MPD and USB sound card

[fvdw]

attached some archives. I assume you are experienced linux user so I limit the instructions ;) and I assume you know how to use mpd and mpc

(1) mpd-root-adapt-13feb18.tar
This needs to be unpacked in the root of the system partition
For exmaple put it in the shared folder fvdw, connect with putty and give commands

Code: Select all

mv /direct-usb/fvdw/mpd-root-adapt-13feb18.tar /mpd-root-adapt-13feb18.tar
tar -xvf /mpd-root-adapt-13feb18.tar

(2) addon-alsa-mpd-mpc-13feb18.tar
This one needs to be unpack in the fvdw-addons directory (do not untar via samba server)
Put the tar archive in this fvdw/addons folders (fvdw is is a shared folder aleady defined if correct, addons is a subfolder of this shared folder)
Unpack by connecting via putty and give command

Code: Select all

cd /direct-usb/fvdw/addons

file removed need to add mpd.conf


tar -xvf addon-alsa-mpd-mpc-13feb18.tar

Furthermore you need to create a shared folder with name "mpd" using the web interface
In that shared folder create a folder with name "playlists"

You also must created a share with name "muziek" as I added a config file for mpd using that one as folder containing all music.
Of course you can cahnge that by adapting the config file, the config mpd.conf file is in /usr/local/etc (=/direct/usb/fvdw/addons/etc)

currently this is the content of mpd.conf

Code: Select all

bind_to_address "127.0.0.1"

audio_output {
  type "alsa"
  name "USB audio card"
  device "hw:0"
  mixer_control "Speaker" 
}

#neighbors {
#    plugin "smbclient"
#}

input {
    plugin "curl"
    proxy "proxy.local"
}

filter {
    plugin "volume"
    name "software volume"
}
database {
    path "/direct-usb/mpd/database"
}
music_directory "/direct-usb/muziek/"
playlist_directory "/direct-usb/mpd/playlists"
pid_file "/direct-usb/mpd/pid"
log_file "/direct-usb/mpd/mpd.log"



This version of mpd has support for wav, mp3 and flac (and some more) and also has support to be accessed by upnp client. The package includes alsa and mpc (mpd command line client) and all required extra libs

---Jocko edit feb 25th---
Removed the package: mpd-root-adapt-13feb18.tar as it overwrites some changes provided by the rollup patch_05 and later for version 17.0.
This rollup patch_05 includes the required updates on the firmware file system

[lexam]

I'm still testing, but it works according to the instructions, it's recognized by the python client I intend to use it with and plays music fine. One thing that I'd like to ask you is if it would be possible to include support for ffmpeg decoder, as I can't seem to have it play radio stations and/or google TTS.

Thanks again for all your support and hard work!

[fvdw]

Yes this could be done. The firmware has already the related libs on board but this version of mpd needs a more recent version than those installed. I need to check if upgrading them will affect other applications. So you need to have some patience ;)

[fvdw]

I compiled the latest version of ffmpeg, but it is too big for the firmware image due to the many decoders, encoders, muxers, demuxers.\
Which one do you miss in the current alsa/mpd pacakage to enable radio streams or google TTS ?
If I know that I can disable all the others we won't need to make size acceptable.
For instance trancoding of audio or video is not an option on a nwsp2 (cpu not powerfull enough and ram not suffcient)
So in principle all encoders could be disabled

I doubt if mpd need them all, based on the current firmware and alsa setup this is mpd configuration (+) is supported (-) not

I managed to make a version with a new version of ffmpeg installed as addon along the one in the firmware and let mpd use that one :mrgreen:

[lexam]

Hi,

sorry I did not respond to your previous question, I was quite busy with work. This is great, I'll test it out as soon as you make it available for me to download.

Thanks again

[Jocko]

Hi lexam,

I'll test it out as soon as you make it available for me to download.

fvdw waits information from you about the required codecs to post the new files

which of the not yet supported decoders (file format) would you need ?

There is a size issue with the last version

[fvdw]

Yes I was waiting on information from lexam, :tapfoot :disapprove ;) but because he took his time I tried to make a package that contains a new ffmpeg version (the most recent one!!) as addon along the existing on in the firmware and forcing mpd to use that. Pretty cool isn't it :vhcool
Seems I succeeded in doing that, learned again some tricks along the line
PS mpd has a huge dependency list, see below, so its not so easy to set the compiler up. But you can see it now uses the ffmpeg libs (libavxx) in /usr/local/lib and also the ffmpeg binaries do this. :ugeek:
