Python Carplay implementation for the "Autobox" dongles. Forked from https://github.com/electric-monk/pycarplay to include audio/video output via mpv and key presses

These are readily available from Amazon, but are also available from cheaper sources. The one I got was labelled "Carlinkit" here: https://www.aliexpress.com/item/32829019768.html
The dongle relies on the copying of various "assets" to the dongle that happens on every boot. To acquire these assets, a script is provided.
Simply run:
./downloadassets.sh
from the repository root.
This script relies on the following packages (installed via apt-get or otherwise):
- ffmpeg
- mpv
- libmpv
- libmpv-dev
The code is intended for Python3. To install the necessary packages, run this command:
pip3 install pyusb
To run, call
sudo python3 carplay.py
(note: you need a user that is allowed to manipulate usb devices, or run as root)
The following keys have been mapped:
- Left - navigate left
- Right - navigate right
- Enter - select active item
- Escape - Go back
- s - Trigger siri. Note: this currently does not work
- p - Pause (if playing something)
- space - resume (if something is paused)
- h - home
- f - toggle fullscreen mode
- e - previous track
- r - next track
Working:
- Audio (for the most part)
- video
- key presses
Not working/implemented
- multi touch - note: electric-monk has an implementation of this in his tesla library. I haven't gotten around to getting it linked up in the mpv player
- Microphone - siri appears to change the audio mode (likely to a lower sampling rate), and my implementation currently doesn't deal with this
- telephone - For the same reason as siri not working
The real 'guts' of this project that drive device communication were not Implemented by me. They were discovered by Colin Monro (Electric-monk). His repo is here: https://github.com/electric-monk/pycarplay
