Hi TommyBoy,

try

Code: Select all

redis-cli get act_player_info

on the command line while playing a song.

Code: Select all

root@runeaudio(rw):~# redis-cli get act_player_info
"{\"volume\":\"66\",\"repeat\":\"0\",\"random\":\"0\",\"single\":\"0\",\"consume\":\"0\",\"playlist\":\"6\",\"playlistlength\":\"17\",\"mixrampdb\":\"0.000000\",\"state\":\"play\",\"song\":\"11\",\"songid\":\"12\",\"time\":\"258\",\"elapsed\":\"0\",\"bitrate\":\"320\",\"audio\":\"44100:24:2\",\"nextsong\":\"12\",\"nextsongid\":\"13\",\"OK\":null,\"song_percent\":0,\"audio_sample_rate\":\"44.1\",\"audio_sample_depth\":\"24\",\"audio_channels\":\"Stereo\",\"changed\":\"player\",\"currentartist\":\"3 Doors Down\",\"currentsong\":\"When I'm Gone\",\"currentalbum\":\"iTunes Originals\",\"currentcomposer\":null,\"fileext\":\"mp3\",\"file\":\"NAS\\/Musik\\/Audiophile Stream Network\\/1\\/3 Doors Down - When I'm Gone.mp3\",\"radioname\":null,\"actPlayer\":\"MPD\"}"


You will get all player info as a json encoded string.

thanks so much.
however the numbers dont update ??
i hear the music play, but no time indicators move.. ??

update : if i change volume in the UI, and then ask the command as you suggest in the console
NOW i see changed time info..
can i get updated LIVE values via the console, with out need to touch the UI ?

and one other "thing" the JSON i get looks like yours, but nothing at all like the standards i can read about
here for example
https://en.wikipedia.org/wiki/JSON

[TommyBoy]

No news / solution ?
The UI dont update either, try webradio whete they write the track they play, i need to change volume one up, and then down again, to get an update, same as with this json string,
Just too bad, i had a super idea for a display, but it just will not work, since this stuff is not live.

Hi TommyBoy,

The UI dont update either, try webradio whete they write the track they play, i need to change volume one up, and then down again, to get an update, same as with this json string,

it is the way mpd works. We use the command "idle" to get lowest cpu usage.
You can test this with:

Code: Select all

mpc idleloop

You can poll mpd every few seconds to get "live" data:

Code: Select all

i am sorry, I dont understand a single thing in this answer ?

WHAT exactly do I type in the console, to get that kind og cool info ?

please help ?

[hondagx35]

Hi,

Code: Select all

telnet localhost 6600

and after the answer from MPD

Code: Select all

status

or

Code: Select all

currentsong

See the MPD documentation for more info.

OK it works in the console via putty.
but does it also work, like via a serial line ?
this way I can also access the console, right ?

by the way I dont understand the time, and elapsed in status ?
none of them reveal real length of the track ?
that is in "currentsong" info
but in secs

where do I find all telnet commands for MPD ?

[hondagx35]
