<SOLVED> Streaming with MPD and Icecast2

[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.

[Huecuva]

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

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.

[Huecuva]

It is indeed Max. Another guy there has responded (before my reply to Max has even been approved) and stated that Max is skeptical of mpd's http streaming capabilities. If he's the main developer, why doesn't he do something about it then? As for what version of mpd I have, I have whatever version is available in the debian repositories, as I just used apt to install it.

Anyway, thanks for the link. I'll have a look through that. I changed some stuff since that post and I figured out I also had to change the bind_to_address for the user. I no longer get that error now. I've also made a third mpd.conf file and while it seems to start manually just fine (also doesn't start on boot but I assume that's for the same reason the second one doesn't and the answer could potentially be found in that link you posted), it throws a completely nonsensical error when I try to connect to it with mpc. mpc -h 0.0.0.0 -p 6700 works just fine on the second instance but mpc -h 0.0.1.0 (or whatever IP I give it) -p 6800 when attempting to connect to the third mpd yields an error: mpd error: invalid argument. It doesn't make any sense.
