I'm pretty sure that there is nothing wrong with extraction from ogg
files; we have tests for this. But, if most of these files do not
contain artwork and you add an SD card with thousands of songs and run
up the music app, the music app will send hundreds of requests to the
thumbnailer. No problem, the thumbnailer queues them all up and
patiently grinds through them. However, for each file without embedded
artwork, the remote server has to deliver an image. This is slow. So
slow that, in all likelihood, some of those requests will time out in
the app because they will spend more than 30 seconds in the queue before
the thumbnailer even sends the request for the image to the server.
Again, no big deal. The server will reply eventually, and the
thumbnailer will cache the image. But the calling music app may well get
tired of waiting and show you the "no artwork" default image instead.

However, if you scroll around in a song list or the like, as soon as you
move away from a missing thumbnail far enough and scroll back to it, the
app will re-issue the request for the thumbnail. That second request
will be answered instantly because, by now, the thumbnailer will have
the image in the cache and deliver it in about a millisecond.

So, I'm wondering whether what you are seeing is simply due to the fact
that a lot of files are added at once, and it simply takes quite a while
to fetch the thumbnails for all of them?

The other possibility is that, at the time you tried, the remote server
had a problem, in which case we back off and stop asking the server
again for two hours. That's to avoid hammering the network needlessly
and draining the battery.

Title:
  No thumbnails generated for OGG audio

Status in thumbnailer package in Ubuntu:
  New

Bug description:
  Setup:
    Core Music app 
    BQ HD5
    OTA-7 15.04 r6
    Large collection of audio files in .ogg and .mp3 format on SD card
    Audio files tagged with Artist, Album titile, Track title etc.

  Expected result:
    Album covers and Artist images are displayed in Music app

  Actual result:
    Only mp3 audio files generate thumbnails. No Album of Artist thumbnails are generated for any OGG files

  To test the situation I have
  a) Cleared the thumbnailer failure cache
  b) removed the whole thumbnail cache directory
  c) Removed and reinsterted the SD card
  d) Uninstallled and reinstalled the core Music app

  Before the OTA-7 upgrade the thumbnails were shown for .ogg and .mp3
  files
