A software and GPU emulated HD output device plugin for VDR.

    o Video decoder CPU / VDPAU
    o Video output VDPAU
    o Audio FFMpeg / Alsa / Analog
    o Audio FFMpeg / Alsa / Digital
    o Audio FFMpeg / OSS / Analog
    o HDMI/SPDIF pass-through
    o Software volume, compression, normalize and channel resample
    o VDR ScaleVideo API
    o Software deinterlacer Bob (VA-API only)
    o Autocrop
    o Grab image (VDPAU only)
    o Suspend / Dettach
    o Letterbox, Stretch and Center cut-out video display modes
    o atmo light support with plugin http://github.com/durchflieger/DFAtmo
    o PIP (Picture-in-Picture) (VDPAU only)

    o planned: Remove VA-API decoder and output support
    o planned: Video decoder OpenMax
    o planned: Video output Opengl / Xv
    o planned: Improved software deinterlacer (yadif or/and ffmpeg filters)
    o XvBa support is no longer planned (use future Radeon UVD VDPAU)

To compile you must have the 'requires' installed.

Good luck

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 supported by the plugin.

    -a audio_device

	Selects audio output module and device.
	""		to disable audio output
	/...		to use oss audio module (if compiled with oss
			support)
	other		to use alsa audio module (if compiled with alsa
			support)

SVDRP:
------

	Use 'svdrpsend.pl plug softhddevice HELP'
	or 'svdrpsend plug softhddevice HELP' to see the SVDRP commands help
	and which are supported by the plugin.

Keymacros:
----------

	See keymacros.conf how to setup the macros.

	This are the supported key sequences:

	@softhddevice Blue 1 0		disable pass-through
	@softhddevice Blue 1 1		enable pass-through
	@softhddevice Blue 1 2		toggle pass-through

	Click into video window to toggle fullscreen/window mode, only if you
	have a window manager running.

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