Launchcontrol (Alpha)

Launchcontrol is a server that can control a Launch. This project contains plugins for both Kodi and VLC to communicate with the Launchcontrol server (loading scripts, pausing playback, etc.)

Currently only Kiiroo scripts work, but the goal is to support multiple haptic protocols/formats.

Launchcontrol is made for Linux but should also work on a Mac. Works great on a Raspberry Pi with LibreELEC using the Kodi addon.

The Kodi and VLC addons should work on all platforms (Linux, Mac and Windows.)

Requires a Launch with (at least) firmware 1.2.

Build

go get ./...
go build
sudo setcap 'cap_net_raw,cap_net_admin=eip' ./launchcontrol

Usage

# Start server (listening on localhost:6969 by default)
./launchcontrol

# Load and play script
curl -XPOST --data-ascii "{0.50:1,1.00:4,1.15:0,2.00:2}" \
	http://localhost:6969/v1/play
# Pause a playing script
curl http://localhost:6969/v1/pause
# Resume paused script
curl http://localhost:6969/v1/resume
# Jump to a position in the script
curl http://localhost:6969/v1/skip\?p=1m3s
# Stop and reset script
curl http://localhost:6969/v1/stop
# Start playing last loaded script
curl http://localhost:6969/v1/play

Kodi Integration

The Launchcontrol Kodi service addon connects to a local Launchserver and auto loads scripts and synchronizes playback, taking into account actions like pausing and seeking.

Scripts that are paired with the movie file will be loaded. Pairing is done by placing a script file next a movie using the same base filename (this mirrors the same convention as for nfo or artwork). The addon uses Kodi's VFS while searching and loading scripts, so even movies on remote sources like SMB or HTTP servers will work.

Movie/script pairing example:

• /my movies/title.mp4
• /my movies/title.kiiroo

Install

Download script.service.launchcontrol.zip from the releases page. Or package the plugin yourself from contrib/kodi/script.service.launchcontrol. Just zip up the directory (or use the Makefile.)

This guide shows how to install the zip file in Kodi. After installation the plugin will automatically start.

NOTE: If you are running Launchcontrol on another machine then Kodi or are not using the default port, the address can be changed in the add-ons configure menu.

VLC Integration

VLC extension for Launchcontrol loads script from the local machine into a Launchcontrol server and plays them in sync with a video. Pairing works the same as for the Kodi addon, just place the script file next to the video using the same base filename.

Note: The VLC extension has less features then the Kodi addon, see VLC Extension README for details on what's included.

Install

Place the launchcontrol.lua in VLC's lua/extensions/ directory and reload extensions or restart VLC. The extension must be enabled every time VLC is restarted by clicking view -> Launchcontrol. See VLC Extension README for more details on the extension.

Raspberry Pi v2/v3 with LibreELEC

Make sure Bluetooth is disabled in the LibreELEC Services tab.

Build Launchserver for arm:

go get ./...
GOARCH=arm GOARM=7 go build

Build the script addon:

make -C contrib/kodi/

Note: Pre-build binaries are also available on the releases page.

Copy the build results and an autostart.sh to the Raspberry Pi:

ssh root@libreelec 'mkdir /storage/launchcontrol'
scp launchcontrol root@libreelec:/storage/launchcontrol/
scp contrib/kodi/autostart.sh root@libreelec:/storage/.config/
scp contrib/kodi/script.service.launchcontrol.zip root@libreelec:/storage/

Reboot LibreELEC and install the script.service.launchcontrol.zip addon.

Thats it!

Bluetooth requirements

See the gatt docs for the Bluetooth requirements/setup.

Other examples

Build and run example (Linux)

go build contrib/examples/playkiiroo.go
sudo setcap 'cap_net_raw,cap_net_admin=eip' ./playkiiroo
./playkiiroo -file input.txt
