- Changes in this update:
- Better GStreamer error reporting. MediaPlayer used to only report `MEDIA_ERROR_UNKNOWN`, now reports more specific errors as defined in `ErrorType.h`.
- Codebase has been formatted for easier reading.
- `DirectiveRouter::removeDirectiveHandler()` signature changed and now returns a bool indicating if given handler should be successfully removed or not.
- Cleanup of raw and shared pointers in the creation of `Transport` objects.
- `HTTP2Stream`s now have IDs assigned as they are acquired as opposed to created, making associated logs easier to interpret.
- `AlertsCapabilityAgent` has been refactored.
- Alert management has been factored out into an `AlertScheduler` class.
- Creation of Reminder (implements Alert) class.
- Added new capability agent for `PlaybackController` with unit tests.
- Added Settings interface with unit tests.
- Return type of `getOffsetInMilliseconds()` changed from `int64_t` to `std::chronology::milliseconds`.
- Added `AudioPlayer` unit tests.
- Added teardown for all Integration tests except Alerts.
- Implemented PlaylistParser.
- Bug fixes:
- AIP getting stuck in `LISTENING` or `THINKING` and refusing user input on network outage.
- SampleApp crashing if running for 5 minutes after network disconnect.
- Issue where on repeated user barge-ins, `AudioPlayer` would not pause. Specifically, the third attempt to “Play iHeartRadio” would not result in currently-playing music pausing.
- Utterances being ignored after particularly long TTS.
- GStreamer errors cropping up on SampleApp exit as a result of accessing the pipeline before it’s been setup.
- Crashing when playing one URL after another.
- Buffer overrun in Alerts Renderer.
- [SampleApp crashing when issuing "Alexa skip" command with iHeartRadio.](https://github.com/alexa/avs-device-sdk/issues/153)
- [`HTTP2Transport` network thread triggering a join on itself.](https://github.com/alexa/avs-device-sdk/issues/127)
- [`HTTP2Stream` request handling truncating exception messages.](https://github.com/alexa/avs-device-sdk/issues/67)
- [`AudioPlayer` was attempting an incorrect state transition from `STOPPED` to `PLAYING` through a `playbackResumed`.](https://github.com/alexa/avs-device-sdk/issues/138)
Changes in this update
- Added `AudioPlayer` capability agent.
- Supports iHeartRadio.
- `StateSynchronizer` has been updated to better enforce that `System.SynchronizeState`is the first Event sent on a connection to AVS.
- Additional tests have been added to `ACL`.
- The `Sample App` has been updated with several small fixes and improvements.
- `ADSL` was updated such that all directives are now blocked while the handling of previous `SpeechSynthesizer.Speak`
directives complete. Because any directive may now be blocked, the `preHandleDirective() / handleDirective()` path
is now used for handling all directives.
- Fixes for the following GitHub issues:
- https://github.com/alexa/alexa-client-sdk/issues/44.
- A bug causing `ACL` to not send a ping to AVS every 5 minutes, leading to periodic server disconnects, was fixed.
- Subtle race condition issues were addressed in the `Executor` class, resolving some intermittent crashes.
Changes in this update
- Added a getConfiguration() method to DirectiveHandlerInterface to register Capability Agents with Directive Sequencer.
- Fix race condition with reading attachments before a writer exists.
- Use of new Logging abstraction layer in modules - ADSL,AFML,ContextManager,AuthDelegate,AIP,KWD,Mediaplayer.
- Added ACL stream processing with Pause and redrive.
- Removed the dependency of ACL Library on Authdelegate.
- Added and interface to allow ACL to Add/Remove ConnectionStatusObserverInterface.
- Fixed compile errors in KittAi, DirectiveHandler and compiler warnings in AIP test.
- Corrected formatting on the files.
- Fixes for the following Github issues
- https://github.com/alexa/alexa-client-sdk/issues/21
- https://github.com/alexa/alexa-client-sdk/issues/25
Changes in this update:
- Added the SpeechSynthesizer, an implementation of the SpeechRecognizer capability agent.
- Implemented a reference MediaPlayer based on [GStreamer](https://gstreamer.freedesktop.org/) for audio playback.
- Added the MediaPlayerInterface that allows you to implement your own media player.
- Updated ACL to support asynchronous receipt of audio attachments from AVS.
Bug Fixes:
-Some intermittent unit test failures were fixed.
Known Issues:
-ACL's asynchronous receipt of audio attachments may manage resources poorly in scenarios where attachments are
received but not consumed.
- When an AttachmentReader does not deliver data for prolonged periods MediaPlayer may not resume playing the
delayed audio.
