Mopidy-Touchscreen


#1

mopidy looks pretty cool. i have used MPD quite a bit and now im trying to get my new raspberry pi 3 with adafruit 2.8" capacitive touch screen working. it has taken me a few days to get things figured out, to get mopidy running and grabbing my local tracks, to get the spotify extension working. i used adafruits easy install image so the touchscreen works and not only do i see console output but the touchscreen test program shows touch inputs working. Mopidy-Touchscreen installed fine and it says its running when i run mopidy (sudo mopidy). i have added root to the audio group and spotify and my local files play fine. unfortunately i dont quite understand how and where i can access the actual touchscreen interface. my pi just shows the INFO lines from mopidy that its running and the extensions are loaded. am i missing something?


#2

ok. i figured it out. i didnt have the lines needed in the mopidy.conf file:

sdl_fbdev = /dev/fb1
sdl_mousdrv = TSLIB
sdl_mousedev = /dev/input/touchscreen

once i did that, presto change-o… it worked! i was having problems with the mouse pointer being stuck in the upper left corner. the touchscreen would work, it only registered a click in the upper left corner though. so i followed thse instructions to use the old SDL library https://learn.adafruit.com/adafruit-2-8-pitft-capacitive-touch/pitft-pygame-tips and that fixed the remaining problems. the only issue i still have is no album art for my local files although it is pulling art for the spotify songs. any ideas? anyone?


#3

this is what i am getting on my Now Playing screen even after i installed Mopidy-Local-Images (it is playing music right now)


#4

That screen should show some controls on the top (Volume, pause…). Probably an error happened and because of that nothing is being shown on that screen. I only use Spotify and I made and tested the code to work with it, so probably some adjustments will need to be made to work with Mopidy-Local-Images.

You can run mopidy using the next commad:
sudo mopidy > log.txt 2>&1
This will save the output to log.txt. Check for errors on the file or post it here so I can check what is going wrong.

@9and3r thanks for taking a look and thanks for writing that cool touchscreen plugin. heres the log. i started mopidy, selected local files, selected a file and then pressed the NowPlaying tab and it was red with no title.

The problem is that the song has no defined duration and because of that mopidy-touchscreen crashes as it expects to get the duration. This error should be already fixed on the development version.
Install mopidy-touchscreen from github (develop branch) and it should work.


#7

thank you. i installed with pip install mopidy-touchscreen. how do i install the development version? download the git and copy the script files over the old ones?


#8

i installed it by running the setup.py in the git package. i am still getting the same error

EDIT: sorry. i made a mistake and it was the old version i was installing. once i figured out to download the DEVELOP zip and install that one, the error went away. i am still working on getting local images to work from my MP3 files, does your module require the Mopidy-Local-Images to pull images? where does it get the artwork?


#10

@9and3r hey i have figured something out. if i play local media through a playlist that i created with mpd/mpc:

mpc clear
mpc -w update
mpc listall | mpc add
mpc save allmusic

and then through mopidy i select the playlsit, Mopidy-Touchscreen has the title of the song but says Unknown Artist and Unknown Title and has no playing time. if i play the SAME song through the local media tab, it has playing time and artist and album. i am still NOT seeing album art from local files so my question above is still relevant.

as far as i can tell, the playlist is the only way to play ALL my local music on random. so this is what is holding me back from actually using Mopidy and Mopidy-Spotify and Mopidy-Touchscreen as my main system. any ideas?


#11

@9and3r - is Mopidy-Touchscreen working with Raspberry Pi Stretch?
pip install Mopidy-Touchscreen outputs the following error:
