Quickstart:
-----------

Just type make and use.

Install:
--------
	1a) git

	git clone git://projects.vdr-developer.org/vdr-plugin-softhddevice.git
	cd vdr-plugin-softhddevice
	make VDRDIR=<path-to-your-vdr-files> LIBDIR=.
	gentoo: make VDRDIR=/usr/include/vdr LIBDIR=.

	2a) tarball

	Download latest version from:
	    http://projects.vdr-developer.org/projects/plg-softhddevice/files

	tar vxf vdr-softhddevice-*.tar.bz2
	cd vdr-softhddevice
	make VDRDIR=<path-to-your-vdr-files> LIBDIR=.

	You can edit Makefile to enable/disable VDPAU / VA-API / Alsa / OSS
	support.

Setup:	environment
------
	Following is supported:

	DISPLAY=:0.0
		x11 display name
    only if alsa is configured
	ALSA_DEVICE=default
		alsa PCM 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_MIXERDEV=/dev/mixer
		oss mixer device name
	OSS_MIXER_CHANNEL=pcm
		oss mixer channel name

Setup: /etc/vdr/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 567i, 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 qualit<69>t)

	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

Setup: /etc/vdr/remote.conf
------

	Add "XKeySym." definitions to /etc/vdr/remote.conf to control
	the vdr and plugin with the connected input device.

	fe.
	XKeySym.Up	Up
	XKeySym.Down	Down
	...

	Additional to the x11 input sends the window close button "Close".

	fe.
	XKeySym.Power	Close

Commandline:
------------

	Use vdr -h to see the command line arguments support by the plugin.

--------

Warning:
--------
	libav is not supported, expect many bugs with it.
