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

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

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

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

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

	softhddevice.AudioDelay = 0
	+n or -n ms

------------

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