Modified Background Music Script with added overlays!

@legacy make sure your rc.local file looks like this example one: https://pastebin.com/67BnuB17
Also can you run the python script from SSH and tell me what it outputs?

@madmodder123

The command works with no problems. Also my RC file data looks ok. I'll upload it for you soon. Also i am using dev version of emulation station.

Thank you.

#!/bin/sh -e

rc.local

This script is executed at the end of each multiuser runlevel.

Make sure that the script will "exit 0" on success or any other

value on error.

In order to enable or disable this script just change the execution

bits.

By default this script does nothing.

Print the IP address

_IP=$(hostname -I) || true
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
(sudo python /home/pi/BGM.py) &
exit 0

I know this is a very stupid noob question but here goes anyhow: when you say in the instructions to “move” the shell script file to the pi, what directory do you move it to- or is it outside of any of the default directories by itself? I would use samba to move it over on windows to the pi and want to make sure I move it to the right place before following the directions above. Thank you! Looking forward to trying this!

madmodder123

@bjretro Move it anywhere on the Pi, it doesn't matter what directory. But "/home/pi" is the easiest.
If you move it somewhere else then you would have to run "cd /home/pi/whateverdirectory/" before running the next commands :)
Then "sudo chmod +x BGM_Install.sh" to make it executable.
Make sure you run the script as root using "sudo ./BGM_Install.sh"

If imagemagick or pygame aren't installing run "sudo apt-get update" (ALWAYS MAKE A BACKUP OF YOUR IMAGE BEFORE ANY UPDATES!) and then run the script again :)

BJRetro

Thank you I will give it a try!

Can anyone test the script on the dev version of emulation station.

For some reason on my build the script will not run at boot and im not prepared to rebuild my retropie image as it take ages and works perfect. Clean install may fix the issue.

As ive said I have no loading screens on boot and the emulation station logo disabled so it boots straight into the front end, mainly for an arcade cabinet, no text no nothing.

Something is blocking the RC.local file from running. So it would be a shame to abandon this script for now.

update error:

Warning: rc.local.service changed on disk. Run 'systemctl daemon-reload' to relo ad units.
Job for rc-local.service failed because the control process exited with error co de.
See "systemctl status rc-local.service" and "journalctl -xe" for details.

I wonder why everyone wants to edit these poor creatures rc.local. There is an explicite autostart.sh (edit with: nano /opt/retropie/configs/all/autostart.sh) and then write sudo python /home/pi/BGM.py & BEFORE starting EmulationStation ;)

@madmodder123 Do we really need sudo command? For rc.local it is obsolete anyway....

legacy

@cyperghost , you have hit the nail on the head.

Its working fine, only issue i have is the

/usr/local/bin/pngview : no process found.

any idea on how to fix this. Thank you

cyperghost

@legacy type ls /usr/local/bin/pngview is the file available?
If yes type sudo chmod +x /usr/local/bin/pngview

If no type cd /usr/local/bin
then type sudo wget "http://raw.githubusercontent.com/madmodder/retropie_music_overlay/master/pngview"; sudo chmod +x pngview

legacy

@cyberghost,

awesome work. Its working now. Thank you.

I have one small problem and maybe you can help.

Im using video loading screens, so the music fades out and then when the loading screen ends the music kicks back in for 1 second then stops and loads my game. Can this be fixed. It must be in the BGM.py file

Update:

on reboot: /usr/local/bin/pngview: process error returns

legacy

On video loading screens, the volume fades, then at the end of the screen, the music plays again and fades and then loads the game.

legacy

@madmodder123,

I click a game, the video loading screen kicks in and the music fades out.
Black screen appears to load the game, but the music kicks in for 1 second and fades out, then the game loads.

is there a fix for this. Thank you

DarishZone

Hello madmodder123, your script is great, love how music fades when snap video audio starts, and overlays are ace, however there's a fix to prevent them to show on terminal or Retropie dos-like menu (Retropie setup for example) ? It may interfere with text.

darknior

@DarishZone for my part i launch it with autostart.sh
And i add python /home/pi/scripts/BGM.py 2>&1 1>/dev/null &
The printf are not writing in console, but some time like you it write on some setup menu i don't know why :(

I will try this! In that case i have to remove the line added on rc.local file?
I also wonder if there's a way to move track names overlays to upper right screen instead of left, seems a more convenient position.

Yes you are, it is explained. You can't use the two files.

I also wonder if there's a way to move track names overlays to upper right screen instead of left, seems a more convenient position.

Not for me, but all of this is on the script, you must modify it by yourself. It is explain on git.

Thank you, but not seems to work for me, can you show me excatly the complete line on autostart.sh?

Edit: managed to move overlay, but now terminal report me an error (?)
/usr/local/bin/pngview: no process found

Is that normal? I'm afraid it was always there and overlay covered it.

Edit 2: I've found edit autostart.sh to run script instead of rc.local trigger that message

DarishZone

Even with local edit, systemlog often report /usr/local/bin/pngview: no process found, and also terminal triggered it if i disable bgm music, also on terminal i can see some strange icons like "[["
Also, it's rare but could happen system hangs at boot, before splashscreen starts, it left with only blinking cursor on top left of screen, not sure if that one is related to my setting (probably)
Any advice?

wmarcio

This script dont work on Lubuntu 18.4 x64 (Retropie install) on a DELL 3020m.
Its say something about tvservice. U can help US?

Thxs for your great work.

mitu

@wmarcio tvservice is specific to the Raspberry Pi installation, used to determine the current screen size. You should modify the Python script to use another method (xrandr comes to mind) and it should work.
