ALSA_AC3_DEVICE= alsa AC3/pass-though device name

ALSA_MIXER=default alsa control device name

ALSA_MIXER_CHANNEL=PCM alsa control channel name

only if oss is configured OSS_AUDIODEV=/dev/dsp oss dsp device name

OSS_AC3_AUDIODEV= oss AC3/pass-though device name

OSS_MIXERDEV=/dev/mixer oss mixer device name

OSS_MIXER_CHANNEL=pcm oss mixer channel name

setup.conf

Following is supported:

softhddevice.MakePrimary = 1 0 = no change, 1 make softhddevice primary at start

softhddevice.HideMainMenuEntry = 0 0 = show softhddevice main menu entry, 1 = hide entry

<res> of the next parameters is 576i, 720p, 1080i_fake or 1080i. 1080i_fake is 1280x1080 or 1440x1080 1080i is "real" 1920x1080

softhddevice.<res>.Scaling = 0 0 = normal, 1 = fast, 2 = HQ, 3 = anamorphic

softhddevice.<res>.Deinterlace = 0 0 = bob, 1 = weave, 2 = temporal, 3 = temporal_spatial, 4 = software (only 0, 1 supported with vaapi)

softhddevice.<res>.SkipChromaDeinterlace = 0 0 = disabled, 1 = enabled (for slower cards, poor qualität)

softhddevice.<res>.Denoise = 0 0 .. 1000 noise reduction level (0 off, 1000 max)

softhddevice.<res>.Sharpness = 0 -1000 .. 1000 noise reduction level (0 off, -1000 max blur, 1000 max sharp)

softhddevice.AudioDelay = 0 +n or -n ms

softhddevice.AudioPassthrough = 0 0 = none, 1 = AC-3

for AC-3 the pass-through device is used. softhddevice.AutoCrop.Interval = 0 0 disables auto-crop n each 'n' frames auto-crop is checked.

softhddevice.AutoCrop.Delay = 0 if auto-crop is over 'n' intervals the same, the cropping is used.

softhddevice.AutoCrop.Tolerance = 0 if detected crop area is too small, cut max 'n' pixels at top and bottom.

softhddevice.SkipLines = 0 skip 'n' lines at top and bottom of the video picture.

softhddevice.Suspend.Close = 0 1 suspend closes x11 window, connection and audio device. (use svdrpsend plug softhddevice RESU to resume, if you have no lirc)

softhddevice.Suspend.X11 = 0 1 suspend stops X11 server (not working yet)

Tipps

Audio

• Kein Ton bei 6 Kanal Ton

Entweder kann die Soundkarte kein 6 Kanalton oder libav/ffmpeg hat Probleme beim Umwandeln.

im .asoundrc im Heimverzeichnis des VDR Benutzers oder global zu /etc/asound.conf hinzufügen:

pcm.51to20 {
    type route
    slave.pcm {
        type hw
        card <deine karte>
        device <dein device>
        channels 2
   }
   ttable.0.0 1      # front links -> links
   ttable.1.1 1      # front rechts -> rechts
   ttable.2.0 0.707  # hinten links -> links, Dämpfung 3dB
   ttable.3.1 0.707  # hinten rechts -> rechts, Dämpfung 3dB
   ttable.4.0 0.5    # zentrum -> links, Dämpfung 6dB
   ttable.4.1 0.5    # zentrum -> rechts, Dämpfung 6dB
   ttable.5.0 0.5    # basskanal -> links, Dämpfung 6dB
   ttable.5.1 0.5    # basskanal -> rechts, Dämpfung 6dB
}

Dann bei vdr Argument fürs plugin '--plugin="softhddevice ... -a pcm.51to20 ..."' hinzufügen oder ändern. Dann im Menu -> Setup -> Plugins -> softhddevice -> Audio pass-through None stellen.

• Keine Lautstärkenregelung möglich

Analog softhddevice regelt den "PCM" Regler automatisch. Wenn dieser anders heißt, kann man dies softhddevice mitteilen. Dazu mit "alsamixer" nachsehen wie dieser nun heißt. "Master" regelt alle Eingänge, zur Not kann man diesen nehmen. Bei Rechnern mit 6 Analogen Ausgängen ist es meist "Front". Das Vdr Startscript um

export ALSA_MIXER_CHANNEL=Front

ergänzen. Digital Digitale Ausgänge kann softhddevice nicht regeln. (noch nicht)

Mit diesem Eintrag in asound.conf kann man den Digitalen Ausgang trotzdem regeln.

pcm.!default hdmi_complete
pcm.hdmi_hw {
  type hw
  card 1    #  <- Hier die Nummer der Karte
  device 7  #  <- Nummer des Device
}
pcm.hdmi_formatted {
  type plug
  slave {
    pcm hdmi_hw
    #rate 48000    #  <- Optional! Hier die gewünschte Rate. 
    #channels 2    #  <- Optional! Anzahl der Kanäle.
  }
}
pcm.hdmi_complete {
  type softvol
  slave.pcm hdmi_formatted
  control.name hdmi_volume
  control.card 1    #  <- Hier die Nummer der Karte
} 

Nun muß man noch softhddevice mitteilen, welchen Regler es regeln soll. Dazu das Vdr Startscript um

export ALSA_MIXER_CHANNEL=hdmi_volume

ergänzen.
