Available output plugins

While the original softhddevice plugin is not actively maintained anymore, there are multiple forks which concentrate on improving and adding functionality.

At the moment yavdr-ansible for Ubuntu 20.04 (focal) has been adapted to use one of the following outout plugins:

Paketname	VDPAU	CUVID	VAAPI	HEVC	ffmpeg	Comment
vdr-plugin-softhddevice	Yes	No	Yes	Yes (VDPAU, VAAPI)	4.2
vdr-plugin-softhddevice-cuvid	Yes	Yes	Yes	Yes (CUVID, VDPAU, VAAPI)	4.2	as above, but built with cuvid support (set start argument -v cuvid to enable)
vdr-plugin-softhddevice-ffmpeg-2.8	Yes	No	No	No	2.8	original softhddevice plugin, built with ffmpeg 2.8
vdr-plugin-softhddevice-openglosd-ffmpeg-2.8	Yes	No	No	No	2.8	softhddevice-openglosd, build with ffmpeg 2.8 for improved stability
vdr-plugin-softhdvaapi	No	No	Yes	Yes (VAAPI)	4.2
vdr-plugin-softhddrm	No	No	Yes	Yes (VAAPI)	4.2	works without Xorg, direct DRM access
vdr-plugin-softhdcuvid	Yes	Yes	No	Yes (CUVID)	4.2	for nvidia cards with CUDA/CUVID decoder
vdr-plugin-vaapidevice	No	No	Yes	Yes (VAAPI)	4.2	fork of von softhddevice-vpp, vaapi-only, unmaintained
vdr-plugin-xineliboutput	Yes	No	Yes	Yes	4.2	supports VAAPI and VDPAU, works without hardware acceleration in VMs

HEVC can be decoded in hardware with Nvidia GPUs starting with GTX 950/GT 1030 or later and with Intel IGPs beginning with the Skylake generation (more than 8-bit per color channel requires Kabylake or later). Output is limited to 8-bit per color channel. Nvidia cards can output 10-bit via DisplayPort if the monitor supports a 10-bit RGB format.

Known Issues:

softhddevice-vpp

distorted colors with certain Nvidia cards (e.g. GT630 with Kepler chipset)

VDPAU using ffmpeg 3.4/3.3

crashes on certain channels, in this case try a plugin variant which uses ffmpeg 2.8

VDPAU and VAAPI with 3.4

no hardware accleration for HEVC, use a plugin whis has been built using ffmpeg 3.3 instead
