Bug: Copy multiple .mp3 files to mopidy server machin

[szuniverse]

I copied 20 mp3 files to mopidy server
location:
/home/pi/Music
when I try to local scan with this command:
sudo mopidyctl local scan

WARNING Failed local:track:Fekete%20Teve/Fekete%20Teve%20-%20R%C5%91zse-Dalok%20%282011%29/01%20-%20Fekete%20Teve%20-%20Szeptember.mp3: Track shorter than 100ms

But It is a valid mp3 file becuase I can play via terminal:

omxplayer 01\ -\ Fekete\ Teve\ -\ Szeptember.mp3

If I run the sudo mopidyctl local scan several times sometimes mopidy scan is successfuly but mostly not.

Please run the command mopidy deps and provide the last section, from "GStreamer:" and down. This will tell us what MP3 decoding elements you have in your GStreamer installation.

Dupe of #935, or maybe same root cause at least?

[szuniverse]

Yes I think its the same bug

I wonder if this is a similar upstream bug to https://bugzilla.gnome.org/show_bug.cgi?id=762660.

Maybe you could try the following on a couple of files that do/don't scan correctly:

$ gst-launch-1.0 filesrc location=foo.mp3 \
! mpegaudioparse ! fakesink \
num-buffers=2 silent=false -v -m | grep --color -E "duration|preroll|"

... to see if gstreamer is returning the data in an unexpected order, in which case we should file an upstream bug report.

[SeeSpotRun]

Upstream bug filed at https://bugzilla.gnome.org/show_bug.cgi?id=763553

[SeeSpotRun]

Upstream fix applied by the good folks at gstreamer. This should fix #935, #1453, #1474 and #1480.

To benefit from the upstream fix you will either need to compile gstreamer from source (https://cgit.freedesktop.org/gstreamer/gstreamer/) or wait for gstreamer 1.7.91 to be released for your distro.

In the meantime I'll raise a pull request with a workaround for mopidy.

[SeeSpotRun]

@szuniverse: : if you have a chance, could you please test using https://github.com/SeeSpotRun/mopidy/tree/fix/gstreamer_not_pushing_tags_2 to see if this fixes the problem? This branch has a workaround in mopidy/audio/scan.py to address an upstream bug in gstreamer.

Alternatively if you are feeling adventurous you could try compiling gstreamer from git source...

[szuniverse]

Could you help me how can I install this branch? I am using raspberry pi with latest RASPBIAN JESSIE.
and i usually install mopidy with these commands:

https://docs.mopidy.com/en/latest/installation/debian/

[SeeSpotRun]

There are a couple of options but the quick and dirty is just to replace file /usr/lib/python2.7/dist-packages/mopidy/audio/scan.py with the updated version:

$ cp  /usr/lib/python2.7/dist-packages/mopidy/audio/scan.py scan.py.bak
$ wget https://raw.githubusercontent.com/SeeSpotRun/mopidy/fix/gstreamer_not_pushing_tags_2/mopidy/audio/scan.py
$ sudo cp scan.py   /usr/lib/python2.7/dist-packages/mopidy/audio/scan.py

This just makes a backup copy of the original, downloads the new version and then copies it over the original. You may need to install the wget utility first using sudo apt-get install wget
Then restart mopidy.
You can revert using:

$ sudo cp scan.py.bak /usr/lib/python2.7/dist-packages/mopidy/audio/scan.py
