# 4.5.0

---
## Added

* Added ``ConvivaPlugin.MetadataBuilder`` with an option to exclude audio bitrate from Conviva average bitrate metrics.
* Avoid mutating local Conviva metadata when starting a Cast session.
* Added support for IMA client ads in ``SingleControllerPlaylist``.

## Changed

* ExoPlayer updated to 2.19.1
**Note** that ``PlayerController`` must be accessed from a single application thread which is for the vast majority of 
cases and currently the application's main thread only. The Looper of the thread from which the ``PlayerController`` must be 
accessed can be queried with ``PlayerController.getPlayerLooper``. APIs that can be accessed from any thread are explicitly marked as such.
* ``CastlabsPlayerException`` now uses ``TYPE_DRM_EXCEPTION`` for communication errors with non-DrmToday backends,
  replacing ``TYPE_DRMTODAY_EXCEPTION``. (**Behaviour Change**)
* Fixed serialization of open and release in ``SingleControllerPlaylist``.
* Fixed ``PlayerController.isLive`` incorrectly reporting ``true`` on startup for VOD streams played within ``SingleControllerPlaylist``.
* Fixed an issue with closed DRM placeholder session.

* Fixed a crash when initializing the SDK on devices with API 22.

# 4.4.9

---
## Changed

* Fixed an issue which provoked some MP4 WebVTT subtitles not to clear out the last sample.
* Updated playback start buffering logic so it no longer waits for segmented subtitle loading. (**Behaviour Change**)
* Replaced ``PlayerSDK.ENABLE_FATAL_RETRY_MIME_APPLICATION`` with ``PlayerSDK.FORCE_TEXT_FATAL_EXCEPTION`` 
 to control whether a fatal error ``PlayerSDK.TYPE_DOWNLOAD_ERROR`` or a warning 
 ``PlayerSDK.TYPE_DOWNLOAD_WARNING`` is raised when text downloads fail. (**API Change**)
* HybridAdPlayerPlugin now raises ``CastlabsPlayerException.TYPE_DOWNLOAD_WARNING`` instead of 
 ``CastlabsPlayerException.TYPE_DOWNLOAD_ERROR``. (**API Change**)

* Fixed a potential crash in tunneled video playback when reinitializing the codec.
* Updated muxcore to 8.7.0
* Updated Google IMA SDK to 3.37.0 (**Breaking Change**): Applications using the IMA plugin
 now require core library desugaring to be enabled. See the Extensions manual section for complete

  This method of encryption uses a Castlabs specific `Encryptor` at the IPTV Client Headend.

# 4.4.5

---
## Added

* Expose DRMToday ``traceId`` through `DrmTodayException#getTraceId()`. This might result useful for
  debugging or analytics. Check the manual at the DRM Protection > Troubleshooting section.

  the current bandwidth estimation to its initial value automatically upon item transition.
* [Experimental] Added Support for Widevine and Playready encrypted AAC-ADTS, AAC-LATM and AC3 Multicast Content. 
  This method of encryption uses a Castlabs specific `Encryptor` at the IPTV Client Headend.
* Added ability to control ``PlayerSDK.AUDIO_CODEC_FILTER`` behavior independently from Video, similar to
  ``PlayerSDK.VIDEO_CODEC_FILTER``. The default value of the same is set to ``SdkConsts#AUDIO_CODEC_FILTER_CAPS``.
* Added ``PlayerSDK.AD_SETTINGS`` to configure ad playback behavior. The ``creativeFormatFallback``
  setting allows specifying a fallback format (Progressive, HLS, DASH, etc.) for ad creatives when the
  format cannot be detected from the URI. By default, ad creatives without detectable formats will
  now fallback to Progressive (**Behaviour Change**).
* Added support for Broadpeak Server-Side Ad Insertion (SSAI) streams. Check the Broadpeak section
  in the Extensions part of the manual for more information.

## Changed

* Improved DRM initialization performance.

 Labels for DRM names and disabled audio and text can be customised.
* Added automatic fallback when audio passthrough output is changed.
* Fixed a stacktrace-printing error that could happen when releasing the player when it was still  
 processing ``ThumbnailTracks``.
* Fixed an issue where the IMA ad overlay could remain visible after releasing and reopening
 the player while preserving the view surface.
* Broadpeak: Improved session release flow. Fixed potential ANRs when Broadpeak's Smartlib was unresponsive.
* Added thumbnail disk cache configuration via ``ThumbsPlugin.setDiskCacheMode(...)``.
 Caching is turned off by default now (**Behaviour Change**).

* Fixed memory leak caused by ``DebugPlugin`` Overlay.
* Reworked ``DebugPlugin`` (**API Change**) (**Behaviour Change**). Some setter methods now are not 
 applying at runtime anymore. Check the API docs for details on how to apply. ``showDebugOverlay`` and
 ``hideDebugOverlay`` have been removed from ``DebugPlugin`` and alternative APIs are in ``OverlayControllerComponent``.
* Improved ``DownloadService`` stability when started from background on devices with strict 
 background execution limits.

# 4.2.86

---
**Changes**

* Fix to avoid freeze when total number of ADs in a Pod unexpectedly decrements without notification
* Added support for ``dashif:Laurl``. In this case ``DrmConfiguration`` may not be provided to the player at all,
as it does not require to have any DRM URL. When ``DrmConfiguration`` is provided and it contains DRM URL then it overrides ``dashif:Laurl``,
check the manual for more details in DRM Protection, section DRM URL.
* Added customizable ``PlayerSDK.DEFAULT_DRM_CONFIGURATION`` to configure DRM when the one is not provided by the application.

 This configuration can cause further delay in stream loading since we attempt to seek closer to the Live Edge when 
 specified. 
* Add ``ThumbnailProvider.cancelRequests`` method to cancel explicit queued Requests. Note that this
 won't cancel any already in-flight request.
* The content type of M4A and M4V is now automatically detected, eliminating the need for manual definition.

 as a list. This listener could be added by the ``addEventStreamListListener`` method of the PlayerController.
* Added ``RequestQueuePosition`` for ``ThumbnailProvider``. By setting the ``RequestQueuePosition`` to ``AddFront``, 
 thumbnail requests will be enqueued at the beginning of the loading queue.
* Improved the stability of ``ThumbnailProvider``.
* Fixed wrong DASH thumbnail URL calculation for live streams. Regression introduced in 4.2.81.

* Added ``InitialPositionProvider.snapToSegmentStart`` to snap to the previous sync point (**API Change**)
* ``disableAutoFlowText`` property is added to the ``SubtitlesStyle`` and If set to true the auto-flow text
behaviour will be disabled regardless of the font-size and the font-scale.
* Added Media MimeType reporting for ``VideoTrackQuality``, ``AudioTrack`` and ``SubtitleTrack``. This
 informs about the *media* mime type in opposition to the *codec* mime type which was already present in the model.

In order to revert to not setting Surface Framerates you may disable it by setting ``PlayerController.setChangeFramerateStrategy`` to
``VIDEO_CHANGE_FRAME_RATE_STRATEGY_OFF``. Applications wishing to use ``Surface#CHANGE_FRAME_RATE_ALWAYS`` should set the mode to
VIDEO_CHANGE_FRAME_RATE_STRATEGY_OFF to disable calls to Surface#setFrameRate from the player, and should then call Surface#setFrameRate
directly from application.

---
**Changes**

* Fixed regression when playback in tunnelling mode can not be started on devices with API >= 23

and the playback continues in non-tunneling mode (**API Change**)
* Improved behaviour of ``ThumbnailProvider.getThumbnail``: now thumbnails will always be resolved
 precisely, multiple calls can be invoked in parallel without waiting for preceding ones and callbacks
 will always be invoked, even if the data couldn't be fetched or the request gets cancelled. Explicit
 thumbnail requests will also take precedence and prioritized over the background thumbnail loads.
* Added multithreaded Thumbnail loading. Default is 2 threads. Configurable via
 ``ThumbsPlugin.setThumbnailLoadThreads`` before playback start.

# 4.2.72

---
**Changes**

* Thumbnail loading order now prioritizes the current playback position.
* Player release and Surface setting timeouts. This helps avoiding ANRs as a workaround in case an
 underlying component, such as a decoder, is unresponsive. Timeouts are configurable through ``PlayerSDK``.
* Fixed an issue where the ``CatchupConfiguration`` might be applied to VoD streams if using ``SingleControllerPlaylist``.
* Fixed ``PlayerController``'s ``isLive`` method. It previously reported whether the current Window
  was expecting a manifest update, which didn't necessarily represent whether a stream was live or not. (**Behaviour Change**)

# 4.2.71

---
**Changes**

* [IPTV] Sync -Ensure Audio of content is only passed after Video even if Audio is ahead.
* Playback will be paused if all the qualities are not playable due to HDCP restrictions (**Behaviour change**)

* Added support for bandwidth estimation parsing out of CMSD headers. This feature has to be enabled
 in the ``AbrConfiguration``.
* Fixed ``ResponseModifiers`` not accumulating modifications from successive modifiers.
* Added ``HybridController`` support to enable DVB/IPTV playback with WVCAS Support. This requires the 
 device to be TunerFramework compatible. This also requires the CastLabsServiceApplication to be installed 
 on the device /system/priv-app folder which requires System privileges to operate. Example usage can be 
 found under the examples/hybrid_demos application.
* Fixed ``PlayerController`` deadlock when calling ``release`` when transitioning to ``Preparing`` state.
* Fixed potential ANR when releasing the ``PlayerController`` during thumbnail loading
* When using the ``MultiControllerPlaylist`` the analytics data reports only for the current item. This behavior

 on the SDK manual for more information. The default thumbnail preloading has been improved to use
 a ``LoadingStrategy`` which doesn't load thumbnails sequentially anymore (**Behaviour change**).
* Vastly improved parsing times for VTT subtitles. The improvement is more noticeable with larger
 VTT files and slower devices.
* Added DRM `RetryConfiguration` used in license requests. The default is no retries.
* Fixed side-loaded Thumbnails sometimes not properly initialized. Deprecated the use of
 ``ThumbnailDataTrack`` for configuration purposes. Now ``SideloadedTrack`` should be used alongside
 with ``SdkConsts.INTENT_SIDELOADED_TRACKS_ARRAYLIST`` instead. Check the Thumbnails section in the
 SDK manual for more info and examples.

updating your app's ``targetSdk`` to 30. For more information check out the "Scoped Storage" section
in manual, under Extensions, Downloader. If you are affected by this, you can go ahead and perform
the migration on your side and update the references in the SDK with the new ``updateDownloadPath``
method. We are also currently working on endowing the Downloader with migration utilities,
which will be published in a future release.

---
**Known Issues**

 * There's a known issue when using `SingleControllerPlaylist` in conjunction with Audio Tracks

# 4.2.4

---
**Important Change**

This release adds support for 64bit native code to all plugins including the OMA plugin. It also
updates the OMA plugin so permit targeting Android API >= 23 with. That means you no longer
need to split APKs when you are using OMA and you also no need to filter for an
64bit native libraries.

---
**Changes**

 * Added `VideoRendererListener` to get information about decoder initialization times and types
   as well as general decoder callbacks and dropped frame information
 * Improved `PlayerController` stability in multi-threaded context
 * Fixed an issue preventing `TrickplayConfiguration` to be applied on playback start.
 * Added `Intent` param to enable Trickplay mode; `SdkConsts.INTENT_TRICKPLAY_ENABLED`. Available also
 in the `PlayerConfig` as `enableTrickplayMode`.
 * Better integration between `TrickplayConfiguration` and playlists. Now there's a flag to automatically
  carry over the current `TrickplayConfiguration` onto the next `PlayerController`. See
 `Playlistcontroller.KEEP_TRICKPLAY_CONFIG`.
 * Added option to preserve the `Surface` of the `PlayerView` for multiple playbacks. This provides
   potentially better performance when new content is loaded as the surface does not need to be
   re-created and allows to keep the last frame on screen while the decoder is disposed. This
   feature can be enabled with `SdkConsts.INTENT_PRESERVE_PLAYER_VIEW_SURFACE` or via
   `PlayerConfig.preservePlayerViewSurface`.
   If you want to preserve the surface but still render a black screen when the decoder is
   disposed, you can use `SdkConsts.INTENT_PUSH_BLACK_SCREEN_ON_DISPOSE` or
   `PlayerConfig.pushBlackScreenOnDispose` to let the decoder push a black frame when disposed.
   Please note that pushing black frames is only supported on API >= 19.
 * Added 64bit native binaries. **Note** that this might have implications
   on your build and you might be able to remove any ABI filters (**Build Change**)
 * Add support for target API >= 23 for the OMA Plugin
 * Fixed an issue which provoked some built-in device screens to be detected as secondary screens
 and thus prevented playback when the `PlayerSDK.SECONDARY_DISPLAY` flag was set to
 `SdkConsts.SECONDARY_DISPLAY_NEVER`.
 * Fixed an isue with Broadpeak Plugin which prevented from performing content redirection
 for sessions other than the first one.
 * Fixed issue where Manifest load retries were not reported correctly
 * Fixed issue with stale CDN switches
 * Added new `CastlabsPlayerException.TYPE_MANIFEST_PARSING_FAILED` error type to identify
   manifest parsing errors and loaded but invalid manifests
 * Fix playback position not reported when seeking while paused.
 * Fix modifying fields of the `TrickplayConfiguration`, such as `preferTrickPlayTracks`, not taking
 effect if modified while in playback.
 * Moved `PlaylistController` to the `com.castlabs.android.player.playlist` package, please
 change your import statements (**API Change**).
 * Implemented `PlayerController` pooling, allowing to re-use them and allowing for more advanced
 features in the `PlaylistController`.
 * New `PlaylistController.Builder`, which should be used to create an instance of `PlaylistController`
 (**API Change**).
 * `PlaylistController` supports now background playback. This is intended to use for a "live channel"
 use case. Keep in mind this feature will consume high amounts of bandwidth and requires more than
 one decoder on the device. Have a look at the `backPlayers` and `forwardPlayers` settings in the
 `PlaylistController.Builder` to enable this feature.
 * Added flag to move the current `TrickplayConfiguration` from one item to the next one:
 `PlaylistController.KEEP_TRICKPLAY_CONFIG`.
 * Playback will jump to the previous item (in playlist order) when playback position reaches 0
 and playing at a negative speed (**Behaviour Change**). Note that if you want to force a specific
 playback position when this happens, you'll still need to add a `PlaylistListener` listener and
  implement your logic in the `onItemChange` method.

# 4.2.3
 * Added Dash CDN switching mechanism (**API Change**) (**Behaviour Change**)
 * Added the ability to controll the DASH manifest update duration in the `LiveConfiguration`
 * Allow to overwrite manifest update period for DASH live streams

 * Fixed PlayerViewController buttons availability and focusability depending on available tracks.
 * Fixed an issue when directly destroying a PlayerController attached to a PlayerView.
 * Added `PlaylistListener.onPlaylistEndReached` which will be notified on Playlist completion. (**API Change**)
 * Added `PlaylistController.AbstractPlaylistListener` as a convenience default implementation for the
 `PlaylistController.PlaylistListener` interface.
 * Apply subtitle margins also for image-based subtitles.
 * All `PlayerViewPlugin`s depend now on the `PlayerView`, and all the View-providing plugins can now work
 without the corresponding `PlayerViewPlugin`. This way you can use any plugin such as `SubtitlesPlugin` or
 `ThumbsPlugin` without a `PlayerView`.
 * Deprecated `SubtitleViewWrapper`. Create a `SubtitlesView` either programmatically or by defining it
 in a layout, and set it to the `PlayerController` through its `setComponentView()` method.
 * Fixed issue with live edge delay on some streams
 * Added "Advanced Setup" chapter to our manual. Here we explain how to tweak live and low latency-
 related settings.
 * Added `PlaylistController.setItemChangeFlags()` method. This allows to configure the behaviour
 when changing playlist items. You can dictate whether to keep selected tracks and quality or not, and
 to carry over the last bandwidth estimate to the new `PlayerController`.
 * Added option to read screen dimensions using the legacy approach. This is found to workaround some
 device resolution detection issues in some STBs. To enable this for a device, use the static method
 `PlayerSDK.addLegacyDeviceScreenResolution("Manufacturer", "Model")` in your SDK setup code.

# 4.2.1
 * Added `PlayerConfig` object as an option to start playback, which deprecates `PlaybackState` (**API Change**).
 * Added Kotlin extensions for Player configuration. Have a look at the new ``Kotlin`` section in the SDK manual.
 * Added `PlayerSDK.ENABLE_TRICK_MODE_TRACK_SWITCH` option to use DASH trick mode tracks (**API Change**) (**Behaviour Change**)
 * Added `onFullyBuffered` method to `PlayerListener` interface. (**API Change**)
 * Added playlist support through the `PlaylistController`.
 * Fixed Surface management issues when re-using a `PlayerView` across different `PlayerControllers`.
 * Added `INTENT_CLIPPING_START` and `INTENT_CLIPPING_END` in order to clip the start and/or end times.
 * Added `Track.LABEL_LOCALE` to customize in which Locale the Subtitles and Audio track Locale labels are displayed.
   Defaults to current system Locale.
 * Fixed an issue which made the same SubtitleView to be re-used across multiple PlayerControllers.
 * `LiveConfiguration.liveEdgeLatencyMs` now also affects HLS streams. If informed, the HLS-specific
   `LiveConfiguration.hlsLiveTailSegmentIndex` param will be ignored. (**Behaviour Change**)
 * Avoid unnecessary codec reconfiguration on video quality change

# 4.2.0
 * Updated Exo to r2.8.0
 * Added `DrmDeviceTimeCheckerPlugin`. This plugin will perform periodic checks related to DRM licensing.
   It workarounds a Widevine limitation by performing time-related checks while playing protected content.
 * Set `AbrConfiguration` minimal duration of the buffer to retain after discarding the segments (**API Change**)
 * Added `PlayerSDK.SSL_KEY_STORE` to add custom SSL key store as secondary to the system default one (**API Change**)
 * Updated IMA to 3.8.5, improved performance and refactored IMA plugin and ads interfaces (**API Change**) (**Behaviour Change**)
 * Added `setMaxVideoSizeFilter` method in `PlayerController` which allows to change the maximum
   resolution for the ABR algorithm while in playback.
 * Added `DrmLicenseLoader.remove` in order to remove locally stored DRM licenses. Currently only available
   for Widevine.
 * Fixed offline license fetching on un provisioned devices.
 * Improved support for Ultra Low Latency streams. Added `getLiveEdgeUs`, `getPositionInPeriod` and
   `setPositionInPeriod` methods in `PlayerController`. Catchup behaviour improved.
 * Added debugging charts. These are found in the "debug_plugin". `PlayerStateChart` shows the player
   state history and `PlayerMetricChart` can show various player metrics. You can enable a default overlay
   with the `DebugPlugin`'s `debugOverlay` method. You can also create your own `Metric`s to be drawn
   by the `PlayerMetricChart`.
 * Moved `onVideoFormatChange` and `onAudioFormatChange` methods out of `StreamingEventListener` into new
   `FormatChangeListener` interface. (**API Change**)
 * Added castLabs `Log` class. It allows to set the log level in order to hide certain log mesages,
   and to register `Loggers` that will receive all castlabs logs messages - regardless of the log level.
 * Added `getBackBufferTime()` method to `PlayerController`. This returns the oldest position
   that still has buffered content. A seek operation to a position >= getBackBufferTime should
   be quick since the media is still present in the buffer, and won't trigger content re-download.
   This is configurable through the `BufferConfiguration`.
 * Content load retry errors won't be fired as a Warning exception anymore. (**Behaviour Change**)
 * Content load retry attempts can be retrieved with via the `StreamingEventListener`. (**API Change**)
 * Fixed PNG subtitles not showing when defining `backgroundImage` and `duration` in different xml tags.

   a `PlayerView`. Added optional `SubtitleViewWrapper` custom view to take care of listening for
   the `SubtitlesView` to be ready.

# 4.1.11
 * Added `drainWhileCharging` property to `BufferConfiguration`. If this flag is enabled will prevent
   the buffer from draining if the device is charging. Enabled by default (**Behaviour Change**).
 * Added CEA608 support in CL subtitles plugin (**API Change**)
 * Updated NDK to r16b

# 4.1.10
 * Added support for live CMAF low latency.
 * Added `LowLatencyProfile` to easily set params for a low latency scenario.

 * Added option to force a custom UTCTimingElement for DASH streams.
 * Updated Youbora integration to 6.1.5 (**API Change**)
 * Added `PlayerSDK.DUMMY_SURFACE_MODE` to force disable dummy surface on some devices.
   This can be together with the IMA plugin to prevent issues where the decoder can not be initialized
   properly.

# 4.1.9
