In startTransformation method we were throwing UnsupportedEncodingException (IOException) when mediaItem with unsupported arguments is passed.
Changed this to IllegalArgumentException which seems more logical here.

This is the follow-up commit where the onEvents callback

This ensure that ffmpeg error code are properly translated to values that the ExoPlayer decoder understand.
The main gain is that it allows the decoder to properly ignore more cases of invalid data and recover.
The second gain is that the other errors are now proper ExoPlayer errors and no more obscure buffer ones.

This logic is currently in the player renderers. With multi-asset, the
renderers will go into the AssetLoader, which shouldn't be responsible
for muxing.

PiperOrigin-RevId: 486860502

Problem: We are initialising muxer as soon as we start the transformation. Now the startTransformation() method can be called from main thread, but muxer creation is an I/O operation and should be not be done on main thread.

Solution: Added lazy initialisation of muxer object. The actual transformation happens on background thread so the muxer will be initialised lazily from background thread only.

Another way was to provide an initialize() method on MuxerWrapper which will explicitly initialise muxer object but with this approach the caller need to call the initialise method before calling anything else. With current implementation the renderers are calling MuxerWrapper methods on various callbacks (Not sequentially) and also we are sharing same muxer with multiple renderers so It might become confusing for the caller on when to call the initialise() method. Also there are few methods on MuxerWrapper which dont really need muxer object. So in short it might make MuxerWrapper APIs more confusing.

Validation: Verified the transformation from demo app.

This should be necessary to ensure decoders see fewer errors.

Setting this resulted in removing native_dequeueOutputBuffer errors on OMX.MTK decoders for in-app tone mapping prototyping.

The method getCurrentPosition() may return a lesser position during pause than the previous retrieved value due to ipc call delay in playerInfo update. Users see track position jump backwards at pause. Fixed to return last estimated position while paused if have not received updated playerInfo. Code is deduped to point getContentPosition() to getCurrentPosition() when !isPlayingAd.

* Add `Listener` in `MediaSession` with method `onNotificationRefreshRequired(MediaSession)`.
* Add `MediaSessionService` as the listener of the `MediaSession` when `MediaSession` is added to `MediaSessionService`
* Load bitmap when update metadata in `MediaSessionLegacyStub` and call `onNotificationRefreshRequired` when bitmap asynchronously arrives.

If an app sets a compileSdkVersion that is lower than the one used to
create AARs of its dependencies, the build process may produce invalid
outputs, for example by stripping methods from the APK that are only
called when the app is running on a new API version.

To avoid this issue, we can enforce that the compileSdk of apps or
libraries depending on ExoPlayer/Media3 is at least the same as the
one we used for compilation when creating the AAR.

This root extra needs to be set by apps manually in media1 and we
can do that automatically in Media3 based on the available session
commands.

#minor-release

PiperOrigin-RevId: 484286833

In Media3 there is the useful concept of connection hints that a
client can set when building the session and that are sent to the
service and passed to the `Callback.onConnect()` method when the
browser connects.

These connection hints are then included in the `ControllerInfo`
object that later will be passed to every callback method and the
implementor can then take decisions specific to these connection
hints.

These connection hints are not available in media1. However, when
an app creates a `MediaBrowserCompat` object, the constructor takes
a rootHint object that is sent to
`MediaBrowserServiceCompat.onGetRoot()`.

This change uses the browser rootHints as the connection hints when
creating the `ControllerInfo` for legacy browsers and makes them
available to the `MediaLibrarySession.Callback` domain methods in
the same way as connection hints of a Media3 browser.

This change makes adding ad events in live streams more robust by allowing ad
groups to grow in number of ads if more ad events are received than initially
announced by the SDK.

With the IMA prefetch feature, an AdPod can grow in size in certain conditions
like from initially 2 ads to 4 ads being part of the ad group. With this change,
if an additional ad event arrives while the ad group is still being played,
the ad group is expanded. If the event arrives late and the ad group is already
completed, a new group is created for the remaining ads.

This also covers the case where we join the live stream while an ad is being
played and we missed at least one LOADED event from the SDK. Ads of the group
before the first LOADED event are ignored in such a case.

From ANSI-CTA-608-E R-2014 section 8.4:

This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.

The `isMiscCode`  method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.
