- 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 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 the CapabilityAgent base class that is used to build capability agent
implementations.
- Added the ContextManager class that allows multiple Capability Agents to
store and access state. These events include context, which is used to
communicate the state of each capability agent to AVS:
- Recognize
- PlayCommandIssued
- PauseCommandIssued
- NextCommandIssued
- PreviousCommandIssued
- SynchronizeState
- ExceptionEncountered
- Implemented the SharedDataStream (SDS) to asynchronously communicate data
between a local reader and writer.
- Added AudioInputProcessor (AIP), an implementation of a SpeechRecognizer
capability agent.
- Added the WakeWord Detector (WWD), which recognizes keywords in audio streams.
v0.3 implements a wrapper for KITT.ai.
- Added a new implementation of AttachmentManager and associated classes for use
with SDS.
- Updated the ACL to support asynchronously sending audio to AVS.
