Added Files:
xine_cvs.py
Log Message:
New version of the xine plugin for DVD. You need the current xine cvs
to get it working. Since sf cvs is 24 hours behind, maybe you need the
patches from http://www.tzi.de/~dmeyer/freevo

# $Id: xine_cvs.py,v 1.1 2003/07/27 19:16:25 dischi Exp $
#
# Notes:
#
# This is a bad hack to make it work. Freevo has _no_ control over
# Xine, the remote or keyboard events are the one from Xine, not
# Freevo. Because of that, this plugin only works for playing a
# DVD. For other files or when you select a specific title, mplayer
# will be taken.
#
# To activate this plugin write plugin.activate('video.xine') in your
# local_conf.py and set XINE_COMMAND to the command line how to start
# xine. For X11 this may be 'xine -V xv -g -f'. Make sure you have
# configured xine correctly. For frambuffer use this is more
# complicated. First set XINE_COMMAND to 'fbxine -V vidixfb' and than
# you have to patch fbxine. fbxine tries to open the keyboard from the
# calling tty, but Freevo called xine, there is no tty. Delete the
# keyboard init in /src/fb/main.c, function fbxine_init. It may also
# be usefull to add '-A <audiosettings> to XINE_COMMAND.
#
#
# Todo:
#
# Again: this is a bad hack. Someone should enhance pyxine or build
# something else above xine-lib to have complete control over xine.

# Very basic Xine support. By loading this plugin and setting XINE_COMMAND
# in the local_conf.py, xine will be used as DVD player when you hit PLAY
# on the item (or SELECT it). In all other cases, mplayer will be taken.
# Xine is only used for DVDnav support. There is no eventhandler, xine
# must be in the foreground and the keys and lirc commands are taken from
# Xine, not Freevo. Only testet with X, I don't know if framebuffer works
# at all.
