Message bus config loading is now shared by service and client.
messagebus.client.ws file is still available in case skills are using it. It is a backport that inherits from the new MessageBusClient class. Adds depreciation warning.
pychromecast needed to be updated to fix pip package version conflict
when using streaming google STT.
Minor issues with startup of audio needed to be handled, mainly adding
explicit waits to ensure commands would be accepted
the old "__metaclass__" has been ignored since the switch to python 3
this restores the metaclass functionality by updating it to the new
class kwarg syntax
The simple audio service can be paused. The audio is "paused" but placing the
audio playback mechanism (usually aplay or mpg123) into the background, kinda
like hitting Ctrl+Z. While in the background that process can no longer react
to the SIGTERM signal. So paused audio has to be brought to the foreground
using SIGCONT, and _then_ sent SIGTERM.
Also added a belt to go with these suspenders and perform a process.kill() if
the audio process doesn't go away after 1 second.
The message returned is a dict of all available audio backends as keys
containing 'supported_uris' listing supported uri types (file:// http://
etc.), 'remote' (bool) True if remote), 'default' (bool) true if the
default audio backend.
The restore_volume would previously unpause the service even if the user just asked for pausing playback.
This separates the paused flag from the pausing/resuming action so lowering/restoring volume doesn't affect the logical pausing state and can check it to determine if lowering/restoring is needed/wanted.
This adds a very simple mechanism for pausing and resuming audio streams
that are actively playing. The process is suspended and resumed when
requested.
This also uses that same method to implement lower_volume()/restore_volume() for simple "ducking" of audio.
* Refactor mimic2 to use the shared tts architecture
* Make sure the queue is cleared
- Add a convenience method grouping clear_queue and clear_visemes
- The start time is now set before the lock to allow multiple speech requests queued before the stop signal to also be cancelled
- Make sure the any pending TTS generation is cleared from the queue by calling tts.clear() when breaking from the chunking loop.
- Adds RemoteAudioBackend class, which is used to differentiate between
Remotes and local audio backends
- When searching for audio backends the backends are storted to first
check local ones and secondly remote ones
The audioservice can now jump forward and backward in the audio stream/file
The functionality is accessed via the audioservice class's seek_forward(),
seek_backward() and seek() methods
The common play skill sends a stop message in the CPS_start(), if the play message is sent too close to the stop message it may be executed before the stop message causing playback to immediately stop.
To circumvent this a 1 second stop ignore time is added.
* Add repeat option to audioservice
The audioservice.play() method now accepts a repeat parameter. If this
parameter is True the playlist passed to the audio service will be
repeated.
* Add repeat support to vlc
* Add the repeat parameter to all services
Not functional but playback will work at least. Hacktoberfest?
* Use correct method to guess mime type
* Use the commands from mycroft.conf
- Remove hardcoded commands and use the ones from mycroft.util to handle
configurations.
- Improve error handling
This is reimplementation of #1649 which became divergent.
## Description
Adds a Ogg123Service and a play_ogg exactly like Mpg123Service and play_mp3
## How to test
I have a skill for a podcast which does not have an mp3 feed:

This fixes a stray lock.release() causing a silent
RuntimeError: release unlocked lock
after TTS execution but just before reporting the timing for the TTS system.
* Handle stop correctly in the audio service.
This allows for example the news skill playback to be stopped without
the listening being triggered.
* Handle case where service stops at end of playlist
- Fix issue when receiving multiple stop signals
- Stop method of services now returns True or False depending on if audio was playing
The Mark 1 button press can now be "consumed" when a skill handles
the Stop command. When this happens, the button press will not
trigger listening mode. An additional press would be needed to
trigger listening.
This introduces the "mycroft.stop.handled" messagebus message. It
carries a data field called "by" which identifies who handled it.
Currently the values are "TTS" for when speaking ends or the name
of a skill which implements Stop and returns True from the call.
Also fixed a potential bug when the flag to clear queued visemes
was left set after a button press.
The default method for the services call stop, in the chromecast case this isn't desirable since any playing application would be shutdown (even if mycroft didn't initiate it).
This overrides default behaviour and will merely disconnect from the device at shutdown.
- Engines now specify if they support ssml rather than the configuration
- The text client strips out ssml tags
- Engines can modify tags via the `self.modify_tag` method
This sends a ctrl+c signal to each process which will allow code to exit properly by handling KeyboardInterrupt
Other notable changes:
- create_daemon method used to clean up create daemon threads
- create_echo_function used to reduce code duplication with messagebus
echo functions
- wait_for_exit_signal used to wait for ctrl+c (SIGINT)
- reset_sigint_handler used to ensure SIGINT will raise KeyboardInterrupt
This can be replaced by ensuring the final except clause is 'except Exceptions'. This works because SystemExit and KeyboardInterrupt do not inherit from the base 'Exception' class
* Made MycroftSkill.remove_event() return a bool, preventing unnecessary/misleading message from being posted by MycroftSkill.cancel_scheduled_event()
* More doc and several minor renames around intent processing
* Several minor typo and doc corrections
==== Tech Notes ====
When a new track starts playing the audio service will send a message
indicating which track has started.
==== Protocol Notes ====
"mycroft.audio.service.track_start" message added
The speak method digs through the stack trying to find a Message object
and if found uses the context from that message when sending the data to
the speech subsystem.
==== Tech Notes ====
STT, intent handling, intent fallbacks, skill handlers are now timed and
tied together with a ident (consistent through the chain so the flow from
STT until completion of the skill handler can be follewed.
TTS execution time is also measured, right now this is not tied into the
ident due to the nature of the speech.
The report is always called "timing" and always contain the following
fields:
- id: Identifier grouping the metrics into interactions
- system: Which part (STT, intent service, skill handler, etc)
- start_time: timestamp for when the action started
- time: how long it took to execute the action
The different system adds their own specific information, for example
the intent_service adds the intent_type, i.e. which handler was matched.
==== Protocol Notes ====
mycroft.skills.loaded is sent togheter with skill id and skill name
whenever a skill is loaded. This is used in the intent_service to
convert from id to skill name when reporting
Add Python 2/3 compatibility
==== Tech Notes ====
This allows the main bus, skills and cli to be run in both python 2.7 and
3.5+.
Mainly trivial changes
- syntax for exceptions
- logic for importing correct Queue module
- .iteritems -> future.utils.iteritems when accessing dicts key value
pairs
* Allow audio service to be run in python 3
* Make speech client work with python 3
* Importing of Queue version dependent
* Exception syntax corrected
* Creating sound buffer is version dependant
- Adapt context use range from builtins
- Use compatible next() instead of .next() when walking the skill
directory
* Make CLI Python 3 Compatible
- Use compatible BytesIO instead of StringsIO
- Open files as text instead of binary
- Make sure integer divisions are used
* Make messagebus send compatible
* Fix failing travis
Re-add future 0.16.0
* Make string checks compatible
* basestring doesn't exist in python 3 so it's imported from the "past"
* Fix latest compatibility issues in speech client
- handle urllib
- handle encoding before calling md5
* Make Api.build_json() python 2/3 compatible
the lock could be taken by a waiting thread between sentences in a multi-sentenced utterance. This locking method will allow the entire utterance to be synthezised before handling next.
In code like this:
self.speak_dialog("something")
mycroft.audio.wait_while_speaking()
It was possible that the speaking of "something" would take longer to
start than the 0.1 seconds that was built into the wait_while_speaking().
The definition of this behavior is slightly fuzzy, but this is definitely
a case where the expectation is that previous request for speech would
start and complete. For now, I have just bumped the minimum wait to
0.3 seconds.
In the long run we might consider tracking specific speak requests and
generating a notification when that request has been serviced. Then the
skill could automatically hold off until that request has been serviced.
But the basic skill code won't have to change to make this happen, so
this additional sleep is adequate for today.
Also snuck in a minor change to a comment.
Add support for 'mycroft.mic.listen' on the messagebus to trigger the system
to listen for STT processing. This can be posted on the messagebus by outside
systems, such as a physical or GUI Listen button.
==== Tech Notes ====
queue command will start playback if no playback is running.
mpg123 and vlc services updated support queueing tracks while playing
==== Protocol Notes ====
mycroft.audio.service.queue message added
==== Tech Notes ====
Before the current chromecast application was quit when mycroft was started which caused some interference. Now the current app is quit right before starting playback on the device instead.
==== Tech Notes ====
Previous approach did not work as websocket client was not running, this
uses the standalone send functionality recently added to send a single
message.
The audio service could not handle https URLs. VLC can support them,
so https was added to its supported_uris. Additionally, the play( )
function in the audio service could not actually correctly search the
backends for a supported uri, so the code there has been fixed
This commit officially switches the mycroft-core repository from
GPLv3.0 licensing to Apache 2.0. All dependencies on GPL'ed code
have been removed and we have contacted all previous contributors
with still-existing code in the repository to agree to this change.
Going forward, all contributors will sign a Contributor License
Agreement (CLA) by visiting https://mycroft.ai/cla, then they will
be included in the Mycroft Project's overall Contributor list,
found at: https://github.com/MycroftAI/contributors. This cleanly
protects the project, the contributor and all who use the technology
to build upon.
Futher discussion can be found at this blog post:
https://mycroft.ai/blog/right-license/
This commit also removes all __author__="" from the code. These
lines are painful to maintain and the etiquette surrounding their
maintainence is unclear. Do you remove a name from the list if the
last line of code the wrote gets replaced? Etc. Now all
contributors are publicly acknowledged in the aforementioned repo,
and actual authorship is maintained by Github in a much more
effective and elegant way!
Finally, a few references to "Mycroft AI" were changed to the correct
legal entity name "Mycroft AI Inc."
==== Fixed Issues ====
#403 Update License.md and file headers to Apache 2.0
#400 Update LICENSE.md
==== Documentation Notes ====
Deprecated the ScheduledSkill and ScheduledCRUDSkill classes.
These capabilities have been superceded by the more flexible MycroftSkill
class methods schedule_event(), schedule_repeating_event(), update_event(),
and cancel_event().
==== Tech Notes ====
isSpeaking was lowered as soon a the tts had synthesized the audio and
not when the output finished. This commit moves the signal
raising/lowering to the tts instead of the 'mycroft.speak' handler.
==== Tech Notes ====
pulse_lower_volume() scans through the list of running input sinks and
reduces the volume to 30% of original volume skipping over the stream
named 'mycroft-voice'
pulse_restore_volume() restores the volume again.
If activated with the 'pulseaudio' config parameter they will be called
when mycroft starts/stops listening and starts/stops speaking
==== Environment Notes ====
The Audio->pulseaudio configuration parameter can now be set to 'lower'
to activate this feature
==== Fixed Issues ====
#969

The criteria for excluding messages were inverted and excluded all
messages containing 'mycroft.audio.service'. This criteria has been
fixed.
