# Revision 1.1 2003/12/12 15:22:30 mikeruelle
# moves tv.mplayer to childapp2
#
# Revision 1.29 2003/11/27 03:11:08 rshortt
# Shuffle things around a little bit and add ivtv capabilities. I intend to
# depricate the ivtv_basic_tv plugin in favour of this once since that is
# just an mplayer plugin as well and I don't want to duplicate too much code.
#
# I will focus my development effort on this plugin instead of ivtv_basic_tv
# and will also be really using this one so I can test it out myself. :)
#
# I am planning on adding dvb support to this plugin as well.
#
# Revision 1.28 2003/11/25 09:37:00 krister
# Bugfixes, works for me now
#
# Revision 1.26.2.3 2003/11/25 01:24:12 rshortt
# Some further fixes and improvements, aldo removed MPLAYER_DEBUG since
# ChildApp does this now.
#
# Please test if you can. VideoGroup configuration is still much undocumented
# but I am planning to do so. Ping me if you need a quick hand.
#
# To test this you must check it out by:
# cvs update -r rob src/tv/plugins/mplayer.py
#
# Revision 1.26.2.2 2003/11/24 17:16:40 rshortt
# Bugfixes.
#
# Revision 1.26.2.1 2003/11/24 13:25:00 rshortt
# Some unstable changes on a branch.
#
# Revision 1.24 2003/11/23 19:53:01 rshortt
# Move some code into src/tv/channels.py and also make use of Freevo's
# frequency tables (and custom frequencies).
#
# This plugin indirectly makes use of the new VIDEO_GROUPS config item.
#
# Please test. I don't have the setup to test this myself.
#
# Revision 1.23 2003/11/06 06:08:38 krister
# Added testcode for viewing the VCR/Composite1 input on the TV card
#
# Revision 1.22 2003/10/28 16:08:14 mikeruelle
# convert to new thread system
#
# Revision 1.21 2003/10/12 09:54:27 dischi
# BSD patches from Lars
#
# Revision 1.20 2003/09/14 01:38:59 outlyer
# More FreeBSD support from Lars
#
# Revision 1.19 2003/09/03 17:54:38 dischi
# Put logfiles into LOGDIR not $FREEVO_STARTDIR because this variable
# doesn't exist anymore.
#
# Revision 1.18 2003/09/02 20:29:53 dischi
# only use mixer if we have one
#
# Revision 1.17 2003/09/01 19:46:03 dischi
# add menuw to eventhandler, it may be needed
#
# Revision 1.16 2003/08/23 12:51:43 dischi
