Amazing script, it work like a charm !!!
It's possible to configure buttons for activate and desactivate the script ??? or for configure a fast - rewind audio player ???
It would be amazing !!!!

Just wanted to say i love the BGmusic. works great every time and easy to tweak if need be

Oh boy... this sounds complicated. I was hoping for something a little more "pre packaged" lol. Setting up my raspberry pi with retropie and all my roms was a fun project but i also had google and some great youtube videos holding my hand in the process. Adding music to my pi would be the finishing touch to something i get excited to share with my friends everytime they come over. Ill try my best to wrap my head around this with my university of google.com education. I still hope for someone to simplify this as much as possible. I think a song selection in the emulationstation menu would be a great addition. Much like there is a theme selection built in.

@manser87

for the most part it is,

he does a very good job of explaining what you have to do and how.
Once you get a better handle on how to edit some of the files. this will be easy for you.

it threw me for a loop for a min when the music did not cut for of the Emulators, but then looked and found where i needed to add it

@Livewire Works like a charm, except that it doesn't change to the ingame music when entering a game. The music stops and I have total silence :(

One strange thing is happening to me. For very specific songs, they are played at half speed for whatever reason. These songs include all music I tested from the Mario Kart 8 soundtrack, and the Melee 2 theme from Smash Bros for Wii U. I tried opening the song in Audacity and re-exporting them as mp3/ogg, and both attempts changed nothing.

Anyone has an idea what is going on?

manser87

I did it!!! I'm so freaking excited! Thanks for this!

I've added "smw","supertux","cavestory" to my emulatornames= line, but only Cave Story is recognized. I suspect it's because it's a Retroarch core (lr-nxengine), rather than a standalone binary.

Do I have the wrong process names for Super Mario War and Super Tux?

Edit: I had everything right, I just needed to restart the Pi.

@felleg dont know if this will fix it, but does any of the song have anything in the ID3 tags? if they do they clear them out.

i had a problem with the Doom port seeing my MP3s before i cleared all the tag info.

i dont know if it will help or not, just a thought

It's worth a shot, I'll try it out and edit this post with the result when I get home.

I can confirm that this code works like a charm!

The only thing I would mention, being a new Raspberry Pi user, is that i had no idea how to create the .py file. It turned out that I needed to download python and pygame for PC, copy the text script in, and then save the file, then move it to the pi and make sure it was in the correct folder! ugh!. Good fun though.

Big shout to livewire for making this. I too, though am having the same issue with some MP3's playing at half speed, any fix for this would be great.

All in all, fantastic to have background music on my retropie.

Great work!!!!!

Sometimes the music is still playing when a game is already running.

I've tested lr-mame2003 with arkanoid and the music stops in the check ram screen...

I have launching.png screen too...

How can I stop it sooner? I'm changing values in the volumefadespeed (from 0.02 to 6.0) and sometimes there is a little difference.

Thanks again.

I think i may have figured out why some mp3 files will play at slower speed.

When the PyGame mixer is intialized using the default settings

pygame.mixer.init()
initialize the mixer module
init(frequency=22050, size=-16, channels=2, buffer=4096) -> None

So i suppose the mp3 files HAVE to be this format to play correctly, now i downloaded most of the music I am using and some files play at the correct speed and some play slower, so what I will do tonight is look at the information of the files and check to make sure they are the same.

Once i have checked this I will update.

Would anyone be able to conifrm or deny if this could make a difference?

Thanks

felleg

@retrobean Nice find! I'm excited to see the results :)

retrobean

@felleg I shall report back when i've had a chance to look into it :D

@retrobean Not to derail the thread or take away from @Livewire's contribution here, but you can also just use an external mp3 player such as mpg123 to play music without worrying about details.

install mpg123

sudo apt-get install mpg123

edit /opt/retropie/configs/all/autostart.sh and before emulationstation is called;

while pgrep omxplayer >/dev/null; do sleep 1; done
mpg123 -Z /home/pi/bgm/*.mp3 >/dev/null 2>&1 &

edit /opt/retropie/configs/all/runcommand-onstart.sh

pkill -STOP mpg123

edit /opt/retropie/configs/all/runcommand-onend.sh

pkill -CONT mpg123

edit /home/pi/.bashrc and add

[[ $(tty) == "/dev/tty1" ]] && pkill mpg123

This will randomly play mp3s from the specified folder (step 2), pause the player upon entering a game, resume when exiting, and also stop the player when exiting emulationstation and dropping to a bash shell.

retrobean

@synack nice! this looks like its worth doing.

Thanks.

retrobean

@synack

just added the code in now! fantastic works well first time.

Thanks for that.

Emulatiosstation with bgm is go go go!!

josete2k

Does mpg123 also work with ogg files?
