# Makefile for a Video Disk Recorder plugin

# $Id: 2a41981a57e5e83036463c6a08c84b86ed9d2be3 $

# The official name of this plugin.
# This name will be used in the '-P...' option of VDR to load the plugin.
# By default the main source file also carries this name.


### Configuration (edit this for your needs)
#  comment out if not needed

# what kind of decoder do we make - 
# if VAAPI is enabled the pluginname is softhdvaapi
# if CUVID is enabled the pluginname is softhdcuvid
# if DRM   is enabled the pluginname is softhddrm
#VAAPI=1
CUVID=1

# if you enable DRM then the plugin will only run without X server
# only valid for VAAPI 
# does not work with libplacebo
#DRM=1


# use libplacebo - available for both decoders but not for DRM  
#LIBPLACEBO=1

# use YADIF deint - only available with cuvid
#YADIF=1
