[HOW-TO] Spotify Connect Web for Moode

[TheOldPresbyope]

Hi. During long listening spotify the cache size (/var/local/www/spotify_cache/files) increases and takes up all the free space on the memory card, because of this, the system stops working stably, is there any solution to limit the cache size ? I try to clean this folder on my own through cron, it looks like it works.

P.S. Moode 4.3 (with native Spotify support)

Looking through the issues log on the librespot github repo, I see that this same problem was addressed by the maintainer last year with the addition of a new run-time option "--disable-audio-cache". It isn't clear, at least to me, what side effects this option may have so we'll likely have to test it before adding it in moOde.

I make the change to playerlib.php and have been listening to Spotify tracks for the past three hours. So far it seems to be working for me. I can't say this is an exhaustive test but it is at least a proof of concept. With the change and a reboot there is no caching of files to /var/local/www/spotify_cache/files directory. I cleared it once and it remains empty.

You apparently listen to Spotify a lot more than I do so how about testing this change too to see if I've overlooked a side effect? Since you have been mucking with cron I'm confident you can deal with the edit involved. 

In /var/www/inc/playerlib.php, there's a long string-concatenation statement beginning at line 1752 (in moOde r43)

Code:

    $cmd = 'librespot' .
        ' --name "' . $_SESSION['spotifyname'] . '"' .
        ' --bitrate ' . $cfg_spotify['bitrate'] .
        ' --initial-volume ' . $cfg_spotify['initial_volume'] .
        $linear_volume .
        $volume_normalization .
        ' --cache /var/local/www/spotify_cache --backend alsa --device "' . $device . '"' .
        ' --onevent /var/local/www/commandw/spotevent.sh' .
        ' > /dev/null 2>&1 &';

Insert a new line "' --disable-audio-cache' ." so the statement reads something like

Code:

       $cmd = 'librespot' .
               ' --name "' . $_SESSION['spotifyname'] . '"' .
               ' --bitrate ' . $cfg_spotify['bitrate'] .
               ' --initial-volume ' . $cfg_spotify['initial_volume'] .
               $linear_volume .
               $volume_normalization .
               ' --disable-audio-cache' .
               ' --cache /var/local/www/spotify_cache --backend alsa --device "' . $device . '"' .
               ' --onevent /var/local/www/commandw/spotevent.sh' .
               ' > /dev/null 2>&1 &';

and reboot (executing "sudo /home/pi/srestart.sh" might be enough).

Listen to the music.
