JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC

Code:

xbmc.executeJSONRPC('{"jsonrpc": "2.0", "method": "Player.Open", "params": {"item": {"playlistid": 2, "position":0}}, "id": 1}' )

The slideshow start with the right picture but other pictures seem to be played in random mode.

Is there a way to play playlist in item order ? Those parameters cannot be used with playlistid ?

Code:

{
          "additionalProperties": false,
          "type": "object",
          "properties": {
            "path": {
              "required": true,
              "type": "string"
            },
            "random": {
              "default": true,
              "type": "boolean"
            },
            "recursive": {
              "default": true,
              "type": "boolean"
            }
          }

These can only be used if all your pictures are in the same directory. IIRC slideshows by default start in random mode so you will need to also pass the "shuffled": false property in the "options" parameter, i.e.:

OK. Thanks for the tip but pictures can be stored in differents directories.

My playlist :
C:\Pictures\Children\Photo1.jpg
C:\Pictures\Holidays\Photo1.jpg
C:\Pictures\Sports\Photo1.jpg

So shuffled is useless ?

"options" parameters is not referenced in documentation ??


http://wiki.xbmc.org/index.php?title=JSO...layer.Open

Ah the "options" parameter is only available in nightly builds (JSON-RPC API v5) and not in Eden (JSON-RPC API v4). If you are targeting Eden then you will need to start the slideshow with Player.Open and afterwards execute Player.UnShuffle.

But I have to say that the slideshow support is rather poor because XBMC's whole slideshow implementation/support is very basic and poor. So JSON-RPC methods in the Player and Playlist namespace may behave differently for slideshows than they do for music and video playback/items.

OK. As my target is Eden Stable, I will keep JSON V4.

SlideShow is basic but I only need to display 10 pictures from a Home widget so everything is OK for me.

Thanks a lot for your answers.

Have a nice and sunny week-end

There seems to be a problem with adding directories that are not in the library:
Works and is in library.
Does not work and is not in library. Invalid params is the error.

Am I missing something?

First of all the first request is wrong, as there's no "type" property in the "item" parameter. The second request you posted looks better but the "playlistid" for picture playlists must be 2 and not 1 (1 is for video), you need to escape the backslashes in your path and the first "id" property in the "item" parameter does not belong there either. So it should look like this:

Code:

xbmc.executeJSONRPC('{ "jsonrpc": "2.0", "method": "Playlist.Add", "params": { "playlistid": 2, "item": { "file": "C:\\Photos\\Leane_20111207_195415.jpg" } }, "id": 1 }')

There is somethind that I don't understand with \ and \\

Pictures path that have to be displayed in slideshow are stored in CommonCache.


So _path is OK and get \\ as _query but get a parse error from JSON :


I have try with :


But same issue

The only way to get slideshow to work is :


It work on Windows but not on Linux :


How can I send the good path to JSON ?

Thanks.

I have no clue about python so I can't really help you there. All I can tell you is that in JSON (and in many (other) programming languages) the backslash \ is used as an escape character so you need to escape it with another backslash. If python uses the backslash as an escape character as well you'll need to escape it again (which is probably why you need the _path.replace("\\", "\\\\")).

Forward slashes / (which are used by linux for paths) don't need to be escaped.

OK.

Thanks.

OK for \ and \\ but I got an other issue with accent

File on my PC :

C:\Photos\Août 2010.jpg

This path is stored on CommonCache and when I request CommonCache, I get UTF-8 String I suppose :


But if I want to add this path to Playlist with this code :


I get an error :


I gess that JSON don't want UTF-8 string as if I call JSON this way :


File is added to Playlist and played.

I've tried many things to encode/decode path from UTF-8 to ASCII or LATIN1 but now I'm lost and I don't know what to do

This is again a python issue. In python unicode strings (as the one you retrieve from CommonCache seems to be) and standard strings are not interchangeable so you have to do the conversion between them manually. xbmc.executeJSONRPC() expects an UTF-8 encoded string and not a "python unicode string" so python complains when you try to put a unicode string into a standard string (even if its UTF-8 encoded).

Maybe you should ask in the addon/script development forum as there are many python addons/scripts that use JSON-RPC, maybe someone can help you there.
