added "lastplayed" property for songs

With streaming audio the skins can pick up additional information (such as artist and song name). Is it possible to make that available? Atm all you get is the name of the stream as the label.

With what version of XBMC and the JSON-RPC API did you try this? I added the following commit a while back which should provide more info for non-library items through Player.GetItem: https://github.com/xbmc/xbmc/commit/73fd...32648b3110

This is in Eden. I just tried it in Frodo and get the same. For reference:

Code:

{"jsonrpc": "2.0", "method": "Player.GetItem", "params": { "properties": ["title", "album", "artist", "duration", "thumbnail", "file", "fanart", "streamdetails"], "playerid": 0 }, "id": 1}

Code:

{"id":1,"jsonrpc":"2.0","result":{"item":{"fanart":"special://masterprofile/Thumbnails/Video/Fanart/515043c5.tbn","file":"shout://streamer-dtc-aa01.somafm.com:80/stream/1018","label":"SomaFM Groove Salad","thumbnail":"","title":"","type":"unknown"}}}

Commit: 0bd7924d87f00059a9b4

added SetArtistDetails, SetAlbumDetails and SetSongDetails to the AudioLibrary namespace
added SetMovieDetails, SetTVShowDetails. SetEpisodeDetails and SetMusicVideoDetails to the VideoLibrary namespace
added RemoveMovie, RemoveTVShow, RemoveEpisode and RemoveMusicVideo to the VideoLibrary namespace

I'll update the wiki page on JSON-RPC API v5 ASAP but make sure to take a close look at the JSON schema for the SetFooDetails methods so you don't mess up your (and possibly other people's) libraries Wink

Nice. Fingers crossed for webserver: image transformation handler soon Smile

I'm using Frodo with Firefox and I think the Content-Type change has broken things. It appears that Firefox adds "; charset=UTF-8" to the Content-Type. Bug report. Chrome and IE don't do this and all the JSONRPC requests work fine. Same thing in Firefox gives:

Code:

NetworkError: 415 Unsupported Media Type

from FireBug. Anything you can do on the web server end because Mozilla won't?

Did you get a chance to check on the details of audio web streams whilst I'm here?

jmarshall claimed that PR and will adjust it's implementation so might still be a while.

Should be fixed with https://github.com/xbmc/xbmc/commit/75fd...cb9784be76

As I don't use any audio web streams or similar addons it always takes me a while to look into those things.

That's great, thanks. I don't use them either but Martijn was bugging me Smile

I'm having trouble finding out how the websocket functionality works.
Maybe it lacks documentation because websocket support is pretty new (and maybe unstable), but it would be great if someone could point me in the right direction.

Thusfar I've got the following:

Code:

var xbmcSocket = new WebSocket('ws://localhost:9090/jsonrpc');

xbmcSocket.onopen = function() {

    console.log('xbmcSocket.open');

};

xbmcSocket.onmessage = function(msg) {

    console.log('xbmcSocket.onmessage', msg);

};

So far so good: I now receive XBMC events.

Now I would also like to send commands using the websocket. So my initial though was:

Code:

xbmcSocket.send({

    "id": 1,

    "jsonrpc": "2.0",

    "method": "JSONRPC.Introspect"

});

However, this gives the following parse error:

Code:

{

    "error": {

        "code": -32700,

        "message": "Parse error."

    },

    "id": null,

    "jsonrpc": "2.0"

}

You are probably the first to try and use the new websocket functionality (after me) so first thanks for the feedback. Have you tried other JSON-RPC methods like JSONRPC.Ping etc? I have to admit that JSONRPC.Introspect is a bit of a loose candidate depending on the browser/websocket-implementation is used because of the huge amount of data it returns. During my testing I found out that there are browsers who can handle literally any amount of result data you throw at them while others have a fixed limit (which is pretty stupid considering that WebSocket supports fragmented messages).

Thanks again for the feedback.
