Hi!
I'm writing a small plugin to play karaoke files (cdg) using pykaraoke
(pycdg) from inside freevo.
So far I got this (please note that I'm not a python developer):
--------8<--------
import config, plugin, os, re
from event import *
class PluginInterface(plugin.ItemPlugin):
"""
This plugin should add an option to play the CDG karaoke file if present.
Activate with:
| plugin.activate('audio.karaoke')
"""
def __init__(self):
plugin.ItemPlugin.__init__(self)
def actions(self, item):
if item.type == 'audio':
self.file = None
self.item = item
self.cdgname = ""
self.files = item.files.get()
if (len(self.files) != 1):
return []
self.file = self.files[0]
# now check if there is a matching CDG file
self.cdgname = re.sub('.mp3', '.cdg', self.file)
if os.path.exists(self.cdgname):
return [ ( self.play_cdg , _('Karaoke')) ]
return []
def play_cdg(self, arg=None, menuw=None):
cmd = "pycdg -f \"" + self.cdgname + "\""
os.system(cmd)
--------8<--------
So far so good: in the submenu of mp3 files there will be a new item,
"karaoke", if a cdg file exists with the same basename. When the user
selects this menu item, the plugin will simply launch pycdg. However
it would be really usefull to control pycdg. Since I haven't saw any
slave-mode support, I was thinking of implementing just the EXIT and
STOP events, by simply killing the pycdg process... however I have no
idea how to do that :-(. Any suggestions?
Thanks in advance!
