missionpinball / mpf-mc

The Mission Pinball Framework Media Controller. Controls graphics, sounds, DMDs, and LCD displays in MPF.

Mission Pinball Framework - Media Controller (mpf-mc)

This package is for the "Media Controller" for the Mission Pinball Framework (MPF).

The architecture of MPF breaks the pinball software into two pieces. The core engine which controls the pinball machine and runs the game logic is in the MPF package. Separate from that is the Media Controller which controls the display and sound, including the DMD, Color DMD, RGB LED DMD, and/or onscreen or LCD display. (Note that you need a media controller to drive a DMD and sound even if you don't have an on-screen LCD window. Don't worry--you can run this headless and/or in a console-only environment for those cases.)

This package (mpf-mc) is MPF's "in box" media controller which is based on Kivy and Python. It leverages OpenGL and the GPU of the computer it's running on. There are other media controller projects (at various levels of completeness) you can use with MPF built on Unity, Godot, Rust, and others.

MPF-MC runs on Windows, Mac, Linux, and Raspberry Pi. It can run on the same machine as the core MPF engine, or it can be a separate machine. It runs as a separate process from MPF, so it works well on a multi-core computer.

mpf-mc's Issues

Add audio track control to sound_player (stop, start, pause, resume)

Currently all play/stop control is on an individual sound basis. It will be important to be able to pause and resume all currently playing sounds on a track. For example, when playing a video with embedded audio you may want to pause the music track and don't care what specific sound is playing.

Since the sound_player is based on controlling sound assets, I'm not sure how to add track events (I'd rather not add a track_player). Some additional thought will need to be given to how to expose this functionality in the config files.

Audio locks up after repeated calls to play sfx

Sound player events result in this:
WARNING : kivy : Track: All internal audio events are currently in use, could not play sound sling_bounce

• after triggering the slings multiple times (I assume more than 8 times within the length of the sample)

Seems that sounds only work if ducking: and track: is in the sound player?

Make fonts work from fonts folder in machine folder

Currently fonts have to be installed system fonts

Update travis build script to pull mpf from github, not PyPI

Currently the build script for OS X on travis installs MPF via pip from PyPI, but that's a problem if we update mpf and mpf-mc at the same time since it takes 10-15min for mpf to build and be propagated to PyPI (causing mpf-mc installation to fail).

So we should probably update the script so it just grabs the latest mpf from github instead of installing it from PyPI.

Do we need widget merge_settings?

Why not just use the list of keys in the widget's config before we validate?
If we can do this, that will remove a bunch of lines of code.
If we figure that we do need them, incorporate them into the MPF-side processing of plugin player validation

Sound ducking release not smooth

The release portion of the sound ducking envelope does not transition smoothly back to full volume over the specified duration. Instead the release begins smoothly and then suddenly jumps back to full volume.

Update tests to work with non writable permissions

Tests on Ubuntu 14.04 are failing with permissions errors on mpfcache and high_scores.yaml because it can't write to files/folders in /usr/local/lib...

MPF Unit Tests:
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.4/dist-packages/mpf/tests/machine_files/null/mpfcache'
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.4/dist-packages/mpf/tests/machine_files/high_score/data/high_scores.yaml

From MC Tests:
PermissionError: [Errno 13] Permission denied: '/usr/local/lib/python3.4/dist-packages/mpfmc/tests/machine_files/mpf_plugin_config_player_validation/mpfcache'

This should be fixed for .30 because we tell people to run the unittests to see if their install works.

Add option to automatically load and unload all assets during startup

It would be nice to have a command-line/startup option used to test load all assets in a game (force load and unload no matter the load setting). This could help to ensure that all assets are configured properly and all required codecs/plugins are installed.

When the machine tilts we get warnings in mc

Add Pause and Resume actions to sounds

Add start and stop event notifications for sounds

Add events that are emitted whenever sounds are played/started and stopped, including when a sound finishes playing. The particular events can be specified at the sound asset level or in the sound_player parameters. Could also consider adding automatically generated events such as sound_XXXXX_started and sound_XXXXX_finished, although these should be able to be configured (enabled/disabled on a global and perhaps track level) so we don't flood the event loop and bcp traffic by default.

Create BCP triggers from widget animations

Windowless mode / offscreen frame buffer / no GUI

Need to make it so mpf-mc can run without a GUI, with an off screen frame buffer. This will be useful for DMD and RGB DMD games.

This has been prototyped and works. Just need to get it into the MPF-MC code. Can probably wait until 0.31 since I don't think anyone is using this yet.

Allow plugin players to validate show sections

Currently plugin players can't preprocess player sections from shows, since they run on the mc side but shows run on mpf.

Solution is to extend the functionality of the plugin player config validation so it can validate and update shows too. Will require a slight refactor of the ConfigCollection class so it can be accessed by the part of the plugin player running on mpf

Sounds in playback queue are not removed when stopped

Only sounds that are actively playing are stopped when the sound.stop method is called. Sounds that have been requested for playback, but are queued because the track is busy do not get removed when the sound.stop method is executed. A stop request should also remove a pending sound from the queue.

Add docs to API docs site

Sound markers and related events

Add the ability to specify markers in sound assets that trigger events when they are reached during playback. This would be particularly useful to restart a song at a particular point on the next ball after a ball drains. Markers should be specified at the sound asset level at a particular number of samples or time. Optionally, one or more events to be emitted should be listed under each marker.

Markers should also be able to be used as start points in a sound (optionally provide a marker in the play method).

Add loop until event looping option for sounds

Sounds may be configured to loop indefinitely or a specified number of times (or not at all). There is definitely a need to loop until an event is received (ex: loop a portion of music until the ball is plunged).

Implementation question: when do we start listening for the specified event? Probably as soon as the sound begins playback makes the most sense for now, especially since the entire sound will be looped. If we add more granular loop controls (setup loops within a sound), then the listener will be activated when the loop start point is reached.

python.exe hangs on exit

I don't know if this problem is Windows-only or general, but with mpf-mc, when I hit 'Esc' to close the window, python.exe stays running and I don't get a command prompt. I have to kill python.exe via Task Manager.

I spent about 4 hours troubleshooting and couldn't figure it out. More details here:
http://stackoverflow.com/questions/36563278/sys-exit-not-working-no-other-threads-and-no-try-blocks-capturing-systemexit

It seems to be related to the AssetLoader thread. If I comment that out, everything works fine.

At this point I'm out of ideas, so if anyone else can help, that'd be great. I can post more details if anyone needs them, but I think everything is in the StackOverflow post (which is unanswered at this point).

Need to fix logging

Need to override the kivy logging and use MPF style logs

create character_picker widget

Allow multiple ducking target tracks for sounds

Currently the ducking target parameter for sounds only supports a single value. I'm sure it will be requested to be able to control multiple tracks with a ducking envelope (example: quiet both music and sfx tracks when a voice callout is playing). I don't think it is necessary to have separate envelope settings for each target track so simply making target a list of tracks I believe will be sufficient.

Needs to figure out asset defaults for videos

Currently there's no asset defaults section because we can't read the size of videos, so when videos are found in the videos folder without corresponding video entry, it will crash since there are no defaults.

Worst case have to fix the crash. Ideally we'd figure out some way to pre-set asset defaults, but this might be something that the game developer needs to do.

Add pitch adjustment to sounds

Add ability to adjust the pitch of sounds up or down, including random variations (set max and min values).

changing fps in the config file doesn't seem to work

I added:

mpf-mc:
  fps: 60

Yet the log still reported fps of 30, so need to see if that's a logging issue or it's not being set right or what.

Crash on bad sound ducking settings

The audio interface can crash if bad ducking settings are used. If a release_point setting uses a time that is longer than the sound, a negative start sample position results and causes a crash. Need to add intelligent ducking parameter validation that uses the length of the sound when validating.

Add ability to stop individual instances of sounds

Currently, sounds are stopped by name which means if there are multiple instances of the same sound playing simultaneously they will all be stopped. That may not always be desired. It might be nice to be able to stop individual instances (perhaps by key?).

Exception when running the audio tests

Exception ignored in: 'Pinball.mpf_mc.mpfmc.core.audio.audio_interface.Track._play_sound_on_sound_player'
OverflowError: value too large to convert to int
Exception ignored in: 'Pinball.mpf_mc.mpfmc.core.audio.audio_interface.Track._play_sound_on_sound_player'
OverflowError: value too large to convert to int 

On one of my Lubuntu 14.04 machines. Sound does not play. Works on my other Lubuntu 14.04 machine.

Add docstrings for all event posts

Now that mpf-docs creates its events reference from docstrings in the code, go through all the code and make sure that every event post has a docstring.

Add Physical DMD and RGB DMD

DMD and RGB DMDs need to stream their content to MPF via BCP so they can be displayed on physical DMD devices

Need a warning message for missing video codec

Currently if a video tries to play but Gstreamer doesn't have the codec it needs, the video just fails silently. Would be nice to print a warning about the missing codec.

add expire: setting to slides and widgets

BCP receive thread does not shutdown when main thread crashes

font cropping

need to add settings to trim the tops and bottoms of fonts so they can be aligned properly

Missing Tests

I'll just keep this initial comment up to date with the tests that are needed:

• sound_player " #159
• physical_dmd #160
• physical_rgb_dmd #160

Create entered_chars widget

Need to create the entered_chars widget, which exists in 0.21 and needs to be brought over to 0.30

Implement volume control via BCP
