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.
