|Repo:|| XBMC.org (v11)|
|Summary:||Download images and additional info of the currently playing artist|
Addon to download images and additional information from Last.FM and htbackdrops.com of the currently playing artist. The images, along with local artists' images, and info can be used by the skin to create a slideshow for the artist being listened to.
To install this add-on you must do so from the Add-on Manager from within XBMC by going to:
- Get add-ons
- XBMC.org Add-ons
- Program Add-ons
- Artist Slideshow
Version 0.1.0 is the last version available for Dharma. The information below is for version 1.3.1.
- displays slideshow as background for music visualization (must use a compatible skin or update skin using the instructions below)
- option to have artist images downloaded and/or use a local directory of artist images
- option for a fallback slideshow if no local or remote images are found
- option to have a single slideshow displayed regardless of artist playing
- downloads artwork from htbackdrops.com and/or last.fm to display as background for music visualization
- option to download artist bio and other additional information (skin must support display of this information)
- option to download only images larger than a given length and width
- option to download only images with 16:9 aspect ratio
- option to limit size of download cache
- support for internet streams that put the artist name in the XBMC title field (experimental)
- support for other addons using Artist Slideshow to provide the background (experimental)
If you are using the default Confluence skin (or Confluence Vertical), you can download the modified files from here
- local artist images must be on a local drive (mapping a local drive letter or mount point in your OS may allow you to get around this)
- Artist Slideshow shows images behind any running visualization. If you choose to use a visualization, please select one with a significant amount of transparent area or you may not see much of anything.
- On AppleTV the PAPlayer sometimes stops after each song and restarts at the beginning of a new one. That, by default, causes Artist Slideshow to stop. Once that happens, artist background images no longer update. Please see Changes to MusicVisualisation.xml below for a workaround.

5 How to use this addon in your skin
5.1 Changes to MusicVisualisation.xml
To run the script:
On AppleTV if ArtistSlideshow isn't updating after the first artist, use this instead:
To add a multiimage conrol:
<control type="multiimage"> <posx>0</posx> <posy>0</posy> <width>1280</width> <height>720</height> <imagepath background="true">$INFO[Window(Visualisation).Property(ArtistSlideshow)]</imagepath> <aspectratio>keep</aspectratio> <timeperimage>10000</timeperimage> <fadetime>2000</fadetime> <randomize>true</randomize> </control>
5.2 Accessing Script from Other Screens
You might want to use Artist Slideshow to display images somewhere other than on the music visualization. To do that you need to start Artist Slideshow when XBMC starts using DAEMON mode. To do that use:
5.3 New skin properties
This is the path to the directory containing the downloaded images for the currently playing artist
This one is used internally by the script to check if it is already running. There's no need to use this property in your skin.
Artist biography from last.fm
Albums by the artist
6 How to call this addon from another addon
To use this addon to provide the background for another addon, the calling addon must create a window that uses a multimage control:
<control type="multiimage"> <posx>0</posx> <posy>0</posy> <width>1280</width> <height>720</height> <imagepath background="true">$INFO[Window.Property(ArtistSlideshow)]</imagepath> <aspectratio>keep</aspectratio> <timeperimage>10000</timeperimage> <fadetime>2000</fadetime> <randomize>true</randomize> <animation effect="fade" start="0" end="100" time="300">Visible</animation> <animation effect="fade" start="100" end="0" time="300">Hidden</animation> </control>
That window must have an infolabel in which the currently playing artist is stored (suggested name is CURRENTARTIST). It is the responsibility of the calling addon to change that infolabel when the artist changes.
6.1 Additional script/skin properties available
This is the path to the directory containing the downloaded images for the currently playing artist.
Artist biography from last.fm
Albums by the artist
This one is used internally by Artist Slideshow to check if it is already running. There's no need to use this property in the calling addon's skin.
An external addon needs to set this to True so that Artist Slideshow will run properly when called by an external script. This property should be cleared to tell ArtistSlideshow to stop running.
This one is used internally by Artist Slideshow to tell an external script that ArtistSlideshow is done running and is exiting.
6.2 Calling the addon
Artist Slideshow does not exit after being called. It continues to run to check for changes in the artist infolabel. Becasue of that, the calling addon will have to create another thread for Artist Slideshow. The calling addon needs to import the python theading module for this to work.
def runArtistSlideshow(self): #startup artistslideshow xbmcgui.Window(xbmcgui.getCurrentWindowId()).setProperty("ArtistSlideshow.ExternalCall", "True") #assumes addon is using suggested infolabel name of CURRENTARTIST artistslideshow = "RunScript(script.artistslideshow,windowid=%s&artistfield=%s)" % (xbmcgui.getCurrentWindowId(), "CURRENTARTIST") xbmc.executebuiltin(artistslideshow) self.thread = threading.Thread(target=self.runArtistSlideshow) self.thread.setDaemon(True) self.thread.start()
The suggestion is for the addon to spawn this thread right after it spawns the window.
6.3 Exiting the addon
When the calling addon is preparing to exit, it must tell Artist Slideshow to stop and wait until it has. This logic should be added *before* the addon's window is destroyed. Failure to include this step will likely cause XBMC to crash.
#tell ArtistSlideshow to exit xbmcgui.Window(xbmcgui.getCurrentWindowId()).clearProperty("ArtistSlideshow.ExternalCall") #wait until ArtistSlideshow exits while (not xbmcgui.Window(xbmcgui.getCurrentWindowId()).getProperty("ArtistSlideshow.CleanupComplete") == "True"): time.sleep(1)
