Changes in this update
* **Enhancements**
* Updated MediaPlayer to solve stability issues
* All capability agents were refined to work with the updated MediaPlayer
* Added the TemplateRuntime capability agent
* Added the SpeakerManager capability agent
* Added a configuration option ("sampleApp":"endpoint") that allows the endpoint that SampleApp connects to to be specified without changing code or rebuilding
* Added very verbose capture of libcurl debug information
* Added an observer interface to observer audio state changes from AudioPlayer
* Added support for StreamMetadataExtracted Event. Stream tags found in the stream are represented in JSON and sent to AVS
* Added to the SampleApp a simple GuiRenderer as an observer to the TemplateRuntime Capability Agent
* Moved shared libcurl functionality to AVSCommon/Utils
* Added a CMake option to exclude tests from the "make all" build. Use "cmake <absolute-path-to-source>
-DACSDK_EXCLUDE_TEST_FROM_ALL=ON" to enable it. When this option is enabled "make unit" and "make integration" still could be used to build and run the tests
* **Bug fixes**:
* Previously scheduled alerts now play following a restart
* General stability fixes
* Bug fix for CertifiedSender blocking forever if the network goes down while it's trying to send a message to AVS
* Fixes for known issue of Alerts integration tests fail: AlertsTest.UserLongUnrelatedBargeInOnActiveTimer and AlertsTest.handleOneTimerWithVocalStop
* Attempting to end a tap-to-talk interaction with the tap-to-talk button wouldn't work
* SharedDataStream could encounter a race condition due to a combination of a blocking Reader and a Writer closing before writing any data
* Bug-fix for the ordering of notifications within alerts scheduling. This fixes the issue where a local-stop on an alert would also stop a subsequent alert if it were to begin without delay
* **Known Issues**
* Capability agent for Notifications is not included in this release
* Inconsistent playback behavior when resuming content ("Alexa, pause." / "Alexa, resume."). Specifically, handling playback offsets, which causes the content to play from the start. This behavior is also occasionally seen with "Next" /
"Previous".
* `ACL`'s asynchronous receipt of audio attachments may manage resources poorly in scenarios where attachments are received but not consumed.
- 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
- Implemented `setOffSet` in `MediaPlayer`.
- Updated `LoggerUtils.cpp` to address
(https://github.com/alexa/avs-device-sdk/issues/77).
- Bug fix to address incorrect stop behavior caused when Audio Focus
is set to `NONE` and released. This addresses
(https://github.com/alexa/avs-device-sdk/issues/129).
- Bug fix for intermittent failure in `handleMultipleConsecutiveSpeaks`.
- Bug fix for `jsonArrayExist` incorrectly parsing JSON when trying
to locate array children.
- Bug fix for ADSL test failures with `sendDirectiveWithoutADialogRequestId`.
- Bug fix for `SpeechSynthesizer` showing the wrong UX state when a
burst of `Speak` directives are received.
- Bug fix for recursive loop in `AudioPlayer.Stop`.
Changes in this update
- Added a fix to the sample app so that the StateSynchronization event is the first that gets sent to AVS.
- Added a POST_CONNECTED enum to ConnectionStatusObserver.
- StateSychronizer now automatically sends a StateSynchronization event when it receives a notification that ACL is CONNECTED.
- Added make install for installing the AVS Device SDK.
- Added an optional make networkIntegration for integration tests for slow network (only on Linux platforms).
- Added shutdown management which fully cleans up SDK objects during teardown.
- Fixed an issue with AudioPlayer barge-in which was preventing subsequent audio from playing.
- Changed Mediaplayer buffering to reduce stuttering.
- Known Issues:
- Connection loss during listening keeps the app in that state even after connection is regained. Pressing ‘s’ unsticks the state.
- Play/Pause media restarts it from the beginning.
- SpeechSynthesizer shows wrong UX state during a burst of Speaks.
- Quitting the sample app while AudioPlayer is playing something causes a segmentation fault.
- AudioPlayer sending PlaybackPaused during flash briefing.
- Long Delay playing live stations on iHeartRadio.
- Teardown warnings at the end of integration tests.
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 sample app that leverages the SDK.
- Added an implementation of the `Alerts` capability agent.
- Added the `DefaultClient` class.
- Added the following classes to support directives and events in the
`StateSynchronizer`, `EndpointHandler`, and `ExceptionEncounteredSender`.
- Added unit tests for `ACL`.
- Updated `MediaPlayer` to play local files given an `std::istream`.
- Changed build configuration from `Debug` to `Release`.
- Removed `DeprecatedLogger` class.
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.
