To compile you must have the 'requires' installed.

This is a fork of johns original softhddevice work and I reworked it to support HEVC with CUDA and opengl output.
2018-11-05 10:38:27 +01:00
Currently I have tested it with a GTX 1050 from NVIDIA. SD, HD and UHD is working.
2018-08-19 11:50:09 +02:00
2019-08-22 12:34:29 +02:00
Current Status NVIDIA:
2018-08-19 11:50:09 +02:00
The CUDA driver supports HEVC with 8 Bit and 10 Bit up to UHD resolution. Opengl is able to output also 10 Bit, but NVIDIA does not support to output 10 Bit via HDMI.
2018-12-07 13:07:50 +01:00
Only via DisplayPort you can get 10 Bit output to a compatible screen. This is a restriction from NVIDIA.
2018-08-19 11:50:09 +02:00
2020-03-06 08:59:24 +01:00
Current Status with VAAPI:
I tested it with Intel VAAPI. If you have problmes with the shaders then copy the drirc file in your home directory as .drirc
2020-04-13 18:04:57 +02:00
AMD VAAPI is broken by AMD and will not work currently.
2018-08-19 11:50:09 +02:00
2019-10-28 21:43:37 +01:00
You have to adapt the Makefile to your needs. I use FFMPEG 4.0
2018-08-19 11:50:09 +02:00
2019-10-28 21:43:37 +01:00
This Version supports building with libplacebo. https://github.com/haasn/libplacebo
2018-11-05 10:38:27 +01:00
You have to enable it in the Makefile and install libplacebo yourself.
2018-08-19 11:50:09 +02:00
2020-03-06 08:59:24 +01:00
It also needs the NVIDIA driver 410.48 or newer as well as CUDA 10.
2018-08-19 11:50:09 +02:00
2020-03-06 08:59:24 +01:00
I recommend to use libplacebo. It has much better scaler and does colorconversion for HDR the correct way.
2018-08-19 11:50:09 +02:00
2020-03-06 08:59:24 +01:00
If your FFMEG supports it then you can enable YADIF in the Makefile and select between the buildin NVIDIA CUDA deinterlacer and the YADIF cuda deinterlacer.

Good luck

Quickstart:
-----------
2020-03-06 08:59:24 +01:00
You have to adapt the Makefile. There are 3 possible Version that you can build:
softhdcuvid
2020-04-13 18:04:57 +02:00
This is for NVIDA cards and uses cuvid as decoder. It uses xcb for output and needs a X Server to run.
2020-03-06 08:59:24 +01:00
softhdvaapi
This is for INTEL cards and uses Vaapi as decoder. It uses xcb for output and needs a X Server to run.
2020-04-13 18:04:57 +02:00
2020-03-06 08:59:24 +01:00
softhddrm
2020-04-13 18:04:57 +02:00
This is for INTEL cards and also uses Vaapi as decoder. It uses the DRM API for output and
2020-03-06 08:59:24 +01:00
runs without X Server. There are several commandline options to select the resolution and refresh rate.
2018-08-19 11:50:09 +02:00
Install:
--------
1a) git
git clone git://github.com/jojo61/vdr-plugin-softhdcuvid.git
cd vdr-plugin-softhdcuvid
make
make install
You can edit Makefile to enable/disable Alsa / OSS
support. The default is to autodetect as much as possible.
2018-11-05 10:38:27 +01:00
You have to start vdr with -P 'softhdcuvid -d :0.0 ..< more option > .. '
2018-08-19 11:50:09 +02:00
2020-03-06 08:59:24 +01:00
Beginners Guide for libplacebo:
-------------------------------
2020-04-13 18:04:57 +02:00
When using libplacebo you will find several config options.
2020-03-06 08:59:24 +01:00
First of all you need to set the right scaler for each resolution:
2020-04-13 18:04:57 +02:00
Best you beginn with setting all to "bilinear". If that works ok for you, you can try to change them
for more advanced scaler. I use ewa_robidouxsharp on my GTX1050, but your mileage may vary.
2020-03-06 09:02:27 +01:00
Unfortunatly on INTEL not all scalers may work or crash.
2020-04-13 18:04:57 +02:00
You can enable a Scaler Test feature. When enabled then the screen is split.On the left half you will
see the scaler defined by Scaler Test and on the right side you will see the scaler defined at the
Resolution setting. There is as small black line between the halfs to remaind you that Scaler Test
2020-03-06 09:02:27 +01:00
is activ.
2020-04-13 18:04:57 +02:00
2020-03-06 08:59:24 +01:00
Then you should set the Monitor Colorspace to "sRGB". This guarantees you the best colors on your screen.
2020-04-13 18:04:57 +02:00
At the moment all calculations internaly are done in RGB space and all cards output also RGB.
If you are colorblind you could try to remedy this with the Colorblind Settings. Realy only needed
2020-03-06 09:02:27 +01:00
in rare cases.
2020-04-13 18:04:57 +02:00
2020-03-06 08:59:24 +01:00
All other settings can be in their default state.
2020-06-07 12:56:51 +02:00
Beginning with libplacebo API 58 user shaders from mpv are supported. Use -S parameter to set the shader.
The plugins searches the shaders in $ConfigDir/plugins/shaders for the shaders. One example shader is
provided in the shader subdirectory. Copy it to e.g.: /etc/vdr/plugins/shaders and then start
vdr -P 'softhdcuvid -S filmgrain.glsl ...'
