can't find it in the API reference. Is here a way to direct switch to a TV channel (PVR) using a json command?
Player.Open can take a "channelid" property in the "item" parameter.
Apologies as I'm a beginner here, what would be the correct format for the call via http, I tried this and it failed:
http://192.168.1.148:8080/jsonrpc?request={%22jsonrpc%22:%20%222.0%22,%20%22id%22:%20709,%20%22method%22:%20%22Player.Open%22}
with this
{"error":{"code":-32602,"message":"Invalid params."},"id":709,"jsonrpc":"2.0"}
so i messed my parameters up but where?
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Montellese - 2013-09-05
First of all there seems to be an invalid character in your URL. Furthermore you didn't pass in any parameters at all. You just call Player.Open with no additional information.
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Milhouse - 2013-09-15
Just an FYI but the latest Gotham master build from git (on a Raspberry Pi, OpenELEC) results in an unhandled exception when calling "VideoLibrary.GetSeasons":
Code:
21:33:59 T:2860594256 ERROR: Action - thread TCPServer, Unhandled exception caught in thread process, aborting. auto delete: 0The precise call (over TCP) is:
Code:
{"jsonrpc": "2.0", "params": {"sort": {"order": "ascending", "method": "season"}, "tvshowid": 169, "properties": ["season", "art"]}, "method": "VideoLibrary.GetSeasons", "id": "libSeasons"}RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Montellese - 2013-09-15
Tried it on my win32 dev machine with several different tvshowid's and didn't see any problems. Any chance to get the exception or stack trace? Can you try the same request without the sorting and/or without the properties to check if one of those is the culprit?
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Milhouse - 2013-09-15
There is no stack trace (at least not in xbmc.log - is it written elsewhere?)
Without sorting (but with those same properties), it works fine - no exception.
With sorting, but without properties, it causes an unhandled exception.
So it looks like sorting is the culprit (descending also causes the exception).
It doesn't appear to be specific to any particular tv show, it's the same with every show I have tried. Oh, and I'm using MySQL in case that makes a difference.
This is what I see in xbmc.log with debug enabled:
Code:
22:40:27 T:2861126736 DEBUG: JSONRPC: Incoming request: {"jsonrpc": "2.0", "params": {"sort": {"order": "ascending", "method": "season"}, "tvshowid": 169}, "method": "VideoLibrary.GetSeasons", "id": "libSeasons"}

@Montellese: I've tracked it down to a new performance patch - my bad, should have mentioned I was using additional patches but thought they were "safe". In hindsight, I've no idea why I thought that...
The patch that causes the problem is this one, which is the second of a pair of patches, the first of the pair being this patch which by itself isn't a problem - it's only when both patches are applied that the problem occurs (the second patch won't apply without the first).
I've notified the author of the patches about this clash with JSON and "VideoLibrary.GetSeasons". I don't understand the reason, just that with this "step 2" patch the exception occurs, and without this patch JSON behaves normally. Maybe the JSON code has a dependency on the updated sort methods.
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Montellese - 2013-09-16
It's probably not even JSON related, it just crashes in the TCP server thread because that's where the JSON-RPC request is executed and therefore also where the sorting is executed. Have you tried playing around with the sort order for seasons in the GUI?
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Milhouse - 2013-09-16
Fair point, however changing the order of Seasons in the GUI works without a problem (I can also change the order of TV Shows, and Episodes via the GUI). So far the only problem I can find is via JSON RPC (not saying it is the problem, just that's where I see it...)
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - mikebzh44 - 2013-09-16
Hi.
Is it possible with a simple JSON query to get season poster (and season art) for an episode ?
Thanks.
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - mikebzh44 - 2013-09-25
Not possible
?
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - mikebzh44 - 2013-09-25
Guess it's not possible as I found this code in service.skin.widgets :
Code:
def _fetch_seasonthumb(self, tvshowid, seasonnumber):
json_query = xbmc.executeJSONRPC('{"jsonrpc": "2.0", "method": "VideoLibrary.GetSeasons", "params": {"properties": ["season", "thumbnail"], "tvshowid":%s }, "id": 1}' % tvshowid)
json_query = unicode(json_query, 'utf-8', errors='ignore')
json_query = simplejson.loads(json_query)
if json_query.has_key('result') and json_query['result'].has_key('seasons'):
for item in json_query['result']['seasons']:
season = "%.2d" % float(item['season'])
if season == seasonnumber:
thumbnail = item['thumbnail']
return thumbnailAnd as Martijn did not call this function any more, I guess it cost some CPU time
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - Martijn - 2013-09-25
you would need to request it for each episode separate so indeed very time consuming.
not really a problem for one episode but imagine doing that for several playlists with each 20 items
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - mikebzh44 - 2013-09-25
Yes, I have understand this problem. Can be improve by looking if season poster has already been fetch with previous episodes returned but you may have to run this query 10 time for huge collection.
RE: JSON-RPC (JSON Remote Procedure Call) interface protocol in development for XBMC - spambus - 2013-09-26
How can you open a tv channel? In some earlier post something was mentioned about Player.Open and channelid with item
How would an url look like to open a TV channel?
something like this?
http://xbmc:[email protected]:8090/jsonrpc?request={"jsonrpc":"2.0","method":"Player.Open","item":{"channelid":1},"id":1}
but that doesn't work...
