From the settings panel of this plugin I can see that performance is a
major concern and I am getting varied result myself when browsing
artists. Sometimes they come in as quickly as you would hope (and I
guess they are retrieved from cache at the time) and sometimes the
server would hang at certain artist images and block for roughly 5-10
seconds or sometimes a placeholder image comes through where previously
an image was returned. The latter only happens in instances where I am
not connected to the internet while browsing, but was connected during
scans.
As DJanGo pointed out make sure you configure the plugin to download the
images and store them locally. I'd even move the image files to a
dedicated folder where you can manually replace mis-matches or poor
images etc.
Is there anything I can do to speed up the artist image retrieval? To
Most importantly: use LMS 7.9. Set the Performance/Memory parameter to
maximum (if you can afford it)
add more context, I am displaying the artist images in my Windows
Universal App and currently I am applying the following resizing to
those images:
http://localhost:9000/imageproxy/mai/artist/4572/image_100x100_f.png. I
am showing them in a list view which fetches roughly 20-30 images at a
time.
Have you tried 100x100_o instead? The problem is most likely that the
first time you want an image, the plugin has to get it. If you don't
pre-cache them, for every image the plugin has to:
- check the music file's folder (and some parent folders, too) for a
local image
- check a potential local cache for the image
- head over to Last.fm to try to find image information for the artist
- fetch the artwork (if found)
- resize the image
- return it to you
As Last.fm would often return URLs for rather large PNG files, the
download of that file alone can take a few seconds!
Now to further speed up your use case you (as a dev) can register your
custom image size you want to have pre-cached. See the "artworkspec" CLI
command. I asked about 100x100_o, as this would by default be pre-cached
for the web UI. If you were using the same, your image cache wouldn't
explode, and the scan wouldn't take longer as with the additional size.
Ideally, I would like all artist images to be retrieved from online
sources only during scans and then stored locally (maybe that is
actually already happening) and only retrieved from local storage. If an
Yes, that's what should happen if configured correctly.
am not using the correct settings. Album images, by the way, come back
from the server very quickly.
Artist artwork should be pretty much the same if pre-cached.
