Call a script from HTTP/JSON

Question  2011-01-03, 15:35
is it possible to call a script URL from the HTTP or JSON API?

My example is I want to access the iPlayer plugin to play an iPlayer file.

From looking in the iPlayerv2 plugin I think that the URL would be:

plugin://plugin.video.iplayer/?pid=b00jz2t4

which would cause it to start showing an iPlayer episode. However I don't know how to call this from a remote API.

Whether this is the right way to do it is another question. I was looking into whether the iPlayer plugin could define it's own protocol handler e.g.
iplayer://b00jz2t4/ and translate it into a rtmp:// url for the playlist handler to handle. However I doubt it's possible to create python protocol handler translators (something to add to the 'to-do in the far future' list?)

I'll keep looking, but if anyone familiar with this has an answer that would be great. Thanks!

you can send a play call on url plugin://plugin.video.iplayer/?pid=b00jz2t4 if that is correct url.

Code:
{ "jsonrpc": "2.0", "method": "XBMC.Play", "params": "plugin://plugin.video.iplayer/?pid=b00jz2t4", "id": 1 }

Interesting, I tried that with curl, and it shows the first frame of the video, and then exits. Looking through the debug block shows this is where it stops:

Code:

16:44:11 T:3021797248 M:3696136192   DEBUG: Playlist Player: no more playable items... aborting playback

This appears to mean the script passes off the RTMP stream to the DVD player, and then exits (without giving the right error code). The player catches the exiting of the script as the end of the video (beliveing it to be unplayable?).

Has this usage of a python script to handle a video been thought about, or is this new? Should the script stay running until the program completes (what happens if we exit ourselves) or does it just need to pass the correct return code?

More worryingly. If i run the command again XBMC hangs. the last stuff in xbmc.log is
