload sleeping
   decision and the scheduling separate.
