Quick and easy guide for adding music to Emulatonstation on RetroPie. Noob friendly!

@mitu This change in the script (-l 0 instead of -Z) is actually very helpful.
I now have another build with no music in the bgm folder except for the Sony ps1 bootup sound. With this script you hear it only once when booting and then it's all quiet. :-)
It might become my new main build if I get tired of my playlist.

@coldnpale Ok, I got to run a test and this is what seems to work:

Make a .m3u file with the names/paths of the mp3 files:

/home/pi/music/file_start.mp3
/home/pi/music/file2.mp3
/home/pi/music/file3.mp3
...

Run mpg321 with:

mpg321 -l 0 -@ path_to_m3u_file

replacing path_to_m3u_filewith the actual path of the m3u file.

mitu

@bobharris If you only have 1 file, then just running mpg321 /path/to/mp3file would be enough, i.e. no parameters would be needed.

@mitu Ok thanks!

@mitu thanks a lot! I'll check this as soon as I am back home!

I have a couple questions involving this bgm method, would be interested if anyone has any input.

I've been wanting to modify this where it starts a new song after exiting a game, instead of resuming the same song. My current fix was to edit the /opt/retropie/configs/all/runcommand-onend.sh to be the exact same as the autostart.sh in the same folder. This effectively reloads RetroPie every time I exit a game, and while it does give me the intended effect of playing a new song, it is a bit inconvenient with the extra loading time and not resuming from the same place I was in the games menu. Anyone know of a more elegant method?
Does anyone know of a script where you can have a button that sets a different folder for bgm music, as well as some kind of skip button? I have the on/off button enabled in my RetroPie menu thanks to /u/columboscoat over on /r/RetroPie, but these extra options would be fantastic additions to my build. I have a folder for chiptunes and a folder for remixes, would be awesome to be able to switch them on the fly. I've done some research on the ins and outs of mpg123, but it is way over my head.

Thanks in advance.

That easy to do.
modify /opt/retropie/configs/all/runcommand-onstart.sh with pkill mpg123 > /dev/null 2>&1
This terminates mpg123 if you start a ROM

modify /opt/retropie/configs/all/runcommand-onend.sh with mpg123 -Z /media/usb0/BGM/*.mp3 > /dev/null 2>&1 &
The /media/usb... thing represents the path were the mp3 are deployed

Als no problem. Trigger a GPIO event that terminates mpg123 and restarts it with annother folder path. That's a kind of "SKIP" function.
Sadly mpg123 is a bit limited with controls but it's enough imho for a BGM player.

@cyperghost Thank you so much for the quick response! I will try this stuff and report back if I need further assistance.

Hi everyone!!!
I have a problem with this... splash screen won't play over e.s. loading screen! Emulation always starts at splash screen end. I know that the problem is this method cause it doesn't wait without it!
Any help please?
Ps sorry for bad english
Thanks.

coldnpale

It happens for me also like that.. I thought it was supposed to be like this. It's not a big issue but would be nice to save some more time.

cyperghost

Did not see .... I once gatherd some interesting sniplets that can be very usefull for music control.

This script Toggles mpg123 - so if mpg123 ist not running it will be started. If it's running the process will be stopped. If the process is stopped it will be continued!
The other script Plays annother track. This is simple the same procedure as I posted to @Finnbro - It kills the mpg123 process and restarts it with parameter -Z.

Be aware to change pathes to your MP3 or playlist collection.

zerojay

You can use that with the script that allows you to run commands with combinations of button presses to do all that on the fly.

Interesting. Going to try these loops as "music"

@Alturis
I don't want to hijack the thread
So I created a new BG-Music on Retropie - Post your favourites here

Anyone else having this issue? Is it normal or can it be avoied?

Finnbro

The above scripts are helpful, thanks!

I have a problem getting both mp3 and video snaps playing at the same time. Also the in-game sound is gone.
I think the reason is that the audio source is busy playing the audio (mp3) and it can not handle the video snaps and mp3 files simultaneously for some reason.

This also happens when I use your image @dmmarti (Motion Blue V5) with the included background music script. Do you have an idea what I can do?

I'm using a USB Sound Card such as this one https://www.ebay.com/itm/PC-Win7-Mac-Vista-H1-3D-Virtual-Audio-Sound-Card-Adapter-USB-2-0-7-1-Channel-/152624039538

Any thoughts?
Any help or thoughts are much appreciated.

westleigh77

@tmntturtlguy I had the same thought. It's been a year, thought I'd check in to see if anyone's come up with a solution

edwardthehuman

installed this succesfully, but it mutes the game music/sounds entirely when i enter it. any solution?

Brigane

@edwardthehuman

This is kind of the same problem I'm having. Do you use a USB sound card or just HDMI?
