Play an MP3 from a C++ program

[debazthed]

Hello everyone,

I am looking for a way to play an mp3 file from a c++ program.

The only thing I found is mpg123's api, which I could not make much sense of. Does it even play files or is it just a decoder?

Any suggestions?

Kind Regards

This isn't really a Pi question. I typed in "C++ mp3 playback" into Google and got endless answers. You can do it.

you may also want to look at "hello_video" with a little work maybe you could modify it to work with mp3. i dunno if the hardware decodes mp3(in hardware)

I would recommend you to try and play an Ogg Vorbis files instead.

Besides being a free format and having a better quality-to-bitrate ratio, it's really easy to do so if you follow the examples online, and it looks like more platform-friendly than FMOD. (Although I've never used fmod.)

Hi,

This is an excellent little C program which plays MP3 music files from the command line (no X gui)...

I also tried his Play URL version which also worked a treat...I just found a local radio station broadcasting in MP3 format (not BBC unfortunately) and hey presto! - turned my Pi into a digital internet radio

Don't forget to install the libmpg123 and libao libraries first before trying to compile it...

sudo apt-get install libmpg123-dev
sudo apt-get install libao-dev

Hope this helps,

Yes it does. Thank you.

I replaced my door-bell (and this old style AC/AC powersupply) with this. The doorbell-switch pulls an I/O-pin over 100kOhm to 3.3V and activates a doorbell-sound.
I will replace this with a optocoupler, because of the long wire to the push button which is at the gate.
