<SOLVED> Streaming with MPD and Icecast2

So uh...not sure where to go with this from here.

I'm still here, I've been trying to find a cure for covid-19 as it's easier!
I have set-up a working mpd/mpc on Debian 10 in Virtualbox just by tweaking the original mpd.conf, putting the tracks in /var/mpd/music and chown that directory to mpd:<USER> so it can be done.
I'm also trying to learn FreeBSD in Virtualbox and got it running there too, it was slightly easier as well!
This track is playing in FreeBSD.

What is?

Code: Select all

$ cat /etc/mpd.conf

Code: Select all

$ ls -la /home/radio

and

Code: Select all

$ cat /home/<USER>/mpd/mpd.log

I don't often use mp3 but I think the encoder should be

Code: Select all

encoder     "lame"

Hahaha fair enough!

I'm also trying to learn FreeBSD in Virtualbox and got it running there too, it was slightly easier as well!

I imagine FreeBSD could make a good server. I tried to set it up as a desktop OS on an old netbook I have and it was a nightmare. I gave up.

What is?

Code: Select all

$ cat /etc/mpd.conf

Code: Select all

$ ls -la /home/radio

and

You want the whole /etc/mpd.conf file? It's pretty long. /home/<USER>/ is the same as /home/radio/. Yeah, did I forget to change it in one place? radio is my username and hostname for this box I'm working on. I can tell you ls -la /home/radio/ is /Library and /mpd.

I'm at work right now and just got here, but I will get you the results of cat /etc/mpd.conf and cat /home/radio/mpd/mpd.log when I get home. Also, I will try putting encoder "lame" in my /etc/mpd.conf.

That permission denied error from the 29th about the state file is no longer relevant. I had forgotten to change that in my /etc/mpd.conf file but that has been fixed.

ls -la /home/radio/:

I believe that pid file is the one I created previously. No longer used since I created /home/radio/mpd/pid and changed /etc/mpd.conf to reflect that.

[Dennis99]

I'm sure we are nearly there!
I think we are trying to run as 2 different things which need different setups, I run as a system daemon, you are trying to run a user daemon and that needs the configs in a totally different place.
Thought I would RTFM! From the manual If you run MPD as a user daemon (and not as a system daemon) blah blah blah
https://www.musicpd.org/doc/html/user.html
So as a system daemon, clean up mpd.conf by cleaning up the httpd bit with only the following:

Code: Select all

audio_output {
         type          "httpd"        
         name        "Dead Pirate Radio"
         encoder     "lame"
         port            "8000"
         bitrate         "192"
         tags             "yes"
}

As root:

Code: Select all

# systemctl stop mpd.service

Code: Select all

# systemctl start mpd.service

Exit root

Code: Select all

mpc

Hopefully we get

Code: Select all

$ mpc
volume: n/a   repeat: on    random: on    single: off   consume: off

then try the mpc update mpc ls | mpc add mpc play

As to playlists, I put some songs in the song queue as a test, it's mpc save <filename> to save the playlist, it's saved as a .m3u
eg:
$ cat /mpd/playlists/test.m3u
Kate Bush- Them Heavy People.ogg
Love - Alone Again Or.ogg
etc
Then mpc clear to empty the queue and mpc load <filenam> to load the playlist.

[Huecuva]

I edited my /etc/mpd.conf file to comment out everything but what you said in the audio_output section. Everything else in that file is the same as before. Now:

Code: Select all

audio_output {
#	type		"shout"
#	encoding	"mp3"

I'll worry about playlists after I get it actually streaming. I guess I will actually have to figure out whether httpd or shout is better for icecast2 streaming or if I even need icecast2 to do what I want to do at some point as well.

[Huecuva]

So it appears that in order to set up multiple MPD streams, I do in fact need to use icecast.

I'll just worry about getting one stream working first.

[Dennis99]

No you don't.
You can have a different mpd.conf with a different name with differently named music directory if you want and playlist(s) and differently named tag_cache, log, pid. state and sticker.sql files.
In the new conf, have the same user but a different port (eg 6610) and on the audio output httpd a different port (eg 8002).
Then start the new mpd with

Code: Select all

$ sudo mpd /etc/<newconf>.conf

Then it's

Code: Select all

$ mpc -h 127.0.0.1 -p 6610

Code: Select all

$ mpc -h 127.0.0.1 -p 6610 -w update

Code: Select all

$ mpc -h 127.0.0.1 -p 6610 ls | mpc -h 127.0.0.1 -p 6610 add

Code: Select all

mpc -h 127.0.0.1 -p 6610 play

Where h is the host and p the port.
Just as an aside the original can still be seen on

Code: Select all

$ mpc

or

Code: Select all

$ mpc -h 127.0.0.1 -p 6600[

It will run in tandem with the original, so in theory you could have, say, a top 40 music directory and say a "gold" directory and playlists running together.
The world is your lobster.

[Huecuva]

Ah, well, that's more informative than any of the tutorials or walkthroughs or even the mpd man page or the mpd page on the archlinux wiki, as none of those have been very helpful about how to run more than one instance of mpd. However, how do you set up more than one mpd.conf since mpd will always look in the same location for the mpd.conf file and you can't have more than one file of the same name in the same folder?

I'm still working on getting this first stream working though. It says it failed to enable httpd output and the address is already in use. I think I'm going to try shout and see if I can't get that working. I really don't understand why there aren't more comprehensive tutorials for this.

[Dennis99]

You can have a different mpd.conf with a different name
Then start the new mpd with

Code: Select all

$ sudo mpd /etc/<newconf>.conf

[Huecuva]

Oh, I missed that part of your post. Heh. So then does that make all the different instances of mpd start on boot with their correct .conf files?

[Huecuva]

So I changed the type to "shout" and changed the port to "6600". It didn't complain about being unable to start the type this time but it's still complaining about the port and socket. Here is systemctl status mpd.service:

I don't know what else could be using localhost and I'm not sure how to figure that out. Also, after rebooting it has a whole bunch more complaints. I'll post more about those when I've moved to my other rig to better be able to work on this.

EDIT #1: So after changing type to "shout" mpd had a whole bunch of other complaints. Every time it complained about something I edited /etc/mpd.conf until I ended up with:

Code: Select all

audio_output {
	type		"shout"
	encoding	"mp3"
	encoder		"lame"
#	type		"httpd"
	name		"Dead Pirate Radio"
#	description	"Dead Pirate Radio"
	host		"localhost"
	mount		"/mpd.mp3"
	port		"6700"
	tags		"yes"
#	quality		"5.0"
	bitrate		"192"
	password	"<password>"
#	protocol	"icecast2"
#	device		"hw:0,0"	# optional
#	mixer_type      "hardware"      # optional
#	mixer_device	"default"	# optional
#	mixer_control	"PCM"		# optional
#	mixer_index	"0"		# optional
}

Now it gives me this error. I thought uncommenting encoding "mp3" would fix that but it made no difference at all.

It seems like I may end up having to use Alsa instead of httpd or shout.

[Huecuva]

So after adding a bind_to_address to my audio_output section and changing the port thus:

Code: Select all

audio_output {
#       type            "shout"
#       type            "alsa"
#       encoding        "mp3"
#       encoder         "lame"
        type            "httpd"
        name            "Dead Pirate Radio"
#       description     "Dead Pirate Radio"
        bind_to_address "<MyLANIP>"
#       host            "localhost"
#       mount           "/mpd.mp3"
        port            "8001"
        tags            "yes"
#       quality         "5.0"
        bitrate         "192"
#       password        "<password>"
#       protocol        "icecast2"
#       device          "hw:0,0"        # optional
#       mixer_type      "hardware"      # optional
#       mixer_device    "default"       # optional
#       mixer_control   "PCM"           # optional
#       mixer_index     "0"             # optional
}

and then editing the port forwarding in my router and restarting mpd:

Code: Select all

root@radio:~# systemctl restart mpd
root@radio:~# mpc
Rick Astley - Never Gonna Give You Up.mp3
[paused]  #1/3   0:00/3:32 (0%)

root@radio:~# mpc play

[playing] #1/3   0:00/3:32 (0%)
volume: n/a   repeat: off   random: off   single: off   consume: off

However, going to <MyPublicIP>:8001 still just times out. I don't know if this is some kind of networking issue now or if my streaming just still isn't working.

[Dennis99]

Just for interest, other streamers are available especially into Icecast and I've tried them all:
Ices (ogg only): http://icecast.org/ices/
ezstream: http://icecast.org/ezstream/
butt: https://danielnoethen.de/butt/
Liquidsoap (proably the most complicated but fully featured): https://www.liquidsoap.info/
New talk on Liquidsoap
https://www.youtube.com/watch?v=GmMUuKyy6hY

[Huecuva]

I don't need too many fancy features, so I won't be using Liquidsoap if it's that complicated. Mpd seems simple enough but it seems to be refusing to work so I want to stick to simple. My music is 99.9% mp3 so that rules out ices of that's ogg only. Is ezstream easier to use than mpd? I might give that one a try. At this point I'm really starting to lose patience with mpd.

[Dennis99]

Once you get your head round Liquidsoap, you can get an output for an Icecast server which is what you want with one line!
liquidsoap 'output.icecast(%vorbis,host = "HOST", port = PORT,password = "PASSWORD", mount = "mount.ogg", mksafe(playlist("playlist.txt")))'

where playlist.txt is a list of tracks one per line with the full path /media/usb/The Aurora Principle - Before the Storm.ogg



or change to mp3 by changing 2 things:
liquidsoap 'output.icecast(%mp3,host = "HOST", port = PORT,password = "PASSWORD", mount = "mount.mp3", mksafe(playlist("playlist.txt")))'


You can also normalize and do smart crossfades still on 1 line if you want:
liquidsoap 'output.icecast(%mp3,host = "HOST", port = PORT,password = "PASSWORD", mount = "mount.mp3", mksafe(smart_crossfade(normalize(playlist("playlist.txt")))))'

[Huecuva]

Well, it turns out my stream has been working. I was able to connect to it if I went to my mpd server's LAN IP. It wasn't working on my public IP because the DMZ hadn't been configured correctly. Or rather, it was configured correctly but the modem/gateway was never rebooted.

My stream is all working now. Man, this has been frustrating. I have one mpd stream set up without icecast and soon I plan to get to work setting up the other mpd streams.

I will keep this thread bookmarked though, in case I decide I want to try out Liquidsoap. It does seem pretty interesting. I'm not much interested in having all the fancy features right now but one day I may change my mind.

Thanks for the help, mate. You're a hero.

[Huecuva]

The main issue of this thread is taken care of, so I'm not going to set it back to unsolved, but running more than one instance of mpd is proving more troublesome than you lead me to believe. If this fails to get any attention I'll make a new thread. I've already posted about this on the mpd forum but the one guy who has bothered to respond there seems a wee bit condescending so far so we'll see how well that goes.

I copied my /etc/mpd.conf file and changed the path to the files that needed their own paths, changed the port for the user (now 6601) and output (8002) and the music source directory path as well as the music output port and I'm getting an error:

Code: Select all

root@radio:~# mpd /etc/mpd2.conf
Apr 11 18:12 : exception: Failed to bind to '[::]:6601'
Apr 11 18:12 : exception: nested: Failed to bind socket: Address already in use

The second mpd instance will not start automatically. When I reboot the mpd server, I can log into it and type in mpc and get the status for 6600 which is the first instance and it works but if I type in mpc -h 127.0.0.1 -p 6601 it says connection refused. However, despite the error above, it will work if run manually.

EDIT: After changing the user port of the second mpd to 6700, I get far fewer errors and the errors I do get I still get for the instance of mpd that does work, so clearly that error means nothing. However, the second instance of mpd still will not start on boot. I don't know how to make it start on boot.

[Dennis99]

I bet the condescending blokes name is Max, I think he is the main developer and unless you have the very latest version he's not interested.
The second instance needs you to fiddle about with systemd and I only have a little knowledge of it.
Have a read of https://fedoramagazine.org/systemd-template-unit-files/, I think it's what you need.
