In my discussion with Pascal Schirrmann (many thanks) I understand some
things.
After that I try to make changes in my config for prepare configuration
which will be work for me.
Some changes:
VIDEO_GROUPS = [
# Use this group for watching tv (PAL)
VideoGroup(vdev=TV_DEVICE,
adev=None,
input_type='tuner',
input_num=0,
tuner_type='internal',
tuner_norm='PAL',
tuner_chanlist=CONF.chanlist,
desc='Default Video Group',
group_type='ivtv',
),
# Use this group for watching tv (SECAM-DK)
VideoGroup(vdev=TV_DEVICE,
adev=None,
input_type='tuner',
input_num=0,
tuner_type='internal',
tuner_norm='SECAM-DK',
tuner_chanlist=CONF.chanlist,
desc='2nd Video Group',
group_type='ivtv',
),
]
TV_CHANNELS = [\
("01",unicode("ORT","koi8-u"),"21"),
("02",unicode("1+1","koi8-u"),"R3",'',1),
]
But 'SECAM-DK' standard is absent in the NORMS dictionary (I add this in
patch) in src/tv/v4l2.py and after I try this configuration I found two
things:
1. In src/tv/plugins/mplayer.py in TV mode (for ivtv) present
ivtv_dev = ivtv.IVTV(vg.vdev)
ivtv_dev.init_settings()
ivtv_dev.setinput(vg.input_num)
but absent setting TV standard.
2. In src/tv/plugins/ivtv_record.py before start record process
present
if DEBUG: print 'Setting Input to %s' % vg.input_num
v.setinput(vg.input_num)
but absent setting TV standard.
I make two patches for this things. See attach.
