In rel-1-6 r8457 I have changed tv/plugins/mplayer and config. The
changes are so that when a VideoGroup has been defined and the adev is
not None then it will pass the adev settings to mplayer. adev is not
used anywhere else so the impact is low.
*But can everybody test it*, I'm not sure how this will work in all cases.
CONTROL_ALL_AUDIO = 0
MPLAYER_AO_DEV = 'alsa'
# video groups
VIDEO_GROUPS = [
VideoGroup(vdev = '/dev/video2',
adev =
'alsa:adevice=hw.1,0:amode=1:audiorate=32000:forceaudio:immediatemode=0',
input_type = 'tuner',
input_num = 0,
tuner_norm = CONF.tv,
tuner_chanlist = CONF.chanlist,
desc = 'Pinnacle 110i Group',
group_type = 'bttv',
record_group = None),
]
Don't copy and paste this verbatim as my video device may be different
from yours.
