Last.Fm scrobbling support

[abhijeet]

First of all, I love this software. It has unlocked the potential of my PS3 beyond my wildest dreams.

One feature that would make me abandon every other media player I use would be Last.fm scrobbling support. I really like the sound quality that the PS3 optical output provides. With support for scrobbling, I can stop using other media players altogether.

The server also does a great job of transcoding audio and reading metadata from audio files. My thanks for that too

I second that

It would be nice but only if you could do playlists somehow I think.

Using version 1.04, I can see all my m3u playlist files in the menus and they work fine too.

full agree! scrobbling would be a great feature

Hi Everyone!
The last weeks I started to code a experimental last.fm support for pms. I used this library http://code.google.com/p/lastfm-java/, which is pure java, so there were no problems including it.
This is what is working so far:

-Scrobble all audio files with pms including "Now-Playing" feature
-View last.fm weekly and overall charts through folders in medialibrary
-Basic support for playing radio (including scrobble)
-Basic configuration gui

If any of the devs wants to include this in the pms sourcecode I can send an email with the (patched) "lastfm.java.jar" and the patch to the pms source.

very interesting
how did you proceed ? to plug a module with sound output isn't so easy with the massive doc and comments left in the project (mode irony on )

[Phate666]

I didnt write a new module, I just added some code in DLNAResource.java method "public InputStream getInputStream(...)" before

Code: Select all

externalProcess = player.launchTranscode(getSystemName(), media, params);

to "start" the scrobble process (Basicly just saves the time when play starts and the mediainfo of the track). To notice when the track has finished playing I added code to ProcessWrapperImpl.java.

Code: Select all

well, with this, it seems you are playing last.fm on the computer, not the ps3 ?

[Phate666]

You can either play audio files from your pc normaly on your ps3 and what you play is sent to http://www.last.fm/, or you can play for example the "Recommends radio" from last.fm, which is a normal mp3-internet-stream.
