Artifact e2f164442a09a83b94a3d13b008a75def51cf384:

  • File channels/timer.py — part of check-in [ea628d6426] at 2015-04-08 17:59:53 on branch trunk — Remove extraneous class wrapper action.action. Start to regroup listformat mapping (pls-url → m3u-fn rewrites). Will need some heuristics, as depending just on the channel.listformat assumption won't work in practice (some .pls servers actually host direct server links, or occasionally .m3u references even). Currently does nothing, just returns the pls/etc URL. (user: mario, size: 5948) [annotate] [blame] [check-ins using]

# api: streamtuner2
# title: Recording timer
# description: Schedules play/record events for bookmarked radio stations.
# type: feature
# category: hook
# depends: kronos
# version: 0.6
# config: -
# priority: optional
# support: unsupported
#
# Provides an internal timer, to configure recording and playback times/intervals
# for stations. It accepts a natural language time string when registering a stream.
#
# Context menu > Extension > Add timer
#
# Programmed events are visible in "timer" under the "bookmarks" channel. Times
# are stored in the description field, and can thus be edited. However, after editing
# times manually, streamtuner2 must be restarted for any changes to take effect.
