The autorun mode - TheKikGen/MPC-LiveXplore GitHub Wiki

When the MPC binay detects an "autorun.json", it will launch the script configured in the "script" tag with a sh system command.

autorun.json

{
  "value0": {
    "files": [], 
    "scripts": [
      {
        "askQuestion": true, 
        "path": "install-content.sh", 
        "message": "Install content? This will only install on an MPC One.", 
        "noButtonText": "no", 
        "yesButtonText": "yes"
      }
    ]
  }
}

An "autorun.check" file is here for script integrity. If you modify the script, it will not run because of that check.

It looks like a SHA256 key.

The corresponding shell script is the following :

#!/bin/sh

set -eux

if [ ! -x /usr/bin/MPC ]
then
    echo "Looks like this is not an MPC - exiting"
    exit 1
fi

ACVA_VIDPID="09e8:0046"

if [ "`lsusb | grep $ACVA_VIDPID | cut -d ' ' -f 6`" != "$ACVA_VIDPID" ]
then
    echo "Looks like this is not an MPC One - exiting"
    exit 1
fi

systemctl stop inmusic-mpc

function startmpc {
    systemctl start inmusic-mpc
}
trap startmpc EXIT

AUTORUN_DIR=`dirname "$0"`
CONTENT_DIR=/media/acvs-content/Expansions

rm -rf $CONTENT_DIR/*

gunzip --stdout "$AUTORUN_DIR/content/acva-content.tar.gz" | tar -xvf - -C $CONTENT_DIR
